Matthieu Baechler commented on JAMES-3224:
------------------------------------------
I feel it's quite dangerous to do that: the application knows better than the
user which consistency level to use for things.
What we can do is allow to switch QUORUM-style queries to EACH_QUORUM or
LOCAL_QUORUM but it would not make sense to allow for ONE for example
BTW, we also have, in the codebase, some ONE on specific uses: we can't have a
single level of configuration as it uses ONE for good reasons.
> Make Cassandra Consistency levels configurable

> Key: JAMES-3224
> URL: https://issues.apache.org/jira/browse/JAMES-3224
> Project: James Server
> Issue Type: Improvement
> Components: cassandra
> Reporter: Gautier DI FOLCO
> Priority: Minor
>
> 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)
