> Key: JAMES-2897
> URL: https://issues.apache.org/jira/browse/JAMES-2897
> Project: James Server
> Issue Type: Bug
> Components: cassandra
> Reporter: Matthieu Baechler
> Priority: Major
>
> After reading https://docs.datastax.com/en/ddac/doc/datastax_enterprise/dbInternals/dbIntLtwtTransactions.html , https://docs.datastax.com/en/ddaccql/doc/cql/cql_reference/cqlsh_commands/cqlshConsistency.html and https://docs.datastax.com/en/ddaccql/doc/cql/cql_reference/cqlsh_commands/cqlshSerialConsistency.html It looks like we should be more careful about consistency when reading tables that use LWT.
> Basically, to ensure we always read the last value, we must read with SERIAL consistency.
