Igniters, We've uploaded a 2.5.0 release candidate to https://dist.apache.org/repos/dist/dev/ignite/2.5.0-rc1/
Git tag name is 2.5.0-rc1 This release includes the following changes: Ignite: * Implemented Zookeeper discovery SPI. * Added Java thin client. * Added continuous queries with transformers. * Implemented general approach for critical failures handling. * Added the new method IgniteMXBean.getCurrentCoordinatorFormatted() which displays formatted information about current coordiantor. * Added partition update counters verification on partition map exchange. * Added ability to disable WAL during initial data rebalancing. * Added additional data storage metrics * Added additional transactional metrics. * Added DEB package and improved RPM package. * Added information about fields serialization/deserialization errors in BinaryMarshaller. * Added configurable automatic rollback timeout for pending transactions preventing partition map exchange to complete. * Added preventing infinite iterations of corrupted B+Tree. New IGNITE_BPLUS_TREE_LOCK_RETRIES property was added, default value is Integer.MAX_VALUE. * Implemented handling of broken segment in WAL compaction. * Fixed affinity to always choose primary node from one of the owners when persistence is enabled. * Partition eviction now does not block exchange. * Fixed the issue that prevented rebalancing on a new baseline node join. * Fixed potential deadlock during preloading. * Fixed exception handling in IsolatedUpdater of DataStreamer. * Fixed the issue when ComputeTaskFuture.get() threw a trimmed exception chain: now full exception chain is propagated to the caller; the exception thrown from IgniteCompute methods may now differ from the previous behavior. * Fixed null value being passed to entry processor when such entry actually exists. * Fixed problem when cluster could not survive after IgniteOutOfMemoryException. * Fixed NullPointerException on batch atomic cache operations with cache store. * Fixed bug with ScanQuery transformer which applies to the first result page only. * Fixed hanging of node stopping in case when node is invalidated and persistence is enabled. * BinaryMetadata exchange is triggered only if there are actual changes in BinaryMetadata. * Fixed contention while executing parallel atomic single get operations. * Fixed cache metadata corruption during concurrent checkpoint and cache destroy. * Implemented additional synchronization for correct partition counters update on partition map exchange. * Optimized checkpoint lock acquisition for demander thread. * Destroyed caches with enabled persistence now will not survive grid restart. * Nodes with incompatible SQL metadata will not be able to join grid. This fixes known case for index corruption. * Fixed fillFactor memory metric value. * Fixed bug with checkpoint buffer overflow with enabled throttling. * Fixed crash recovery problem when index tree could reference to removed data pages. * Fixed error during cluster initialization with partially acceptable WAL archive. * Fixed issue with local partitions size changing inside checkpoint write lock. * Fixed LOG_ONLY and BACKGROUND modes to be power-crash resistant. * Fixed incorrect finishing of implicit transactions on unstable topology. * Fixed incorrect mapping of smallint Cassandra type. * Introduced log markers support to IgniteLogger and standard DEV_ONLY marker. * Changed Log4J and Log4J2 adapters to update active logger configuration when configuration source file is modified. * Fixed sqlline.sh script to use Java from JAVA_HOME. * Improved Docker image build. * Default and recommended JVM options are updated. Ignite .Net: * Added SSL configuration for node-to-node links. * Added dynamic service proxies. * Propagated query metrics to ICache.GetQueryMetrics() and ICache.ResetQueryMetrics(). * DML update via LINQ. * Fixed hang caused by mishandled exception during custom cache store deserialization. * Fixed GroupBy and Where issues in LINQ. * .Net thin client SSL support. Ignite C++: * Fixed bug with LocalSize cache method. SQL: * Implemented COPY command for fast data load. * Added support of authorization for CREATE TABLE and DROP TABLE commands. * Improved deadlock handling in DML. * Added IGNITE_SQL_FORCE_LAZY_RESULT_SET option to force all SQL queries on node using lazy result set. * Fixed SQL query hang if cluster contains nodes not in baseline. JDBC: * Added SSL support. * Added authentication. * Added streaming mode to thin driver. * Semicolon now can be used as delimiter for properties in URL string. * Changed default socket buffer size to 64Kb in thin driver. * Added FQDN to thin client in order to support multiple IPs for connection establishment. ODBC: * Added SSL support. * Implemented username/password authentication. * Added support of multiple addresses in connection string. * Added support for SQL_ATTR_LOGIN_TIMEOUT. Web Console: * Added support for persistence in demo mode. * Configuration screen is reworked to new modern design with improved usability. * Implemented support for comma-separated list of node URIs. * Fixed Docker file generation. * Fixed code generation for large numbers in configuration params. * Fixed demo for non-collocated joins. * Fixed enum values decoding for SQL queries. * Upgraded build to use Webpack 4. REST: * Added AUTHENTICATE command. * Added support for new authentication API. * Implemented possibility to get values from cache inserted via API or SQL. * Enhanced GET_OR_CREATE_CACHE command with optional "templateName", "backups", "cacheGroup", "dataRegion" and "writeSynchronizationMode" options. * Added support of Java built-in types (boolean, int, long, ..., UUID) for put/get operations. Visor: * Added "cache -slp" and "cache -rlp" commands to show and reset lost partitions for specified cache. * Added scan queries of near cache support. Control utility: * Added utilities to control.sh script to display cache info. * Added new tools (control.sh --tx, TransactionsMXBean) to view active transactions and ability to kill them . * Added confirmation on dangerous operations. * Fixed NullPointerException in case of empty base line and not active cluster. * Fixed timeout on changing baseline in control.sh ML: * Implemented framework for genetic algorithms over Apache Ignite caches. * Implemented LSQR-based linear regression. * Implemented Linear SVM for binary classification. * Implemented distributed version of SVM (support vector machine) algoritm.
