Subject [jira] [Commented] (CASSANDRA-9367) Expose builtin-in CQL functions via schema data dictionary
Date Sun, 14 Jun 2015 08:49:00 GMT


Robert Stupp commented on CASSANDRA-9367:

Note for later: some functions (TOKEN, TO_JSON/FROM_JSON, COUNT) are special cased and not
"declared" internally - so querying {{Functions.declared}} might not be sufficient to get
all native functions.

for the current {{system.schema_functions}} table, to avoid creating a special case just for

> Builtin CQL functions are not described in the {{system}} keyspace in its current representation,
this new schema should include them next to the user defined ones as:
> * The {{system}} keyspace and its tables are described in the {{system}} keyspace, therefore
it would be consistent.
> * Having builtin CQL functions described there would allow external tools to manipulate
all the functions in a similar way.
> * This would document the available builtin function for users that don't remember the
ones available in their current version of Cassandra.
