ESQL: Fix misspelling in generated docs (#129789) Pulled from #128576 so it's easier to review.
2025-06-21 03:42:37 +08:00
% This is generated by ESQL's AbstractFunctionTestCase. Do not edit it. See ../README.md for how to regenerate it.
ESQL autogenerate docs v3 (#124312) Building on the work started in https://github.com/elastic/elasticsearch/pull/123904, we now want to auto-generate most of the small subfiles from the ES|QL functions unit tests. This work also investigates any remaining discrepancies between the original asciidoc version and the new markdown, and tries to minimize differences so the docs do not look too different. The kibana json and markdown files are moved to a new location, and the operator docs are a little more generated than before (although still largely manual).

ESQL: Compute engine support for tagged queries (#128521) Begins adding support for running "tagged queries" to the compute engine. Here, it's just the `LuceneSourceOperator` because that's useful and contained. Example time! Say you are running: ``` FROM foo | STATS MAX(v) BY ROUND_TO(g, 0, 100, 1000, 100000) ``` It's *often* faster to run this as four queries: * The docs that round to `0` * The docs that round to `100` * The docs that round to `1000` * The docs that round to `100000` This creates an ESQL operator that can run these queries, one after the other and attach those tags. Aggs uses this trick and it's *way* faster when it can push down count queries, but it's still faster when it pushes doc loading things. This implementation in `LuceneSourceOperator` is quite similar to the doc loading version in _search. I don't have performance measurements yet because I haven't plugged this into the language. In _search we call this `filter-by-filter` and enable it when each group averages to more than 5000 documents and when there isn't an `_doc_count` field. It's faster in those cases not to push. I expect we'll be pretty similar.

::::{tip}
Use [`TOP`](/reference/query-languages/esql/functions-operators/aggregation-functions.md#esql-top)
if you need to keep repeated values.
ESQL: Document VALUES uniques (#128157) Documents that the VALUES aggregate function returns unique documents and points folks to the TOP aggregate function if they want to keep dupes. Closes #128091 --------- Co-authored-by: Liam Thompson <32779855+leemthompo@users.noreply.github.com>

::::{warning}
This can use a significant amount of memory and ES|QL doesn’t yet
grow aggregations beyond memory. So this aggregation will work until
it is used to collect more values than can fit into memory. Once it
collects too many values it will fail the query with
a [Circuit Breaker Error](docs-content://troubleshoot/elasticsearch/circuit-breaker-errors.md).
