Benedict Elliott Smith commented on CASSANDRA-17044:
----------------------------------------------------

This patch [introduced a minor performance regression to schema lookups|https://github.com/apache/cassandra/blob/2e680a33c03ce66d4b1358e1a1cc11cf4ee0189f/src/java/org/apache/cassandra/schema/Schema.java#L323], which affects query parsing, by invoking {{distributedAndLocalKeyspaces}} in a lookup method, which involves building a new map before finding an element.

> The idea is decompose `Schema` into separate entities responsible for different things. In particular extract what is related to schema storage and synchronization into a separate class so that it is possible to create an extension point there and store schema in a different way than `system_schema` keyspace, for example in etcd. 
> This would also simplify the logic and reduce the number of special cases, make all the things more testable and the logic of internal classes encapsulated.
