Subject [jira] [Created] (CASSANDRA-11048) JSON queries are not thread safe
Date Wed, 20 Jan 2016 17:41:39 GMT
Sergio Bossa created CASSANDRA-11048:
----------------------------------------

             Summary: JSON queries are not thread safe
                 Key: CASSANDRA-11048
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11048
             Project: Cassandra
          Issue Type: Bug
            Reporter: Sergio Bossa
            Priority: Critical


{{org.apache.cassandra.cql3.Json}} uses a shared instance of {{JsonStringEncoder}} which is
not thread safe (see 1), while {{JsonStringEncoder#getInstance()}} should be used (see 2).

As a consequence, concurrent {{select JSON}} queries often produce wrong (sometimes unreadable)
results.
