Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

Currently, tree.NotExpr is implemented natively in the vectorized engine, so we have to fallback to the older row-by-row engine to evaluate it. We should, instead, vectorize NotExpr.

I think the implementation will be quite similar to how tree.IsNullExpr implemented, and I think we will want to implement two version of NotExpr operator:

  • one for projections, which populates a `coldata

Environment

Knex version: 0.21.1

Describe the bug
Using a time dimension on a runningTotal measure on Snowflake mixes quoted and unquoted columns in the query. This fails the query, because Snowflake has specific rules about quoted columns. Specifically:

  • All unquoted column names are treated as upper case
  • Quoted column names are case sensitive.

So "date_from" <> date_from

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-
