Subject [jira] [Commented] (CASSANDRA-9921) Combine MV schema definition with MV table definition
Date Mon, 10 Aug 2015 15:44:46 GMT


Carl Yeksigian commented on CASSANDRA-9921:

Right now we're storing all of the columns in the {{Schema.materialized_views}} table, because
we don't use {{Schema.columns}} when initializing the MV. This means that we have a copy of
the column definitions (Primary, Clustering, and "Included") in the MV definition, and we
also have them in {{Schema.columns}}. We can remove that duplication, since all of the information
we'd be using is already included in columns, except for whether this was a {{SELECT *}} query
or not. That additional piece of information can be captured more succinctly as a boolean
(includeAll) on the MV schema table.

the {{system_schema.materializedviews}} table to keep them separate entities.
