----------------------------------
Resolution: Fixed
> [proton-j] FrameWriter allocates additional buffer capacity inefficiently
> -------------------------------------------------------------------------
>
> Key: PROTON-1808
> URL: https://issues.apache.org/jira/browse/PROTON-1808
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-j
> Affects Versions: proton-j-0.26.0
> Reporter: Timothy Bish
> Assignee: Timothy Bish
> Priority: Minor
> Fix For: proton-j-0.27.0
>
>
> When writing a Transfer that has a larger payload than previously seen the
> FrameWriter may need to grow its internal buffer to accommodate that
> transfer. The current strategy is to double the capacity of the current
> buffer and copy the old bytes into the new buffer and then check again if
> there is room. Depending on the frame size setting and the size of the
> transfer this can result in a large amount of garbage being created and a
> number of unneeded copies of encoded performative data.
