Summary: Add SystemProperty for H2Connection#STATEMENT_CACHE_SIZE
Key: IGNITE-20061
URL: https://issues.apache.org/jira/browse/IGNITE-20061
Project: Ignite
Issue Type: Improvement
Components: h2-limitation, jdbc
Affects Versions: 2.15
Reporter: asdfgh19
We cache SQL statements in H2Connection. Although we can periodically clean up
the entire H2StatementCache by configuring
IGNITE_H2_INDEXING_CACHE_CLEANUP_PERIOD , a single statement cannot be cleared
individually when the connection continues to query.
When the memory is sufficient, we hope to increase the size of H2StatementCache
to improve performance;
When the memory is limited, we hope to reduce the size of H2StatementCache to
avoid memory overflow;
So I propose to add a system property
IGNITE_H2_INDEXING_CACHE_STATEMENT_CACHE_SIZE to configure the H2StatementCache
size.
