[This test on roachdash](https://roachdash.crdb.dev/?filter=status:open%20t:.*TestSplitAtTableBoundary.*&sort=title+created&display=lastcommented+project) | [Improve this report!](https://github.com/cockroachdb/cockroach/tree/master/pkg/cmd/bazci/githubpost/issues)

Start with sql/tests.TestSplitAtTableBoundary and inspect the linked failure report, including outputs.zip/logTestSplitAtTable3919781077. Compare this failure with the repeated failures listed for other branches and determine the underlying cause. Done means the test passes reliably, including under race=true, and the failure no longer recurs.
