> URL: https://issues.apache.org/jira/browse/CASSANDRA-10680
> Project: Cassandra
> Issue Type: Bug

> Fix For: 3.0.1, 3.1, 2.1.x, 2.2.x
>
>
> For clusters using small compression chunk size and terabytes of data, the
> streaming plan calculations will instantiate hundreds of millions of
> compressionmetadata$chunk objects, which will create unreasonable amounts of
> heap pressure. Rather than instantiating all of those at once, streaming
> should instantiate only as many as needed for a single file per table at a
> time.
