zhjwpku opened a new issue, #637: URL: https://github.com/apache/iceberg-cpp/issues/637
We already have **partial support for Iceberg v3** in the codebase (e.g., Row Lineage and partition statistics). However, a number of key v3 features are still missing. This issue serves as a **parent tracking issue** for the remaining v3 work we plan to (partially) include in the **0.3.0 release**. If you are interested in working on any of the items below, please **open a dedicated sub-issue** and link it back to this one. ### 1. Schema-Level Support for New v3 Types Add support for all newly introduced v3 types at the schema level, including: * `timestamp_ns`, `timestamptz_ns` * `unknown` * `variant` * `geometry`, `geography` ### 2. Column Default Values (Schema Evolution) Enable schema evolution with default values: * Support `initial-default` and `write-default` * Apply defaults correctly during read and write paths ### 3. Multi-Argument Transforms Upgrade partitioning and sort order logic to support multi-column transforms: * Extend transform representation * Update parsing and validation logic ### 4. Binary Deletion Vectors Add support for deletion vectors (DV): * Puffin-based DV parsing * Scan-time application of DV * Writer-side support for generating DV ### 5. Table-Level Encryption Metadata (Not sure whether this should be included in 0.3.0) Support encryption-related metadata defined in v3: * Parse and preserve encryption metadata ### 6. Puffin-Based Statistics Support table and partition statistics stored in Puffin files: * Metadata parsing * Optional integration into scan planning If anything is missing or you have suggestions, feel free to comment or open additional sub-issues. -- This is an automated message from the Apache Git Service.
