Description

Consistency level in Cassandra queries is set explicitly to QUORUM in some cases, and to SERIAL in some other cases (lightweight transactions).

The goal is to make these queries globally configurable.

In the cassandra.properties file, I propose we add two configuration properties:

• cassandra.consistency_level.regular (default to QUORUM to avoid breaking changes)
• cassandra.consistency_level.lightweight_transaction (default to SERIAL)
