---------------------------------
Summary: 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.
