| - **Queries that exceed memory limits returned `500`**: The HTTP query endpoints now return `429 Too Many Requests` when a query exhausts the DataFusion memory pool. Previously, they returned `500`. For CSV, JSON, and JSON Lines output, this applies when the query fails before it returns any rows. Some queries still return `500`, such as a query on a table that runs out of memory while deduplicating data. Enterprise already returned `429`. | ||
| - **Catalog deadlock when checking a deleted table**: Checking whether a table is deleted now takes the catalog lock once. Previously, a catalog change that arrived between its two reads could deadlock the catalog. | ||
| - **WAL plugins received values under the wrong column names**: Rows passed to a WAL trigger's plugin now use the column names of their own record batch. Previously, when a flush held batches with the same columns in a different order, later batches used the first batch's column names. | ||
| - **Shutdown hung while a processing engine plugin was stuck**: The server now exits within about 2 seconds after shutdown completes, even while a plugin is stuck in a blocking call. Previously, it waited for the plugin's thread forever. Enterprise already exited this way. |

What changed: Retain Phil's Core memory-error caveats and verified v3.12.2 source. Preserve the newer streaming-response distinctions and precise Enterprise wording from the target branch. Why: Keep the remaining corrections in Phil's contribution, PR #7961. Verification: Compared both PR heads and preserved the target branch content apart from the two Core caveats and the verified release-source comment.

Thanks @philjb! I'll merge the unique bits into 7957; there's some overlap with my earlier PR.

1d56d74a85). The v3.12.2 tag isf1972a0ff7: 3.12 at3aeb9c30plus influxdata/influxdb_pro#6990, so Use Cloud Dedicated admin UI to get started #6827 is not in it. It belongs in the next 3.12 patch. The HTML comment now names the tag instead of1d56d74a85.500..." Smoke tests of both Core builds with a small--exec-mem-pool-size: agenerate_seriesGROUP BY returned 429, but a GROUP BY on a table returned 500. The table query's memory error arrives wrapped (External(... 'deduplicate batches' ... ResourcesExhausted)), and the status mapping does not look insideExternal. Details on influxdata/influxdb_pro#6443.Not checked: whether Enterprise 3.12.2 / 3.11.8 return 429 for that table case, so "Enterprise already returned
429" is left as you wrote it.
