spanner-client: Retry PDML on "Received unexpected EOS on DATA frame from server" #120
Description
This bug is related to the Spanner client library.
For long lived transactions (>= 30 minutes), in the case of large PDML changes, it is possible that the gRPC connection is terminated with an error "Received unexpected EOS on DATA frame from server".
In this case, we need to retry the transaction either with the received resume token obtained on reading the stream or from scratch. This will ensure that the PDML transaction continues to execute until it is successful or a hard timeout is reached.
We have already implemented such change in the Java client library, for more information see this PR: googleapis/java-spanner#360.
In order to test the fix, we can use a large spanner database. Please speak to @thiagotnunes for more details.
