Summary: Optimize count of threads for rebuild indexes Key: IGNITE-12684 URL: https://issues.apache.org/jira/browse/IGNITE-12684 Project: Ignite Issue Type: Improvement Reporter: Kirill Tkalenko Assignee: Kirill Tkalenko Fix For: 2.9 We were recently implemented the new property {{INDEX_REBUILDING_PARALLELISM}} (by issue IGNITE-11979). That fix do possible to rebuild indexes, after restart without index.bin or restore from snapshot to another topology, in parallel threads. But now the process of rebuild can to consume a lot of threads, which limited on INDEX_REBUILDING_PARALLELISM * AVAILABLE_PROC_CNT (count of thread in public pool). For example in case of INDEX_REBUILDING_PARALLELISM = 28 and 64 CPU it will be more then 1.5К threads. Look at the method, it will create dedicate thread on each invocation `org.apache.ignite.internal.processors.query.schema.SchemaIndexCacheVisitorImpl#processPartitionsAsync` -- This message was sent by Atlassian Jira (v8.3.4#803005)
