## Versions - [x] dev - [ ] 4.x - [ ] 3.x - [ ] 2.1 or older (not covered by version/language sync gate) ## Languages - [x] Chinese - [x] English ## Docs Checklist - [x] Checked by AI - [x] Test Cases Built - [x] Updated required version and language counterparts, or explained why not - [x] If only one language changed, confirmed whether source/translation counterparts need sync ## Summary Related implementation: https://github.com/apache/doris/pull/68791 Document `external_scan_consistent_hash_spread_num` in the existing English and Chinese session-variable reference: - Default `1` preserves original scheduling; it does not mean a single backend. - Explicit `0` enables automatic spreading across eligible compute-group backends. - Values above `1` bound hash candidates when file caching or consistent hashing is enabled. - Explain query-local weights, random ties, single assignment, locality, global redistribution, cache costs, and persisted global values. Only the current development documentation is updated because this feature is proposed for master and has not been released or backported. Existing page paths, front matter, sidebar entries and released-version documentation are unchanged. ## Validation - The repository's `scripts/check_md_links_single.py --no-external` passes for both changed pages. - Front matter, heading hierarchy, fenced SQL blocks, existing sidebar placement and English/Chinese semantic consistency were checked. - Implementation validation: 33 focused FE unit tests, standard FE build/Checkstyle, and the session-variable and external-scan regression suites passed. These cover the default, opt-in modes, bounds and reset behavior. - A full Docusaurus site build was not run locally; the repository build workflow remains required. -- This is an automated message from the Apache Git Service.
