> Currently ReplicationConfigValidator does not validate EC related configuration properly, as ECReplicationConfig is missing the toString method required by the validator.
> Also at the moment ECReplicationConfig's String based constructor does enable weird configs like 2 data and 6 parity blocks with a chunk size of 177.
> I think we should be and can be more prescriptive, and allow only the supported configs in EcReplicationConfig, with the supported data-parity pairs, and chunk size divisible by 1KiB, and maximize it at 1024KiB, which in a 10-4 setup already means 14MB buffered data on the client side. These might be adjusted at will, or later if we think it is better to have bigger sizes, but I think initially these are good boundaries.
