RxJava Error Handling - How to add error callback

Hi @dtanabe
I am also looking for a solution to gRPC Server errors which completely disconnects daml CompletionStreams/TransactionStreams at client.

I noticed the gRPC has following retry mechanism implemented.

grpc/proposal/blob/6070a6b5cd1c014e0b5be54701ca07b8fb1c128c/A6-client-retries.md

Is daml library capable to configure the retries like mentioned here?

or is there any alternate mechanism we can use for daml java ledger apis?
