Implement Materialized View GRACE PERIOD #15842

findepi · 2023-01-25T15:05:42Z

Description

Building on top of syntax added in #15104, fulfilling the important part of #15326, this PR delivers GRACE PERIOD support in the engine, exposing it to connectors and supporting it in Iceberg materialized views.

Additional context and related issues

Fixes #15326
Fixes #11698

Release notes

# General
* Support `GRACE PERIOD` clause in `CREATE MATERIALIZED VIEW` task.
  For backward compatibility, the existing materialized views are interpreted as
  having GRACE PERIOD of zero duration, however new materialized views have
  unlimited grace period by default. This is a backwards incompatible change and
  the previous behavior can temporarily be restored using
  `legacy.materialized-view-grace-period` configuration property or using
  `legacy_materialized_view_grace_period` session property.

# Iceberg
* Support materialized views with grace period defined.

Most predictable would be to cache freshness within a session and compare agains session start time.
But IDK if there are case when we compute the value within single sessions more than once. If not then it probably does not matter much.

i will leave this as is

thanks @losipiuk for you review.
Changes squashed directly since they are what you wanted them to be.
The only new code is Add Preconditions in io.trino.spi.connector package.
THere is one fixup which i mis-titled, so will force push once more.

Expose the GRACE PERIOD in `ConnectorMaterializedViewDefinition` so that connectors can store the information.

Let connector inform the engine how fresh the materialized view is. This is required to implement materialized view handling as per the new GRACE PERIOD syntax definition. Note: the property is called "last fresh time" and not "last refresh time". This is in support for connectors which know when view became no longer fresh. For example, a materialized view may have been refreshed a day ago, but only an hour ago one of its base tables changed. Then the materialized view is stale and "last fresh time" is one hour ago, not one day ago.
