> Java thin: avoid buffer copies in synchronous operations
> --------------------------------------------------------
>
> Key: IGNITE-13804
> URL: https://issues.apache.org/jira/browse/IGNITE-13804
> Project: Ignite
> Issue Type: Improvement
> Components: thin client
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Minor
>
> {{org.apache.ignite.internal.client.thin.TcpClientChannel#send}} creates a
> buffer copy, because the buffer will be returned to the pool upon leaving the
> scope, but we need it to survive longer while NIO framework processes it.
> However, for synchronous requests we block the thread anyway, so an extra
> copy can be avoided. See discussion in
> [#8483|https://github.com/apache/ignite/pull/8483#discussion_r533915757]
