> Igniters, > > We've uploaded a 2.7.0 release candidate to > > https://dist.apache.org/repos/dist/dev/ignite/2.7.0-rc1/ > > Git tag name is 2.7.0-rc1 > > This release includes the following changes: > > Apache Ignite In-Memory Database and Caching Platform 2.7 > --------------------------------------------------------- > > Ignite: > * Added experimental support for multi-version concurrency control with > snapshot isolation > - available for both cache API and SQL > - use CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT to enable it > - not production ready, data consistency is not guaranteed in case of > node failures > * Implemented Transparent Data Encryption based on JKS certificates > * Implemented Node.JS Thin Client > * Implemented Python Thin Client > * Implemented PHP Thin Client > * Ignite start scripts now support Java 9 and higher > * Added ability to set WAL history size in bytes > * Added SslContextFactory.protocols and SslContextFactory.cipherSuites > properties to control which SSL encryption algorithms can be used > * Added JCache 1.1 compliance > * Added IgniteCompute.withNoResultCache method with semantics similar to > ComputeTaskNoResultCache annotation > * Spring Data 2.0 is now supported in the separate module > 'ignite-spring-data_2.0' > * Added monitoring of critical system workers > * Added ability to provide custom implementations of ExceptionListener for > JmsStreamer > * Ignite KafkaStreamer was upgraded to use new KafkaConsmer configuration > * S3 IP Finder now supports subfolder usage instead of bucket root > * Improved dynamic cache start speed > * Improved checkpoint performance by decreasing mark duration. > * Added ability to manage compression level for compressed WAL archives. > * Added metrics for Entry Processor invocations. > * Added JMX metrics: ClusterMetricsMXBean.getTotalBaselineNodes and > ClusterMetricsMXBean.getActiveBaselineNodes > * Node uptime metric now includes days count > * Exposed info about thin client connections through JMX > * Introduced new system property IGNITE_REUSE_MEMORY_ON_DEACTIVATE to > enable reuse of allocated memory on node deactivation (disabled by default) > * Optimistic transaction now will be properly rolled back if waiting too > long for a new topology on remap > * ScanQuery with setLocal flag now checks if the partition is actually > present on local node > * Improved cluster behaviour when a left node does not cause partition > affinity assignment changes > * Interrupting user thread during partition initialization will no longer > cause node to stop > * Fixed problem when partition lost event was not triggered if multiple > nodes left cluster > * Fixed massive node drop from the cluster on temporary network issues > * Fixed service redeployment on cluster reactivation > * Fixed client node stability under ZooKeeper discovery > * Massive performance and stability improvements > > Ignite .Net: > * Add .NET Core 2.1 support > * Added thin client connection failover > > Ignite C++: > * Implemented Thin Client with base cache operations > * Implemented smart affinity routing for Thin Client to send requests > directly to nodes containing data when possible > * Added Clang compiler support > > SQL: > * Added experimental support for fully ACID transactional SQL with the > snapshot isolation: > - use CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT to enable it > - a transaction can be started through native API (IgniteTransactions), > thin JDBC driver or ODBC driver > - not production ready, data consistency is not guaranteed in case of > node failures > * Added a set of system views located in "IGNITE" schema to view cluster > information (NODES, NODE_ATTRIBUTES, NODE_METRICS, BASELINE_NODES) > * Added ability to create predefined SQL schemas > * Added GROUP_CONCAT function support > * Added string length constraint > * Custom Java objects are now inlined into primary and secondary indexes > what may significantly improve performance when AFFINITY_KEY is used > * Added timeout to fail query execution in case it cannot be mapped to > topology > * Restricted number of cores allocated for CREATE INDEX by default to 4 to > avoid contention on index tree Fixed transaction hanging during runtime > error on commit. > * Fixed possible memory leak when result set size is multiple of the page > size > * Fixed situation when data may be returned from cache partitions in LOST > state even when PartitionLossPolicy doesn't permit it > * Fixed "Caches have distinct sets of data nodes" during SQL JOIN query > execution between REPLICATED and PARTITIONED caches > * Fixed wrong result for SQL queries when item size exceeds the page size > * Fixed error during SQL query from client node with the local flag set to > "true" > * Fixed handling UUID as a column type > > JDBC: > * Implemented DataSource interface for the thin driver > > ODBC: > * Added streaming mode support > * Fixed crash in Linux when there are more than 1023 open file descriptors > * Fixed bug that prevented cursors on a server from being closed > * Fixed segmentation fault when reusing a closed connection > > Web Console: > * Added new metrics: WAL and Data size on disk > * Added support for "collocated" query mode on Query screen > * Added support for Java 9+ for Web Agent. > * Added ability to show/hide password field value > * Implemented execution of selected part of SQL query > * Implemented explain of the selected part of SQL query > * Implemented connection to a secured cluster > * Implemented responsive full-screen layout > * Split "Sign In" page to three separate pages > * UI updated to modern look and feel > * Improved backend stability > * Fixed fail when working with web sockets > > REST: > * Added option IGNITE_REST_GETALL_AS_ARRAY for array format in "getAll" > call > > Visor: > * Added output of node "Consistent ID" > * Visor now collects information about cache groups instead of separate > caches to reduce memory consumption > * Improved help for "start" command > * Fixed output of cache metrics > > Control utility: > * Added information about transaction start time > * Added command to collect information about a distribution of partitions > * Added command to reset lost partitions > * Added support for empty label (control.sh --tx label null) > * Added atomicity mode to utility output. > * Added orphaned local and remote transactions and ability to rollback them > * Added "--dump" flag to dump current partition state to file. > * Renamed command argument
