ddl: support set explicit task type for ddl request #45789

glorv · 2023-08-03T09:43:11Z

What problem does this PR solve?

Issue Number: ref #44517

Problem Summary:

What is changed and how it works?

Set the ExplicitRequestSourceType for all ddl kv request and ingest request to support control ddl tasks as background tasks.
This PR depends on tikv/client-go#890, that is, only set the ExplicitRequestSourceType to ddl if RequestSourceType is not ddl. In both ways, tikv can parse the source component as ddl correctly.

NOTE: Background control for DDL distributed framework is not fully supported currently because the framework itself is not mature. We will see what need to do after the the framework supports handling ddl jobs.

Hi @glorv. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

ddl/column.go

@@ -1443,7 +1444,7 @@ func (w *updateColumnWorker) cleanRowMap() {
 // BackfillData will backfill the table record in a transaction. A lock corresponds to a rowKey if the value of rowKey is changed.

Why it cannot use WithInternalSourceType? it should also be ddl?

The ddlJobSourceType() returns something like "ddl_add_index", so in our current check logic, this can't be recognized as ddl.
