Stefan Miklosovic commented on CASSANDRA-20827:
-----------------------------------------------
[~mrktsm] I think it still makes sense to at least expose maps as JSONs. It
still has a value. We do not need to be so pedantic about it. Would you mind to
rebase your patch on top of the current trunk at least? There were changes done
related to this code after CASSANDRA-20856.

> Key: CASSANDRA-20827
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20827
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Local/Config
> Reporter: Paulo Motta
> Assignee: Marko Tsymbaliuk
> Priority: Normal
> Time Spent: 40m
> Remaining Estimate: 0h

> Complex configuration (maps/sets/lists) are represented as
> Collections.toString() on {{system.settings}} virtual table:
> {code:java}
> cqlsh> select * from system_views.settings where name='seed_provider' ;
> name | value
> ------+-------
> (0 rows)
> cqlsh> select * from system_views.settings where
> name='seed_provider.parameters' ;
> name | value
> --------------------------+------------------------
> seed_provider.parameters | {seeds=127.0.0.1:7000}
> {code}
> While this is fine for human consumption, it's not ideal for programmatic
> access, since it requires custom parsing.
> This ticket is to add ability of representing complex types as JSON on
> {{system.settings}} and potentially making it default in trunk, so the above
> would return:
> {code:java}
> cqlsh> select * from system_views.settings where name='seed_provider' ;
> name | value
> ------+-------
> (0 rows)
> cqlsh> select * from system_views.settings where
> name='seed_provider.parameters' ;
> name | value
> --------------------------+------------------------
> seed_provider.parameters | {"seeds": "127.0.0.1:7000"}{code}
