# Proposed changes
This pr added support for the pre-aggregation hint. Users could use
`/*+PREAGGOPEN*/` to enable pre-preaggregation for OLAP table.
For example:
Let's say we have an aggregate-keys table t (k1 int, k2 int, v1 int sum, v2
int sum). Pre-aggregation could be enabled by query with a hint: `select k1, v1
from t /*+ PREAGGOPEN*/`.
