Strong consistent requests take different patch then EC requests and consistency levels don’t map well. We should limit available consistency levels in SC request to avoid ignoring them silently, which may cause confusion to user. For writes, there is only one option: - QUORUM/LOCAL_QUORUM (multi DC is not supported yet, so both of those CLs have the same effect) - we need quorum of replicas to successfully commit new mutations to Raft log. For reads, there are 2 options: - QUORUM/LOCAL_QUORUM - if user wants to be sure he sees latest data and the query needs to execute `read_barrier()`, which requires quorum of replicas - ONE/LOCAL_ONE - if user just wants to read data from one replica without synchronization All tests were updated to use LOCAL_QUORUM for both read and writes. Fixes SCYLLADB-1766 SC is in experimental phase and this patch is an improvement, no backport needed. Closes scylladb/scylladb#29691 * github.com:scylladb/scylladb: strong_consistency: allow QUORUM/LOCAL_QUORUM and ONE/LOCAL_ONE for reads strong_consistency: allow only QUORUM/LOCAL_QUORUM CL for writes

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
