-----------------------------------------------
Summary: ColumnIdentifier object size wrong when tables are not
flushed
Key: CASSANDRA-13533
URL: https://issues.apache.org/jira/browse/CASSANDRA-13533
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Eduard Tudenhoefner
Assignee: Eduard Tudenhoefner
It turns out that the object size of {{ColumnIdentifier}} is wrong when
*cassandra.test.flush_local_schema_changes: false*. This looks like stuff is
being wrongly reused when no flush is happening.
We only noticed this because we were using the prepared stmt cache and noticed
that prepared statements would account for *1-6mb* when
*cassandra.test.flush_local_schema_changes: false*. With
*cassandra.test.flush_local_schema_changes: true* (which is the default) those
would be around *5000 bytes*.
Attached is a test that reproduces the problem and also a fix.
