Description

John Blum opened DATACASS-273 and commented

Both the CassandraTemplate and CqlTemplate make use of the Template design pattern with anonymous callbacks (temporary objects) that, when called under load, can reck havoc on the JVM garbage collection process, especially in an embedded context. Review the use of callbacks and minimize where possible without sacrificing maintainability

Affects: 1.4.1 (Hopper SR1)
