> Key: CASSANDRA-15900
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15900
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Streaming and Messaging
> Reporter: ZhaoYang
> Assignee: ZhaoYang
> Priority: Normal
> Fix For: 4.0-beta
>
>
> CASSANDRA-15740 added the ability to stream entire sstable by loading on-disk
> file into user-space off-heap buffer when SSL is enabled, because netty
> doesn't support zero-copy with SSL.
> But there are two issues:
> # file channel is not closed.
> # 1mb batch size is used. 1mb exceeds buffer pool's max allocation size, thus
> it's all allocated outside the pool and will cause large amount of
> allocations.
>
> [Patch|https://github.com/apache/cassandra/pull/651]:
> # close file channel when the last batch is loaded into off-heap bytebuffer.
> # reduce the batch to 64kb which is more buffer pool friendly when streaming
> entire sstable with SSL.
