What is changed, added, or deleted? (Required)

Several docs use "node number" to mean the number of nodes, for example "Consider increasing the node number or node size for TiDB" and the heading "Change node number". "Node number" reads more naturally as a node's ID or ordinal position (node #1, node #2) than as a count. The section itself already says "You can increase or decrease the number of TiDB, TiKV, or TiFlash nodes".

The ambiguity has already caused mistranslations. The Japanese docs (i18n-ja-release-8.5) render this phrase as 「ノード番号」 ("node ID / node ordinal") instead of 「ノード数」 ("number of nodes") in two places:

  • functions-and-operators/group-by-modifier.md L47: the link text [Change node number] became 「ノード番号を変更する」 ("change the node ID").
  • tidb-cloud/releases/release-notes-2023.md L901: "You can decrease the node number via the TiDB Cloud console" became 「ノード番号をTiDB Cloudコンソール経由…で減らすこと」 ("decrease the node ID via the TiDB Cloud console").

Using "node count" or "number of nodes" in the English source removes the ambiguity for readers and for translation.

This PR replaces all 27 occurrences of "node number(s)" / "nodes number" in 10 files:

  • "node count" where the phrase is a compact noun, often parallel with "node size" or "vCPU and RAM": tidb-cloud/monitor-built-in-alerting.md (12), tidb-cloud/scalability-concepts.md (3), tidb-cloud/scale-tidb-cluster.md (5, including the heading), tidb-cloud/releases/notification-2023-11-14-scale-feature-maintenance.md, tidb-cloud/terraform-use-cluster-resource.md, tidb-cloud/tiproxy-management.md ("node counts").
  • "number of nodes" in running prose: tidb-cloud/backup-and-restore.md (2), tidb-cloud/releases/release-notes-2023.md, grafana-overview-dashboard.md ("The number of online nodes of each service").

Heading and anchor change: ## Change node number in tidb-cloud/scale-tidb-cluster.md becomes ## Change node count, so the anchor changes from #change-node-number to #change-node-count. The only two in-repo links to the old anchor (functions-and-operators/group-by-modifier.md and tidb-cloud/releases/release-notes-2023.md) are updated in this PR. After this change, no occurrences of "node number" or #change-node-number remain in the repository.

The same text exists on release-8.5 with the same occurrence counts, so the cherry-pick should apply cleanly. The Japanese docs will pick up the change through the regular translation sync.

Which TiDB version(s) do your changes apply to? (Required)

Tips for choosing the affected version(s):

By default, CHOOSE MASTER ONLY so your changes will be applied to the next TiDB major or minor releases. If your PR involves a product feature behavior change or a compatibility change, CHOOSE THE AFFECTED RELEASE BRANCH(ES) AND MASTER.

For details, see tips for choosing the affected versions.

  • master (the latest development version)
  • v9.0 (TiDB 9.0 versions)
  • v8.5 (TiDB 8.5 versions)
  • v8.1 (TiDB 8.1 versions)
  • v7.5 (TiDB 7.5 versions)
  • v7.1 (TiDB 7.1 versions)
  • v6.5 (TiDB 6.5 versions)

📝 Walkthrough

Walkthrough

Documentation updates use “node count” or “number of nodes” in scaling, restore, alert, release, and reference content. One documentation link was also updated. Thresholds, conditions, and sizing guidance remain unchanged.

Changes

Node terminology updates

Layer / File(s) Summary
Scaling and sizing guidance
tidb-cloud/scalability-concepts.md, tidb-cloud/scale-tidb-cluster.md, tidb-cloud/terraform-use-cluster-resource.md, tidb-cloud/tiproxy-management.md
Scaling descriptions and instructions use “node count.” The TiKV description continues to include storage among configurable resources.
Restore and alert instructions
tidb-cloud/backup-and-restore.md, tidb-cloud/monitor-built-in-alerting.md
Restore steps use “number of nodes.” Dedicated-plan resource usage recommendations use “node count”; alert conditions and thresholds are unchanged.
Links and descriptive text
functions-and-operators/group-by-modifier.md, grafana-overview-dashboard.md, tidb-cloud/releases/notification-2023-11-14-scale-feature-maintenance.md, tidb-cloud/releases/release-notes-2023.md
Documentation text and a link use updated node terminology. The “Services Up” description says “the number of online nodes.”

Marking as translation/no-need: the tidb-cloud/ files have no Chinese counterpart, and the two non-Cloud edits are pure English rewording that do not affect the Chinese passages (docs-cn grafana-overview-dashboard.md:19).
