dxf: use correct store in add-index, checksum by copr in import-into, and enable DXF service by D3Hunter · Pull Request #62224 · pingcap/tidb

D3Hunter · 2025-07-04T09:58:13Z

What problem does this PR solve?

Issue Number: ref #61702

Problem Summary:

What changed and how does it work?

use correct store to get tableInfo and check table emptyness in add-index
for import into: pass Store related to the task ks, and use TiKVChecksumManager to do checksum for nextgen, and use task ks store to rebase auto ids.
add DXFSvcTaskMgr which is initialized in user keyspace to access DXF, previous TaskManager always point to current instance
refine log to print task-key
skip running DXF on user keyspace
for cross ks session, use a noop validator to avoid "Information schema is changed during the execution" error, as cross ks info schema is not synced right now.

Hi @D3Hunter. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.
