We need to maintain backwards compatibility.</p> <p>The incompatibility is a result of a transactionId field added to the CanCommitTransaction, CommitTransaction, AbortTransaction protobuf messages.</p> <p>Solution:</p> <ul class="alternate" type="square"> <li>In CanCommitTransaction, CommitTransaction, AbortTransaction protobuf messages make the transactionId field optional.</li> </ul> <ul class="alternate" type="square"> <li>Add an optional version # field to the CreateTransaction protobuf message. A base Helium node wouldn't set the version so it will be 0.</li> </ul> <ul class="alternate" type="square"> <li>Pass the CreateTransaction version # to the ShardTransaction.</li> </ul> <ul class="alternate" type="square"> <li>On ReadyTransaction message, the ShardTransaction sends the version # with the ForwardedReadyTransaction message to the Shard.</li> </ul> <ul class="alternate" type="square"> <li>In the Shard, on ForwardedReadyTransaction, if the version # &lt; 1 (Helium-1 version), create a BackardsCompatibleThreePhaseCohort actor with the transactionId and pass its actor ref back in the response. Otherwise pass the Shard actor ref back as it currently does.</li> </ul> <ul class="alternate" type="square"> <li>In BackardsCompatibleThreePhaseCommitCohort, on CanCommitTransaction, CommitTransaction, AbortTransaction messages, since the transactionId will be null or empty, create a new message with the cached transactionId and forward it to the Shard. Everything should work as is from there.</li> </ul> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-980
