Yong Jiang commented on CASSANDRA-18177:
----------------------------------------
Hi, [~maxwellguo], I have implemented the toJsonString method for
AbstractCompositeType per your instruction. Since your change is planned for
5.0 release and not in current trunk yet, so I created new branch
CASSANDRA-18177-4.1 and merged the fixes from your branch CASSANDRA-17698-4.1.
So here is commited change for parsing index table for composite partition key.
Please help review and let me know your comments. If everything looks good, I
will go ahead make the changes for branches 3.0, 3.11, 4.0 and trunck as well
to match your changes.

I have also tried to created and parse an example table and below is the output
for your reference:
