From 7c5302daf33dcf251a239aad5c13a91cb0661ac6 Mon Sep 17 00:00:00 2001 From: Xinli Shang Date: Wed, 26 Nov 2025 09:07:55 -0800 Subject: [PATCH 1/4] feat: add SnapshotUpdate interface for snapshot-producing operations Add SnapshotUpdate interface that extends PendingUpdateTyped to provide common methods for all updates that create a new table snapshot. This follows the Java Iceberg API pattern where SnapshotUpdate provides a fluent API for operations like AppendFiles, DeleteFiles, and OverwriteFiles. Methods implemented: - Set(): Set summary properties on the snapshot - StageOnly(): Stage snapshot without updating table's current snapshot - DeleteWith(): Set custom file deletion callback for tracking or custom retention - ToBranch(): Commit snapshot to a specific branch (for WAP workflows) Method deferred: - ScanManifestsWith(): Deferred until executor/thread pool infrastructure is available in the codebase. Documented in class comments for future addition. Key features: - Uses CRTP pattern for type-safe fluent API and method chaining - Extends PendingUpdateTyped to inherit Apply() and Commit() - Protected members allow derived classes to access state - All methods return Derived& for method chaining Testing approach: - Tests verify behavior through public API only (Apply/Commit) - Avoids exposing internal state (no getter methods for protected members) - Mock implementation returns Snapshot with configured properties - 11 comprehensive test cases covering all methods and error paths This interface will be extended by concrete snapshot operations like: - AppendFiles: Add new data files to the table - DeleteFiles: Remove data files from the table - OverwriteFiles: Replace data files in the table - RewriteFiles: Compact and optimize data files --- src/iceberg/snapshot_update.h | 135 ++++++++++++++ src/iceberg/test/CMakeLists.txt | 1 + src/iceberg/test/snapshot_update_test.cc | 221 +++++++++++++++++++++++ src/iceberg/type_fwd.h | 2 + 4 files changed, 359 insertions(+) create mode 100644 src/iceberg/snapshot_update.h create mode 100644 src/iceberg/test/snapshot_update_test.cc diff --git a/src/iceberg/snapshot_update.h b/src/iceberg/snapshot_update.h new file mode 100644 index 000000000..ddbc4bc60 --- /dev/null +++ b/src/iceberg/snapshot_update.h @@ -0,0 +1,135 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
