------------------------------------------
Summary: Calcite engine. Memory leak in RelOptCluster during
mapping
Key: IGNITE-16354
URL: https://issues.apache.org/jira/browse/IGNITE-16354
Project: Ignite
Issue Type: Bug
Reporter: Aleksey Plekhanov
The static instance of {{RelOptCluster}} accumulates data in the cache
(\{{BaseQueryContext.CLUSTER.mq.map}}) and never clear it. We should attach the
new cluster query fragments during each mapping and detach it before storing
the query plan in the query plan cache.
