Denis Magda created IGNITE-3090: ----------------------------------- Summary: Memory leak in IgniteH2Indexing prepared statements cache Key: IGNITE-3090 URL: https://issues.apache.org/jira/browse/IGNITE-3090 Project: Ignite Issue Type: Bug Affects Versions: 1.5.0.final Reporter: Denis Magda Fix For: 1.6
IgniteH2Indexing caches prepared statements in {{stmtCache}} that uses Threads as keys. Under they high load when there are many Threads the cache can grow significantly. Plus if a Thread is terminated its prepared statements are not get cleaned introducing a memory leak. A special background Thread should be introduced that will iterate over {{stmCache}} performing the following: - cleaning records for terminated Threads; - cleaning records of the Threads that were not used for a long time. A special configuration parameter can be set. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
