Online docs provide very limited details on the SQL query semantics Dremio claims to support.
Makes it very hard to determine if a parser error is:
- bug
- design intent
- limitation
Not clear what constructs Dremio would claim to implement which only the Dremio engine implements versus those it will push.
Unclear where Dremio documents what SQL semantics it thinks it can correctly push to an external source (i.e. database).
