Today, etcdctl endpoint health only performs a quorum GET. If server is corrupted or exceeded quota (which put the server into read only mode), this command incorrectly returns healthy.

Index constraint generation currently supports constraints from LIKE expressions, but the opt statistics code does not. A simple improvement would be to handle the case where the expression is exactly equivalent to a range of values.

Note that such a rule would need to handle escaping correctly (which the index constraints code currently does not, see #44123).

The module shardingsphere-shadow-spring-boot-starter is missing test cases.
Please add test case for spring boot starter.

Now insert and query share the resource ( Max Process Count control) 。 When the query with high TPS，the insert will get error (“error: too many process”). I think separator the resource for Insert and Query will makes sense. Ensure enough resource for insert。It looks like Use Yarn， Insert and Query use the different resource quota。
Or the simple way , Can we set Ratio for Insert and

From discussion with @brownleej , it's better to rename it to avoid confusion with fdbrestore (from the old restore) and with backupAgent.

This should have no functional change.

Hello Philip!
I think there is an issue with this part of the code of rqlite (store/store.go).

func (s *Store) Database(leader bool) ([]byte, error) {
	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
	}
	// Ensure only one snapshot can take place at once, and block all queries.
	s.mu.Lock()
	defer s.mu.Unlock()

	f, err := ioutil.TempFile("", "rqlilte-snap-

Currently the release_version column exists in the system.peers table and has the right type, but the value is not being set when producing the result for queries. Therefore its value is always returned as null.

Example

Start a cluster locally with:

./bin/yb-ctl create --rf 3

Connect with ycqlsh

./bin/ycqlsh

Check release version in system.l

Currently, Stats command in the protocol and olric-stats tool only work on a cluster member. So if you run the following command:

olric-stats -a=cluster-member:port

It returns statistics for only one cluster member. This is not very useful most of the time. We need to aggregate all statistics.

-s/--summary would also be useful.

SELECT custkey, sum(totalprice)
FROM orders
GROUP BY custkey
ORDER BY 2 DESC

Now that we support more than 1 data type, we should include the values data type in cache nodes. This give us a way of easily identifying what type of data a key points to e.g. string, queue (and more types in the future)

Currently a cache node object consists of a Key, a Value and a TTL. We should also add a field specifying the type of the Value
