------------------------------------------
Summary: Support a map of counters
Key: CASSANDRA-13003
URL: https://issues.apache.org/jira/browse/CASSANDRA-13003
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Andrew Voumard
Priority: Minor
Would it be possible to support the dynamic addition of counters, by supporting
a map of counters ? This would make it easier to support situations where
counters could be added more dynamically (where their names are not known at
design time).
If it makes it any easier, I would expect it to be ok if the current
restriction of not being able to delete a counter remains, meaning requests to
remove an item from the map would be ignored or return an error.
I expect it would be possible to synthesize this feature without impacting the
core code, by dynamically adding counter columns via dynamic schema ALTER
statements, creating something like <map_name>-<counter_name> columns on
demand, effectively wrapping the dynamic column addition, but native cql
support would make this task simpler.
