Support for COMMENT ON for tables, table columns, and databases was implemented in 2019 for cockroachdb/cockroach#19472 then the issue was closed by @jordanlewis because schemas were not s

Hi,
I found a documentation error.

ext-lib are right, lib-ext are not right. it ’s need correction.

fdbcli flags currently contain a mixture of _ and - (probably for historic reasons). I would propose to unify the flags and only use either _ or - personally I tend to hyphens like recommended in the POSXI standard (https://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html). Current fdbcli help output:

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-

This is admittedly a problem that bothers us in internal portal usage more than real customers (who tend not to have so many db versions)

When there's many db versions available to YW, the default db software version in Create Universe flow (first version in the list below) seems to be based on sort order. Instead we should default the DB version to the same as the current Platform version (in

In the past a conversion through Number "interface" has proven to be able to mask bugs in the code.
We should remove these conversions from io.trino.spi.type.TypeUtils#writeNativeValue.

Use case:

1.) A user may want to backup all tables but no metadata like users, privileges, etc. without explicitly defining each table inside the CREATE SNAPSHOT statement.

2.) A user may want to transfer users & privileges, custom analyzers or user-defined-functions from one cluster to another without backing up a complete cluster including all data (tables).

*Feature description

Currently we don't have any mechanism to limit the maximum number of clients that could be handled simultaneously.

This feature should be designed properly. Here is some clue: https://redis.io/topics/clients#maximum-number-of-clients

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
