New features ------------ - - Nodes will now bootstrap all intra-cluster connections at startup by default and wait - 10 seconds for the all but one node in the local data center to be connected and marked - UP in gossip. This prevents nodes from coordinating requests and failing because they - aren't able to connect to the cluster fast enough. block_for_peers_timeout_in_secs in - cassandra.yaml can be used to configure how long to wait (or whether to wait at all) - and block_for_peers_in_remote_dcs can be used to also block on all but one node in - each remote DC as well. See CASSANDRA-14297 and CASSANDRA-13993 for more information. - - *Experimental* support for Transient Replication and Cheap Quorums introduced by CASSANDRA-14404 - The intended audience for this functionality is expert users of Cassandra who are prepared - to validate every aspect of the database for their application and deployment practices. Future - releases of Cassandra will make this feature suitable for a wider audience. - - *Experimental* support for Java 11 has been added. JVM options that differ between or are - specific for Java 8 and 11 have been moved from jvm.options into jvm8.options and jvm11.options. - IMPORTANT: Running C* on Java 11 is *experimental* and do it at your own risk. - Compilation recommendations: configure Java 11 SDK via JAVA_HOME and Java 8 SDK via JAVA8_HOME. - Release builds require Java 11 + Java 8. Development builds can use Java 8 without 11. - - LCS now respects the max_threshold parameter when compacting - this was hard coded to 32 - before, but now it is possible to do bigger compactions when compacting from L0 to L1. - This also applies to STCS-compactions in L0 - if there are more than 32 sstables in L0 - we will compact at most max_threshold sstables in an L0 STCS compaction. See CASSANDRA-14388 - for more information. - - There is now an option to automatically upgrade sstables after Cassandra upgrade, enable - either in `cassandra.yaml:automatic_sstable_upgrade` or via JMX during runtime. See - CASSANDRA-14197. - - `nodetool refresh` has been deprecated in favour of `nodetool import` - see CASSANDRA-6719 - for details - - An experimental option to compare all merkle trees together has been added - for example, in - a 3 node cluster with 2 replicas identical and 1 out-of-date, with this option enabled, the - out-of-date replica will only stream a single copy from up-to-date replica. Enable it by adding - "-os" to nodetool repair. See CASSANDRA-3200. - - The currentTimestamp, currentDate, currentTime and currentTimeUUID functions have been added. - See CASSANDRA-13132 - - Support for arithmetic operations between `timestamp`/`date` and `duration` has been added. - See CASSANDRA-11936 - - Support for arithmetic operations on number has been added. See CASSANDRA-11935 - - Preview expected streaming required for a repair (nodetool repair --preview), and validate the - consistency of repaired data between nodes (nodetool repair --validate). See CASSANDRA-13257 - - Support for selecting Map values and Set elements has been added for SELECT queries. See CASSANDRA-7396 - - Change-Data-Capture has been modified to make CommitLogSegments available - immediately upon creation via hard-linking the files. This means that incomplete - segments will be available in cdc_raw rather than fully flushed. See documentation - and CASSANDRA-12148 for more detail. - - The initial build of materialized views can be parallelized. The number of concurrent builder - threads is specified by the property `cassandra.yaml:concurrent_materialized_view_builders`. - This property can be modified at runtime through both JMX and the new `setconcurrentviewbuilders` - and `getconcurrentviewbuilders` nodetool commands. See CASSANDRA-12245 for more details. - - There is now a binary full query log based on Chronicle Queue that can be controlled using - nodetool enablefullquerylog, disablefullquerylog, and resetfullquerylog. The log - contains all queries invoked, approximate time they were invoked, any parameters necessary - to bind wildcard values, and all query options. A human readable version of the log can be - dumped or tailed using the new bin/fqltool utility. The full query log is designed to be safe - to use in production and limits utilization of heap memory and disk space with limits - you can specify when enabling the log. - See nodetool and fqltool help text for more information. - - SSTableDump now supports the -l option to output each partition as it's own json object - See CASSANDRA-13848 for more detail - - Metric for coordinator writes per table has been added. See CASSANDRA-14232 - - Nodetool cfstats now has options to sort by various metrics as well as limit results. - - Operators can restrict login user activity to one or more datacenters. See `network_authorizer` - in cassandra.yaml, and the docs for create and alter role statements. CASSANDRA-13985 - - Roles altered from login=true to login=false will prevent existing connections from executing any - statements after the cache has been refreshed. CASSANDRA-13985 - - Support for audit logging of database activity. If enabled, logs every incoming - CQL command request, Authentication (successful as well as unsuccessful login) to a node. - - Faster streaming of entire SSTables using ZeroCopy APIs. If enabled, Cassandra will use stream - entire SSTables, significantly speeding up transfers. Any streaming related operations will see - corresponding improvement. See CASSANDRA-14556. - - NetworkTopologyStrategy now supports auto-expanding the replication_factor - option into all available datacenters at CREATE or ALTER time. For example, - specifying replication_factor: 3 translates to three replicas in every - datacenter.
