> DistributedMetastorage functionality introduced in IGNITE-10640 provides convenient way to perform coordinated writes to local MetaStorages on all server nodes but lacks important part: validation of key length.
> Current implementation of MetaStorage doesn't allow keys longer than a specific value (64 bytes minus some prefixes, see source code for details) and throws assertion error on an attempt to write longer key.
> This error from MetaStorage is not propagated to DistributedMetastorage and (in theory) may even cause a node to halt.
> In order to avoid this situation validation of key length should be added right to DistributedMetastorage implementation to enforce "fail-fast" principle and preserve Ignite nodes from potentially dangerous consequences.
