Summary: SQL: review security check for SQL/DML queries
Key: IGNITE-11712
URL: https://issues.apache.org/jira/browse/IGNITE-11712
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Roman Kondakov
Currently the security check (read/write permissions) is carried out during the
query execution. It involves some extra actions (like a query registration)
which can be avoided if the security check is conducted on the earlier stage of
the query execution, for example right away after the parsing.
For SELECT queries only read permission should be checked.
For INSERT queries without SELECT only write permission should be checked.
For UPDATE queries or INSERT queries with SELECT both read and write
permissions should be checked.
