Spanner DML Statements Now Enforce 80K Mutation Limit Per Statement

Google Cloud Spanner now enforces its 80,000 mutation limit for DML statements on a per-statement basis, rather than cumulatively across an entire transaction. This enhancement provides greater flexibility, enabling transactions to include multiple DML statements that might collectively surpass the old cumulative limit, provided each individual statement adheres to the 80,000 mutation cap. The change primarily affects developers and database administrators executing complex DML operations in Spanner. For the Mutation API, the 80,000 limit still applies to all mutations within a commit, and all transactions remain subject to a 100 MiB commit size limit.
