When I said "checking TV", I meant using the nodeApiVersions to check the TV on requests -- this will be in ApiVersionsResponseData.finalizedFeatures. We will also want to check ApiVersionsResponseData.finalizedFeaturesEpoch when we update the feature version. I was thinking the transaction manager could have some sort of central mechanism that checks the api version and updates on the various requests. This could be done in a helper. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
