> Thread contention accessing JsonProperties props
> ------------------------------------------------
>
> Key: AVRO-2051
> URL: https://issues.apache.org/jira/browse/AVRO-2051
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.2
> Reporter: Daniel Kulp
>
> See
> https://lists.apache.org/thread.html/dd34ab8439137a81a9de29ad4161f37b17638394cea0806765689976@%3Cuser.avro.apache.org%3E
> Basically, the getJsonProp method, being synchronized, is causing thread
> contention issues when trying to share schemas between threads. My
> proposal (pull request forthcoming) is to treat "props" as an immutable map
> and do a copy+add+swap for the addProp method. This will make the addProp
> call slower (particularly for large maps of props), but would make the reads
> significantly faster as no locking will be needed.
