Eduard Tudenhoefner updated CASSANDRA-13533:
--------------------------------------------
Since Version: 3.0.0
> 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.
