-------------------------------------------
Summary: Make partition awareness approach available with calcite
engine
Key: IGNITE-29242
URL: https://issues.apache.org/jira/browse/IGNITE-29242
Project: Ignite
Issue Type: Improvement
Components: sql
Affects Versions: 2.19
Reporter: Evgeny Stanilovsky
Currently partiton awareness (affinityAwareness - old name) approach was
implemented during [1]. This technique makes the JDBC driver "aware" of the
partition distribution in the cluster.
It allows the driver to pick the nodes that own the data that is being queried
and send the query directly to those nodes
(if the addresses of the nodes are provided in the driver's configuration).
Partition awareness can increase average
performance of queries that use the affinity key.
Also need pick up [2] activity and fill some performance tests probably in
different issue.
