> Wrong size of cached prepared statements

> Key: CASSANDRA-8231
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8231
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jaroslav Kamenik
> Assignee: Benjamin Lerer
> Fix For: 2.1.3
>
> Attachments: 8231-notes.txt, CASSANDRA-8231-V2-trunk.txt,
> CASSANDRA-8231-V2.txt, CASSANDRA-8231.txt, Unsafes.java

>
> Cassandra counts memory footprint of prepared statements for caching
> purposes. It seems, that there is problem with some statements, ie
> SelectStatement. Even simple selects is counted as 100KB object, updates,
> deletes etc have few hundreds or thousands bytes. Result is that cache -
> QueryProcessor.preparedStatements - holds just fraction of statements..
> I dig a little into the code, and it seems that problem is in jamm in class
> MemoryMeter. It seems that if instance contains reference to class, it counts
> size of whole class too. SelectStatement references EnumSet through
> ResultSet.Metadata and EnumSet holds reference to Enum class...
