commit 4a00013b0fe76ffd30a57752e54b5dcea7371fa7 Author: Socrates <[email protected]> AuthorDate: Tue May 19 18:03:28 2026 +0800 [fix](paimon) Pin snapshot ID for Paimon external table queries to avoid compaction issues Doris previously used an unpinned Paimon table handle for normal queries, relying on the Paimon SDK to discover the latest snapshot. This could lead to empty results if a compaction occurred during the query, as the SDK might fail to resolve the new snapshot correctly. This change modifies PaimonExternalTable to always use the pinned table from the snapshot cache, ensuring consistency across all query types (Normal, MTMV, and MVCC).
