What changed

  • Send rocksdb_block_read as the order_by value when Read IOPS is selected.
  • Add Cypress coverage that asserts the backend-compatible query parameter.

Why

The TopSQL summary API rejects block_read; the accepted ordering value is rocksdb_block_read. The response payload continues to use rocksdb_block_read_count.

Issue Number: ref tikv/tikv#19867

Related PR: #1917

Validation

  • pnpm exec prettier --check packages/tidb-dashboard-lib/src/apps/TopSQL/pages/List/List.tsx packages/tidb-dashboard-for-op/cypress/integration/topsql/topsql.spec.ts
  • pnpm exec eslint packages/tidb-dashboard-for-op/cypress/integration/topsql/topsql.spec.ts
  • corepack pnpm --filter @pingcap/tidb-dashboard-lib build
  • Manual staging API check: order_by=block_read is rejected, while order_by=rocksdb_block_read passes parameter validation.

The existing downstream column_type schema scan failure is independent of this frontend parameter fix.

Summary by CodeRabbit

  • Bug Fixes
    • Fixed Top SQL Read IOPS sorting to use the correct backend-compatible ordering value.
    • Preserved compatibility with legacy Top SQL links by automatically converting the previous Read IOPS URL parameter to the supported format.
    • Added coverage to verify that Read IOPS sorting displays correctly and sends the expected request parameter.

📝 Walkthrough

Walkthrough

TopSQL now sends rocksdb_block_read for RocksDB block read ordering. URL state normalization preserves legacy block_read values. Cypress tests verify request URLs, page URLs, and the Read IOPS selector.

Changes

TopSQL order-by compatibility

Update order-by value and validate URL state
ui/packages/tidb-dashboard-lib/src/apps/TopSQL/pages/List/List.tsx, ui/packages/tidb-dashboard-for-op/cypress/integration/topsql/topsql.spec.ts
The order-by enum now uses rocksdb_block_read. URL normalization converts legacy block_read values. Cypress tests verify current and legacy URL behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 9d864

The PR changes Read IOPS requests to use rocksdb_block_read, but the end-to-end assertions do not ensure the rejected block_read parameter is absent. The change is mergeable with owner awareness or follow-up to tighten the request and URL checks.

Poem

A rabbit checked the order with care
RocksDB values now travel fair
Cypress watched the request go by
The page kept legacy links in line
And Read IOPS stayed clear and bright

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert that the legacy parameter is removed.

These assertions only check that rocksdb_block_read is present. They also pass if order_by=block_read remains as a duplicate parameter. Add negative assertions for the request URL and page URL.

Proposed test fix
         cy.wait('`@getTopsqlSummary`')
           .its('request.url')
           .should('include', 'order_by=rocksdb_block_read')

In response to a cherrypick label: new pull request created to branch release-8.5: #1928.
But this PR has conflicts, please resolve them!

jiong-nba added a commit to ti-chi-bot/tidb-dashboard that referenced this pull request Sep 8, 2026
The release-8.5 branch already contains the Read IOPS ordering fix and its Cypress coverage from pingcap#1925 (158bc4d). Remove the conflict markers and master-only URL filtering code introduced by the automated cherry-pick of pingcap#1923. The resolved tree matches release-8.5; no additional feature backport is needed.
