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.
