mcs, tso: change keyspace group primary path. #6526

binshi-bing · 2023-05-26T09:02:56Z

What problem does this PR solve?

Issue Number: Ref #5895

We need to add watch loop to every TSO server to watch the primaries of all keyspace groups. When #TSOServers > #GroupReplica, a TSO server only owns replicas of part of keyspace groups, i.e., the TSO server doesn't know the primaries of keyspace groups that the TSO server doesn't own. The partial keyspace group state view leads to slow TSO service discovery and inconsistent membership view.
The above watch loop needs to watch the range [/ms/{cluster_id}/tso/00000/primary, /ms/{cluster_id}/tso/99999/primary], but it overlaps with keyspace groups' timestamp path /ms/{cluster_id}/tso/{group}/{gta|lta}/.../timestamp which results in huge inefficiency (as far as I know, there is no built-in filter based on suffix).

Why do we keep the same path for Default keyspace group?
It has been deployed to prod, and the change will cause incompatability issues. Leave the change and upgrade to the future.

What is changed and how does it work?

mcs, tso: change keyspace group primary path.

The path for non-default keyspace group primary election changes
from  "/ms/{cluster_id}/tso/{group}/primary" to "/ms/{cluster_id}/tso/keyspace_groups/election/{group}/primary".
Default keyspace group keeps /ms/{cluster_id}/tso/00000/primary.

pkg/storage/endpoint/key_path.go

-// ExtractKeyspaceGroupIDFromPath extracts keyspace group id from the given path, which contains
-// the pattern of `tso/keyspace_groups/membership/(\d{5})$`.
-func ExtractKeyspaceGroupIDFromPath(path string) (uint32, error) {
+// GetCompiledKeyspaceGroupIDRegexp returns the compiled regular expression for matching keyspace group id.


Why do we need to separate it into two functions?

performance concern. Compile the patten once and use it every time for matching to boost performance. It should save time for loading all the existing keyspace groups before starting watch loop, thus speed up server bootstrap.
