Ignite TC Bot commented on IGNITE-28895:
----------------------------------------
I prepared the minimal documentation patch locally against
docs/_docs/SQL/sql-calcite.adoc on branch IGNITE-28895-docs.
The local patch documents Calcite SQL window functions in the Supported
Functions section: OVER, PARTITION BY, ORDER BY, ROWS/RANGE frames, aggregate
window functions, ROW_NUMBER, RANK, DENSE_RANK, PERCENT_RANK, CUME_DIST, LAG,
LEAD, and FIRST_VALUE.
Public PR creation is blocked in this run: git push to the configured fork
ignitetcbot/ignite returned HTTP 403, and the GitHub integration cannot create
a branch in apache/ignite (Resource not accessible by integration). Keeping
this documentation issue open until a maintainer or an account with push
permission publishes the patch.
