// Set the key in the begin transaction request to the txn's anchor key.so my assumption would be that the merge txn writing its txn record lazily somehow causes this problem. @nvanbenschoten, could you take a look? |

I've tracked this down to a flake in the test and not an incompatibility between merges and omitted BeginTxns. The test installs a |

@tbg I'm running out of time to hack on this. I understand the problem well enough now to not be worried. It's a bug in the test, not in the code, so I think I'd feel comfortable skipping the test until I can resolve it. What do you think? |

SGTM, I can also take a look but since the weekend is coming up let's skip
it.

Informs cockroachdb#33656. I'm not aware of any places where this is necessary for correctness, but it is useful to prevent test flakes until tests are updated to expect lazy transaction record creation. Release note: None

Closes cockroachdb#33656. This fixes the root problem instead of sending BeginTxn requests to appease the test. This is an important change to make now because if we left merges using BeginTxn requests in 19.1 then we wouldn't be able to remove BeginTxn support in 19.2. Release note: None

34934: storage: stop sending BeginTxn requests in merge transactions, remove EagerRecord r=nvanbenschoten a=nvanbenschoten Closes #33656. This fixes the root problem instead of sending BeginTxn requests to appease the test. This is an important change to make now because if we left merges using BeginTxn requests in 19.1 then we wouldn't be able to remove BeginTxn support in 19.2. The PR then removes the EagerRecord transaction option entirely. 35019: stats: temporarily disable automatic stats r=rytaft a=rytaft This commit temporarily disables automatic statistics. We will reenable automtic stats once it's confirmed that #34928 fixes the performance issues.
