----------------------------------------
Summary: SQL: Explicit and extracted partitions should be merged
through AND semantics
Key: IGNITE-10567
URL: https://issues.apache.org/jira/browse/IGNITE-10567
Project: Ignite
Issue Type: Task
Components: sql
Reporter: Vladimir Ozerov
See {{IgniteH2Indexing.doRunDistributedQuery}}. Currently we process explicit
and extracted partitions as follows:
# If explicit partitions are set, then use them
# Otherwise use extracted partitions if available
Now consider that explicit partitions are set to {{A, B}} and extracted
partitions are {{B, C}}. Currently we will execute query over {{A, B}}, while
in reality it seems that we can execute it only on {{B}} (intersection).
In extreme case intersection will be an empty set, so query execution might be
skipped altogether.
