Daniel Kulp created AVRO-2051: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
