Hi folks, Iceberg-cpp 0.3.0 was released in June. Since then, 174 commits have landed on main, including several key features and enhancements:
- Iceberg v3: Support for new types (timestamp_ns, timestamptz_ns, unknown, geometry, geography), column default values, binary deletion vectors, and row lineage. - Table updates: MergeAppend, DeleteFiles, RowDelta, OverwriteFiles, RewriteFiles, and ReplacePartitions. - Performance: Parallel manifest reads and writes, lazy scan planning, an LRU cache, and metrics for commits and scans. - Catalogs and IO: REST SigV4 and OAuth2 token exchange, vended credentials, an initial Hive Metastore client, and ResolvingFileIO. - Other updates: Pluggable logging (optional spdlog backend) and metadata table scans (SnapshotsTable). Meson build support has been removed. Given this progress, I would like to propose starting the 0.4.0 release. Ongoing work, such as variant types, encryption, and Puffin statistics, will be deferred to a later release. Please let me know your thoughts. If there are no objections, I am happy to act as the release manager, with Gang Wu kindly offering support. Thanks, Manu
