It is called column visibility and enables expressive -cell-level access control. Authorizations are passed with each query to control -what data is returned to the user. The column visibilities are boolean AND and -OR combinations of arbitrary strings (such as â(A&B)|Câ) and authorizations -are sets of strings (such as {C,D}).</p> - -<h3 id="constraints">Constraints</h3> - -<p>Configurable conditions under which writes to a table will be rejected. -Constraints are written in Java and configurable on a per table basis.</p> - -<h3 id="sharding">Sharding</h3> - -<p>Through the use of specialized iterators, Accumulo can be a parallel sharded -document store. For example wikipedia could be stored and searched for -documents containing certain words.</p> - -<h3 id="large-rows">Large Rows</h3> - -<p>When reading rows, there is no requirement that an entire row fits into memory.</p> - -<h3 id="namespaces">Namespaces</h3> - -<p>In version 1.6.0, the concept of table ânamespacesâ was created to allow for logical -grouping and configuration of Accumulo tables. By default, tables are created in a -default namespace which is the empty string to preserve the feel for how tables operate -in previous versions. One application of table namespaces is placing the Accumulo root -and metadata table in an âaccumuloâ namespace to denote that these tables are used -internally by Accumulo.</p> - -<h3 id="volume-support">Volume support</h3> - -<p>Accumulo 1.6.0 migrated away from configuration of HDFS by using a single HDFS host and -directory, to a collection of HDFS URIs (host and path) which allows Accumulo to operate -over multiple disjoint HDFS instances. This allows Accumulo to scale beyond the limits -of a single namenode. When used in conjunction with HDFS federation, multiple namenodes -can share a pool of datanodes.</p> - -<h2 id="integrityavailability">Integrity/Availability</h2> - -<h3 id="master-fail-over">Master fail over</h3> - -<p>Multiple masters can be configured. Zookeeper locks are used to determine -which master is active. The remaining masters simply wait for the current -master to lose its lock. Current master state is held in the metadata table -and Zookeeper (see <a href="#fate">FATE</a>).</p> - -<h3 id="logical-time">Logical time</h3> - -<p>A mechanism to ensure that server set times never go backwards, even when time -across the cluster is incorrect. This ensures that updates and deletes are not -lost. If a tablet is served on machine with time a year in the future, then the -tablet will continue to issue new timestamps a year in the future even when it -moves to another server. In this case the timestamps preserve ordering, but -lose their meaning. In addition to logical time, Accumulo has master -authoritative time. The master averages the time of all of the tablet servers -and sends this back to the tablet servers. Tablet servers use this information -to adjust the timestamps they issue. So logical time ensures ordering is -always correct and master authoritative time tries to ensure that timestamps -are meaningful.</p> - -<h3 id="logical-time-for-bulk-import">Logical Time for bulk import</h3> - -<p>Logical time as described above works with streaming (batch) ingest, where the -tablet server assigns the timestamp. Logical time is also important for bulk -imported data, for which the client code may be choosing a timestamp. Accumulo -uses specialized system iterators to lazily set times in a bulk imported -file. This mechanism guarantees that times set by unsynchronized multi-node -applications (such as those running on MapReduce) will maintain some semblance -of causal ordering. This mitigates the problem of the time being wrong on the -system that created the file for bulk import. These times are not set when the -file is imported, but whenever it is read by scans or compactions. At import, a -time is obtained and always used by the specialized system iterator to set that -time.</p> - -<h3 id="fate">FATE</h3> - -<p>Fault Tolerant Executor. A framework for executing operations in a fault -tolerant manner. In the previous release, if the master process died in the -middle of creating a table it could leave the system in an inconsistent state. -With this new framework, if the master dies in the middle of create table it -will continue on restart. Also the client requesting the create table operation -will never know anything happened. The framework serializes work in Zookeeper -before attempting to do the work. Clients start a FATE transaction, seed it -with work, and then wait for it to finish. Most table operations are executed -using this framework. Persistent, per table, read-write locks are created in -Zookeeper to synchronize operations across process faults.</p> - -<h3 id="scalable-master">Scalable master</h3> - -<p>Stores its metadata in an Accumulo table and Zookeeper.</p> - -<h3 id="isolation">Isolation</h3> - -<p>Scans will not see data inserted into a row after the scan of that row begins.</p> - -<h2 id="performance">Performance</h2> - -<h3 id="relative-encoding">Relative encoding</h3> - -<p>If consecutive keys have identical portions (row, colf, colq, or colvis), there -is a flag to indicate that a portion is the same as that of the previous key. -This is applied when keys are stored on disk and when transferred over the -network. Starting with 1.5, prefix erasure is supported. When its cost -effective, prefixes repeated in subsequent key fields are not repeated.</p> - -<h3 id="native-in-memory-map">Native In-Memory Map</h3> - -<p>By default data written is stored outside of Java managed memory into a C++ STL -map of maps. It maps rows to columns to values. This hierarchical structure -improves performance of inserting a mutation with multiple column values in a -single row. A custom STL allocator is used to avoid the global malloc lock and -memory fragmentation.</p> - -<h3 id="scan-pipeline">Scan pipeline</h3> - -<p>A long running Accumulo scan will eventually cause multiple threads to start. -One server thread to read data from disk, one server thread to serialize and -send data, and one client thread to deserialize and read data. When pipelining -kicks in, it substantially increases scan speed while maintaining key order. It -does not activate for short scans.</p> - -<h3 id="caching">Caching</h3> - -<p>Recently scanned data is cached into memory. There are separate caches for -indexes and data. Caching can be turned on and off for individual tables.</p> - -<h3 id="multi-level-rfile-index">Multi-level RFile Index</h3> - -<p>RFiles store an index of the last key in each block. For large files the index -can become quite large. When the index is large a lot of memory is consumed and -files take a long time to open. To avoid this problem, RFiles have a -multi-level index tree. Index blocks can point to other index blocks or data -blocks. The entire index never has to be resident, even when the file is -written. When an index block exceeds the configurable size threshold, its -written out between data blocks. The size of index blocks is configurable on a -per table basis.</p> - -<h3 id="binary-search-in-rfile-blocks">Binary search in RFile blocks</h3> - -<p>RFile uses its index to locate a block of key values. Once it reaches a block -it performs a linear scan to find a key on interest. Accumulo will generate -indexes of cached blocks in an adaptive manner. Accumulo indexes the blocks -that are read most frequently. When a block is read a few times, a small index -is generated. As a block is read more, larger indexes are generated making -future seeks faster. This strategy allows Accumulo to dynamically respond to -read patterns without precomputing block indexes when RFiles are written.</p> - -<h2 id="testing">Testing</h2> - -<h3 id="mock">Mock</h3> - -<p>The Accumulo client API has a mock implementation that is useful writing unit -test against Accumulo. Mock Accumulo is in memory and in process.</p> - -<h3 id="mini-accumulo-cluster">Mini Accumulo Cluster</h3> - -<p>Mini Accumulo cluster is a set of utility code that makes it easy to spin up -a local Accumulo instance running against the local filesystem. Mini Accumulo -is slower than Mock Accumulo, but its behavior mirrors a real Accumulo -instance more closely.</p> - -<h3 id="accumulo-maven-plugin">Accumulo Maven Plugin</h3> - -<p>Using the Mini Accumulo Cluster in unit and integration tests is a great way for -developers to test their applications against Accumulo in an environment that is -much closer to physical deployments than Mock Accumulo provided. Accumulo 1.6.0 also -introduced a <a href="/release/accumulo-1.6.0/#maven-plugin">maven-accumulo-plugin</a> which -can be used to start a Mini Accumulo Cluster instance as a part of the Maven -lifecycle that your application tests can use.</p> - -<h3 id="functional-test">Functional Test</h3> - -<p>Small, system-level tests of basic Accumulo features run in a test harness, -external to the build and unit-tests. These tests start a complete Accumulo -instance, and require Hadoop and Zookeeper to be running. They attempt to -simulate the basic functions of Accumulo, as well as common failure conditions, -such as lost disks, killed processes, and read-only file systems.</p> - -<h3 id="scale-test">Scale Test</h3> - -<p>A test suite that verifies data is not lost at scale. This test runs many -ingest clients that continually create linked lists containing 25 million -nodes. At some point the clients are stopped and a map reduce job is run to -ensure no linked list has a hole. A hole indicates data was lost by Accumulo. -The Agitator can be run in conjunction with this test to randomly kill tablet -servers. This test suite has uncovered many obscure data loss bugs. This test -also helps find bugs that impact uptime and stability when run for days or -weeks.</p> - -<h3 id="random-walk-test">Random Walk Test</h3> - -<p>A test suite that looks for unexpected system states that may emerge in -plausible real-world applications. Application components are defined as test -nodes (such as create table, insert data, scan data, delete table, etc.), and -are programmed as Java classes that implement a specified interface. The nodes -are connected together in a graph specified in an XML document. Many processes -independently and concurrently execute a random walk of the test graphs. Some -of the test graphs have a concept of correctness and can verify data over time. -Other tests have no concept of data correctness and have the simple goal of -crashing Accumulo. Many obscure bugs have been uncovered by this testing -framework and subsequently corrected.</p> - -<h2 id="client-api">Client API</h2> - -<h3 id="batch-scanner4"><a href="/1.5/accumulo_user_manual#_writing_accumulo_clients">Batch Scanner</a></h3> - -<p>Takes a list of Ranges, batches them to the appropriate tablet servers, and -returns data as it is received (i.e. not in sorted order).</p> - -<h3 id="batch-writer4"><a href="/1.5/accumulo_user_manual#_writing_accumulo_clients">Batch Writer</a></h3> - -<p>Clients buffer writes in memory before sending them in batches to the -appropriate tablet servers.</p> - -<h3 id="bulk-import6"><a href="/1.5/accumulo_user_manual#_bulk_ingest">Bulk Import</a></h3> - -<p>Instead of writing individual mutations to Accumulo, entire files of sorted key -value pairs can be imported. These files are moved into the Accumulo directory -and referenced by Accumulo. This feature is useful for ingesting a large amount -of data. This method of ingest usually offers higher throughput at the cost of -higher latency for data availability for scans. Usually the data is sorted -using map reduce and then bulk imported. This method of ingest also allows for -flexibility in resource allocation. The nodes running map reduce to sort data -could be different from the Accumulo nodes.</p> - -<h3 id="map-reduce4"><a href="/1.5/accumulo_user_manual#_writing_accumulo_clients">Map Reduce</a></h3> - -<p>Accumulo can be a source and/or sink for map reduce jobs.</p> - -<h3 id="apache-thrift-proxy">Apache Thrift Proxy</h3> - -<p>The Accumulo client code contains a lot of complexity. For example, the -client code locates tablets, retries in the case of failures, and supports -concurrent reading and writing. All of this is written in Java. The thrift -proxy wraps the Accumulo client API with thrift, making this API easily -available to other languages like Python, Ruby, C++, etc.</p> - -<h3 id="conditional-mutations">Conditional Mutations</h3> - -<p>In version 1.6.0, Accumulo introduced <a href="/1.6/accumulo_user_manual#_conditionalwriter">ConditionalMutations</a> -which allow users to perform efficient, atomic read-modify-write operations on rows. Conditions can -be defined using on equality checks of the values in a column or the absence of a column. For more -information on using this feature, users can reference the Javadoc for <a href="/1.6/apidocs/org/apache/accumulo/core/data/ConditionalMutation">ConditionalMutation</a> and -<a href="/1.6/apidocs/org/apache/accumulo/core/client/ConditionalWriter">ConditionalWriter</a>.</p> - -<h3 id="lexicoders">Lexicoders</h3> - -<p>Common boilerplate code that exists when interacting with Accumulo is the conversion -of Java objects to lexicographically sorted bytes, e.g. ensure that the byte representation -of the number 9 sorts before the byte representation of the number 11. Version 1.6.0 introduced -Lexicoders which have numerous implementations that support for efficient translation from common -Java primitives to byte arrays and vice versa. These classes can greatly reduce the burden in -re-implementing common programming mistakes in encoding.</p> - -<h2 id="extensible-behaviors">Extensible Behaviors</h2> - -<h3 id="pluggable-balancer">Pluggable balancer</h3> - -<p>Users can provide a balancer plugin that decides how to distribute tablets -across a table. These plugins can be provided on a per table basis. This is -useful for ensuring a particular tableâs tablets are placed optimally for -tables with special query needs. The default balancer randomly spreads each -tableâs tablets across the cluster. It takes into account where a tablet was -previously hosted to leverage locality. When a tablet splits, the default -balancer moves one child to another tablet server. The assumption here is that -splitting tablets are being actively written to, so this keeps write load evenly -spread.</p> - -<h3 id="pluggable-memory-manager">Pluggable memory manager</h3> - -<p>The plugin that decides when and what tablets to minor compact is configurable. -The default plugin compacts the largest tablet when memory is over a certain -threshold. It varies the threshold over time depending on minor compaction -speed. It flushes tablets that are not written to for a configurable time -period.</p> - -<h3 id="pluggable-logger-assignment-strategy">Pluggable logger assignment strategy</h3> - -<p>The plugin that decided which loggers should be assigned to which tablet -servers is configurable.</p> - -<h3 id="pluggable-compaction-strategy">Pluggable compaction strategy</h3> - -<p>The plugin that decides which files should be chosen for major compaction is now -configurable. Given certain workloads, it may be known that once data is written, -it is very unlikely that more data will be written to it, and thus paying the penalty -to re-write a large file can be avoided. Implementations of this compaction strategy -can be used to optimize the data that compactions will write.</p> - -<h2 id="general-administration">General Administration</h2> - -<h3 id="monitor-page">Monitor page</h3> - -<p>A simple web server provides basic information about the system health and -performance. It displays table sizes, ingest and query statistics, server -load, and last-update information. It also allows the user to view recent -diagnostic logs and traces.</p> - -<h3 id="tracing">Tracing</h3> - -<p>It can be difficult to determine why some operations are taking longer than -expected. For example, you may be looking up items with very low latency, but -sometimes the lookups take much longer. Determining the cause of the delay is -difficult because the system is distributed, and the typical lookup is fast. -Accumulo has been instrumented to record the time that various operations take -when tracing is turned on. The fact that tracing is enabled follows all the -requests made on behalf of the user throughout the distributed infrastructure -of Accumulo, and across all threads of execution.</p> - -<h3 id="online-reconfiguration">Online reconfiguration</h3> - -<p>System and per table configuration is stored in Zookeeper. Many, but not all, -configuration changes take effect while Accumulo is running. Some do not take -effect until server processes are restarted.</p> - -<h3 id="table-renaming">Table renaming</h3> - -<p>Tables can be renamed easily because Accumulo uses internal table IDs and -stores mappings between names and IDs in Zookeeper.</p> - -<h2 id="internal-data-management">Internal Data Management</h2> - -<h3 id="locality-groups">Locality groups</h3> - -<p>Groups columns within a single file. There is a default locality group so that -not all columns need be specified. The locality groups can be restructured -while the table is online and the changes will take effect on the next -compaction. A tablet can have files with different locality group -configurations. In this case scans may be suboptimal, but correct, until -compactions rewrite all files. After reconfiguring locality groups, a user can -force a table to compact in order to write all data into the new locality -groups. Alternatively, the change could be allowed to happen over time as -writes to the table cause compactions to happen.</p> - -<h3 id="smart-compaction-algorithm">Smart compaction algorithm</h3> - -<p>It is inefficient to merge small files with large files. Accumulo merges files -only if all files are larger than a configurable ratio (default is 3) -multiplied by the largest file size. If this cannot be done with all the -files, the largest file is removed from consideration, and the remaining files -are considered for compaction. This is done until there are no files to merge.</p> - -<h3 id="merging-minor-compaction">Merging Minor Compaction</h3> - -<p>When a max number of files per tablet is reached, minor compactions will merge -data from the in-memory map with the smallest file instead of creating new -files. This throttles ingest. In previous releases new files were just created -even if major compactions were falling behind and the number of tablets per file -was growing. Without this feature, ingest performance can roughly continue at a -constant rate, even as scan performance decreases because tablets have too many -files.</p> - -<h3 id="loading-jars-using-vfs">Loading jars using VFS</h3> - -<p>User written iterators are a useful way to manipulate data in data in Accumulo. -Before 1.5., users had to copy their iterators to each tablet server. Starting -with 1.5 Accumulo can load iterators from HDFS using Apache commons VFS.</p> - -<h3 id="encryption">Encryption</h3> - -<p>Still a work in progress, Accumulo 1.6.0 introduced encryption at rest (RFiles -and WriteAheadLogs) and wire encryption (Thrift over SSL) to provide enhance the -level of security that Accumulo provides. It is still a work in progress because -the intermediate files created by Accumulo when recovering from a TabletServer -failure are not encrypted.</p> - -<h2 id="on-demand-data-management">On-demand Data Management</h2> - -<h3 id="compactions">Compactions</h3> - -<p>Ability to force tablets to compact to one file. Even tablets with one file are -compacted. This is useful for improving query performance, permanently -applying iterators, or using a new locality group configuration. One example -of using iterators is applying a filtering iterator to remove data from a -table. Additionally, users can initiate a compaction with iterators only applied to -that compaction event.</p> - -<h3 id="split-points">Split points</h3> - -<p>Arbitrary split points can be added to an online table at any point in time. -This is useful for increasing ingest performance on a new table. It can also be -used to accommodate new data patterns in an existing table.</p> - -<h3 id="tablet-merging">Tablet Merging</h3> - -<p>Tablet merging is a new feature. Merging of tablets can be requested in the -shell; Accumulo does not merge tablets automatically.

A cloned table and its source table can be -mutated independently. Testing was the motivating reason behind this new -feature. For example to test a new filtering iterator, clone the table, add the -filter to the clone, and force a major compaction.</p> - -<h3 id="importexport-table">Import/Export Table</h3> - -<p>An offline tables metadata and files can easily be copied to another cluster and -imported.</p> - -<h3 id="compact-range">Compact Range</h3> - -<p>Compact each tablet that falls within a row range down to a single file.</p> - -<h3 id="delete-range">Delete Range</h3> - -<p>Added an operation to efficiently delete a range of rows from a table.

Here is how RB can -be used to support development in the context of the -<a href="/bylaws">Apache Accumulo bylaws</a>.</p> - -<p>Contributors to Accumulo are encouraged to use RB for non-trivial patches and -any time feedback is desired. No one is required to use RB, but its ready -availability and better interface for feedback can help with reviews. Committers -seeking review prior to pushing changes can also benefit similarly.</p> - -<h2 id="roles-for-review-board">Roles for Review Board</h2> - -<h3 id="optional-pre-commit-review">Optional Pre-Commit Review</h3> - -<p>Accumulo operates under the <a href="https://www.apache.org/foundation/glossary#CommitThenReview";>Commit-Then-Review</a> (CtR) policy, so code -review does not need to occur prior to commit. However, a committer may opt to -hold a code review before commit for changes that, in their opinion, would -benefit from additional attention. RB can be used to conduct such code reviews.</p> - -<h3 id="consensus-approval-after-a-code-change-veto">Consensus Approval after a Code Change Veto</h3> - -<p>Code changes are approved by lazy approval, with consensus approval following -a veto (see the <a href="/bylaws#actions">Actions</a> section of the bylaws). RB can be used -to coordinate a consensus approval vote by providing a convenient view of the -code change under consideration. The vote itself must still be held on the -developer mailing list.</p> - -<h2 id="guidelines-for-posting-a-review">Guidelines for Posting a Review</h2> - -<ul> - <li>It is best to post a git-generated patch as the basis for a review. RB does -not support patches containing multiple commits, so either squash commits -first, or submit a diff spanning the changeset. The <code class="highlighter-rouge">rbt</code> and <code class="highlighter-rouge">post-review</code> -tools generate diffs.</li> - <li>Strive to make your changes small. Reviewers are less likely to want to -trudge through a review with lots of changes, and are more likely to miss -problems.</li> - <li>Begin the summary of the review with a JIRA issue number. A review must -always be associated with a JIRA issue. The issue number should also be -entered in the âBugsâ field of the review, providing a link to JIRA.</li> - <li>The âBranchâ field should contain the name of the branch that the code change -is based on (e.g., the base of your git feature branch).</li> - <li>Include the âaccumuloâ user group as reviewers. Also include specific people -as individual reviewers, even if they are in the âaccumuloâ group, if you -deem them of primary importance for the review (e.g., you have been working -out problems with the review with them, they are expert in the area).</li> - <li>Use the description to summarize the change under review. Include helpful -instructions to the reviewers here.</li> - <li>Describe any testing done on the change. It is not expected that reviewers -will do their own testing, and they may reject the review if you have not -done sufficient testing yourself.</li> - <li>Avoid submitting generated code for review if it can be reproduced by a -reviewer.</li> -</ul> - -<p>After the review is published, set the status of the associated JIRA issue to -âPatch Availableâ as a signal to reviewers. Also, link to the review from the -issue (More -> Link -> Web Link) to help viewers of the issue find the review -and assess its progress.</p> - -<h2 id="guidelines-for-reviewing-code">Guidelines for Reviewing Code</h2> - -<ul> - <li>Try to associate comments with relevant lines of code in the review.</li> - <li>By default, each comment opens a review issue. If a comment pertains to -something that should not block the review from completing successfully, then -clear the âOpen an issueâ checkbox before saving your feedback. Examples that -might qualify as non-issues: minor formatting/whitespace issues, spelling -mistakes, general background questions.</li> - <li>If a review looks good, be sure to âShip Itâ by either using the âShip It!â -button or by submitting a general review with the âShip Itâ checkbox checked.</li> -</ul> - -<h2 id="guidelines-for-completing-a-review">Guidelines for Completing a Review</h2> - -<p>These guidelines do not apply to consensus approval votes, since the vote -completion depends on the votes registered in the developer mailing list.</p> - -<ul> - <li>Use your judgement for the number of âShip Itâs you want to receive to -consider a review passed. Usually, getting one âShip Itâ is enough to proceed -with a commit. It is recommended that the âShip Itâ be from a committer who -is a neutral party not involved in the change under review.</li> - <li>Use your judgement for the minimum time length you set for the review. Simple -changes can be up for just a day, while complex ones should take up to seven.</li> - <li>Review time should be extended in the face of problems discovered in the -review. Update the review with improved code instead of discarding (i.e., -closing unsuccessfully) it and beginning a new one.</li> - <li>A review should not be âsubmittedâ (i.e., closed successfully) unless there -are no outstanding issues. Check with reviewers to ensure that their issues -are resolved satisfactorily.</li> - <li>A review should be âdiscardedâ if the code requires major rework or it -becomes obvious it should never be committed (due to design changes, -becoming overcome by events, being back-burnered, etc.).</li> - <li>Donât leave a review open indefinitely. Once you have received sufficient -feedback to submit or discard it, do so. If there has been no activity for -some time, discard the review. A new one can always be created later.</li> -</ul> - -<p>Once youâve closed a review as submitted, if you are unable to commit your -changes yourself, attach the final version of them to the relevant JIRA issue. -They should be in the form of a patch containing a single commit, -<a href="/git#contributors">per the final steps of the contribution process</a>.</p> - - - </div> - - -<footer> - - <p><a href="https://www.apache.org";><img src="/images/feather-small.gif" alt="Apache Software Foundation" id="asf-logo" height="100" /></a></p> - - <p>Copyright © 2011-2016 The Apache Software Foundation.
