Apache Ignite Release Notes
|
||
|
|
===========================
|
||
|
|
|
||
|
|
Apache Ignite In-Memory Distributed Database 2.11.0
|
||
|
|
-----------------------------------------------------------
|
||
|
|
|
||
|
|
Ignite:
|
||
|
|
|
||
|
|
* Added the ability to restore cache groups from a snapshot on an active cluster by using the Java API or command line control script.
|
||
|
|
* Added the check snapshot procedure that validates snapshot consistency or individual cache groups.
|
||
|
|
* Added cluster metastorage to process of creating a snapshot.
|
||
|
|
* Added command to control.(sh|bin) that makes possible performance statistics management.
|
||
|
|
* Added clock and Segmented-LRU page replacement modes.
|
||
|
|
* Added node attribute collocated affinity backup filter.
|
||
|
|
* Added system views for data structures.
|
||
|
|
* Added system view for baseline node attributes.
|
||
|
|
* Added metrics for monitoring the number of memory pages related to SQL indexes. These metrics can be made available via JMX and viewed as part of data region and cache group properties under the name `InMemoryIndexPages`.
|
||
|
|
* Added metrics for the number of written and compressed bytes for WAL.
|
||
|
|
* Added SSL connection metrics.
|
||
|
|
* Added list of indices that will not be rebuilt forcibly to control.sh utility output.
|
||
|
|
* Added the argument "pages" to the IgniteWalConverter for searching pages in the WAL.
|
||
|
|
* Added support for IGNITE_ENABLE_FORCIBLE_NODE_KILL flag in inverse connection protocol.
|
||
|
|
* Added property `checkpoint.deviation` for randomization of checkpoint interval. It sets the checkpoint frequency in per cent via control.sh utility: `control.sh --property set --name checkpoint.deviation --val 25`.
|
||
|
|
* Added support of Spring Data repositories initialisation with Spring Boot auto-starter.
|
||
|
|
* Fixed incorrect values of cache, cache group, data region metrics after cluster re-activation.
|
||
|
|
* Fixed error with nodes fallabck. Now nodes will properly fallback to full rebalance if historical rebalance fails.
|
||
|
|
* Fixed possible deadlock in concurrent cache data store initialization, exchange initialization and start of checkpoint.
|
||
|
|
* Fixed potential JVM crash due to integer overflow in binary streams.
|
||
|
|
* Fixed node fail due to deleting DurableBackgroundTask's at the end of a checkpoint when stopping a node.
|
||
|
|
* Fixed an issue causing omitting of NOT NULL constraint validation for columns that are part of compound primary key.
|
||
|
|
* Fixed an issue causing an error on modification binary object that contains reference to its own inner collection (binary HANDLE to collection).
|
||
|
|
* Fixed an issue where exception in static initializer during remote filter deployment could lead to the server node failure.
|
||
|
|
* Fixed deploying of continuous queries. They won't be deployed to the client nodes, since the clients don't store any data.
|
||
|
|
* Fixed behaviour while writing to Distributed Metastorage. Now exception is thrown on client if client is not connected to topology.
|
||
|
|
* Fixed node failure when a class was not found by UriDeploymentSpi.
|
||
|
|
* Fixed an issue causing corruption of PK index tree in case the table was created via SQL API and the PK has several fields in order different from those specified in thr field list.
|
||
|
|
* Fixed failure to connect to node leading to freezing connection future if paired connections are used.
|
||
|
|
* Fixed possible index partition corruption after drop index with failed checkpoint scenario.
|
||
|
|
* Fixed cache group re-encryption after cluster secondary activation.
|
||
|
|
* Fixed an issue that led to the fact that baseline auto adjustment was not triggered under certain conditions.
|
||
|
|
* Fixed the race between auto rollover segments and WAL deactivation.
|
||
|
|
* Fixed an issue when Data Streamer flushing could freeze due to a connectivity problem.
|
||
|
|
* Fixed an issue that prevented a node from startup in case it can't obtain IP addresses to connect to.
|
||
|
|
* Fixed the ability to force rebuild indexes for caches.
|
||
|
|
* Fixed rebuilding indexes. Synchronously stop rebuilding indexes when the cache is stopped to avoid a node fail.
|
||
|
|
* Fixed a corner case when a node could ignore an OutOfMemoryError and fail to stop.
|
||
|
|
* Fixed merge query with no unique colons for the Oracle dialect.
|
||
|
|
* Fixed an issue when connection closed by the one node could lead to infinite connection attempts on the other node.
|
||
|
|
* Fixed (decreased) an exclusive checkpoint lock time.
|
||
|
|
* Fixed issue, when CPU checkpoint pool size is not initialized.
|
||
|
|
* Fixed NullPointerException when run out automatic segment archiving after last record logging.

||
|
|

|
||
|
|
* Fixed restart rebuild indexes, if they were not rebuilt, on node restart / reactivation.
|
||
|
