[10:37:32] lunch [13:34:19] \o [13:35:10] o/ [15:29:51] .o/ [15:31:34] o/ [15:55:05] heading out [16:00:26] randomly curious, semantic search p50s jumped from 170ms to 230ms at 10:50 today, wonder what changed [16:01:59] per SAL, at 10:58 one of the dse-k8s hosts went for reimaging. Timing lines up, but doesn't seem like it should be related [16:02:35] not a big deal, 230ms is still fine, just curious [16:56:56] ebernhardson interesting, I guess it behooves us to check and make sure the ureadahead was applied after the move. Let me check which pods are the newest [16:59:28] `opensearch-semantic-search-masters-5` and `opensearch-semantic-search-masters-6` are the newest, running on `dse-k8s-worker1013.eqiad.wmnet` and `dse-k8s-worker1028.eqiad.wmnet`, respectively. Let me check [16:59:44] oh i didn't think to check if a pod started at that time [17:04:00] `opensearch-semantic-search-masters-6` has the correct read_ahead [17:34:24] In a mtg for the next 90m, but I think we're good on that front [18:24:48] Looked closer into the archive search problem, it's not an easy fix :( The problem is we use the page id as the doc id in archive search. But really old logs don't always have a log_page, so they are missing. And pages can be delete->restore->move->delete, which generates two logs in two different namespaces for the same page id [18:25:23] plausibly the solution is to accept some duplication and use log_id as the docid, but that's a larger process [20:15:12] Looks like a PR landed for the x-request-id stuff: https://github.com/opensearch-project/OpenSearch/pull/21048
