--------------------------------
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Avro Record Writer service creates byte buffer for every Writer created
> -----------------------------------------------------------------------
>
> Key: NIFI-5805
> URL: https://issues.apache.org/jira/browse/NIFI-5805
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
> Fix For: 1.9.0
>
>
> When we use the Avro RecordSet Writer, and do not embed the schema, the
> Writer uses the Avro BinaryEncoder object to serialize the data. This object
> can be initialized, but instead we create a new one for each writer. This
> results in creating a new 64 KB byte[] each time. When we are writing many
> records to a given FlowFile, this is not a big deal. However, when used in
> PublishKafkaRecord or similar processors, where a new writer must be created
> for every Record, this can have a very significant performance impact.
> An improvement would be to have the user configure the maximum number of
> BinaryEncoder objects to pool and then use a simple pooling mechanism to
> reuse these objects.
