findinpath opened a new pull request, #18135:
URL: https://github.com/apache/iceberg/pull/18135
## What
Minimal, self-contained port of the materialized-view "storage table"
mechanism and its
RefreshState/SourceTableState/SourceViewState freshness/refresh bookkeeping
model onto the
stable apache-iceberg-1.11.0 release tag, instead of tracking main.
This branch carries just the storage-table/refresh-state-related files from
@wmoustafa's
materialized-views branch (which tracks main) — ViewVersion#storageTable(),
ViewBuilder#withStorageTableIdentifier(...), the corresponding wire-format
support in
ViewVersionParser/RESTSessionCatalog/CatalogHandlers, and the new
RefreshState /
RefreshStateParser / SourceState / SourceTableState / SourceViewState
classes — applied on top
of apache-iceberg-1.11.0, dropping everything else that branch picked up
incidentally from
tracking main (unrelated API churn, test adjustments, etc.).
## Why
Trino's Iceberg REST catalog materialized-view support (trinodb/trino#31027)
needs this native
mechanism to exist in a buildable Iceberg artifact. This branch exists so
that PR can build and
run its test suite against something closer to a real release than a full
main snapshot, while
the underlying spec/reference-implementation work is still unmerged upstream.
## Relationship to other PRs
- #9830 — the original reference implementation this is ported from
(materialized views backed
by a native storage table, with Spark integration).
- #11041 — the formal materialized-view spec proposal this mechanism is
based on.
This PR is not a proposal to merge materialized views into Iceberg — it's a
downstream
showcase/reference build for trinodb/trino#31027. Please treat #9830/#11041
as the actual venues
for that discussion.
