* Split queries into system and data queries * System queries are sequentially executed and generate separate transaction deltas * System transaction try locks for 100ms * last_commited_system_ts saved to DBMS durability * Replicating CREATE/DROP DATABASE * Sending a system snapshot if REPLICA behind * Passing a copy of the gatekeeper::access as std::any to all functions that could call an async execution * Removed delete_on_drop flag (we now always delete on drop) * Using UUID as the directory name for databases * DBMS durability update (added versioning and salient information) * Automatic migration from previous version * Interpreter can run some queries without a target database * SHOW REPLICA returns the status of the currently active DB * Returning UUID instead of db name in the RPC responses * Using UUIDs for database specification in RPC (not name) * FrequentCheck forces update on reconnect * TimestampRpc will detect if a replica is behind, and will update client's state * Safer SLK reads * Split SHOW DATABASES in two SHOW DATABASES (list of current databases) and SHOW DATABASE a single string naming the current database --------- Co-authored-by: Gareth Lloyd <gareth.lloyd@memgraph.io>
