> Regarding testing: we could consider adding a spanner instance to apache-beam-testing for integration testing, I'd suggest raising it on dev@ if you want to pursue it. I also just came across https://cloud.google.com/spanner/docs/emulator which could be a good option too. Its a docker container that starts up an in-memory version of spanner to test against. @TheNeuralBit Great advice as always! I tried to find something like this emulator on dockerhub but without success. I managed to successfully use this emulator, it has much better support than aws for localstack. Few comments about this PR: I am almost certain that the Schema doesn't have to be sent as proto in Read but I didn't come up with anything else. Another issue is representing the Mutation - for now it's a Row containing 4 fields: operation, table, rows and key_set. It does quite well but I wonder whether I can do it better. I erased SpannerWriteResult and return PDone for now - I don't see the way to keep it without including spanner dependencies to java.core. Because of that failure mode is FAIL_FAST and I didn't include it in configuration params. Transactions are not supported because they require a ptransform to be transferred. I suppose it's doable though and it could be a good future improvement. FYI - I'll be OOO the next week so there is absolutely no haste :) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
