[grpc-io] Re: gRPC & transaction support

Dead issue but I would like to resurrect it because this wasn't answered at all. Simple use case which can easily illustrate the problem: Two different services OrderService (with CreateOrder method) and AuditService (with Audit method). You want to create the order and, in case everything

Re: [grpc-io] Re: gRPC & transaction support

You need a database and logger service that supports XA transactions. Sometimes it is easier to just log in the database under the same transaction. > On Nov 5, 2018, at 3:16 AM, glertxu...@gmail.com wrote: > > Dead issue but I would like to resurrect it because this wasn't answered at >

Re: [grpc-io] Re: gRPC & transaction support

Regardless of what google does or doesn’t do, you can’t solve the problem without XA transactions - either built in or rolling your own (lots of work and not very performant). The easiest way is to log everything in a persistent log that will occur, do the operations and verify that the

Re: [grpc-io] Re: gRPC & transaction support

The problem you are describing is pretty common and not specific to gRPC, it will be there for any micro service based architecture. Typically it will be the orchestration layer that will be responsible for making sure that both operations succeed, and implement any retry logic. Or have the order

Re: [grpc-io] Re: gRPC & transaction support

The user group for an RPC framework is not the right place to ask how you should implement your transactions. This is 100% orthogonal issue, and one that you would have with REST services too. On Mon, Nov 5, 2018 at 6:13 PM wrote: > I find really hard to believe that Google uses XA

[grpc-io] Re: gRPC & transaction support

I think OP hit the nail on the head with REST being a bad fit for transactions. A previous team I worked on had pretty much the same problem. There are two solutions to having transaction like semantics. 1. Make all RPCs compareAndSwap-like, effectively making them atomic operations.

I find really hard to believe that Google uses XA transactions for its own services. Take this AuditLog service as an example which presumably is used/consumed as a middleware on their services (due to

Just to finish up the discussion, at least from my side, I will answer one by one: @Christian Rivasseau I agree that this is not the correct forum but as I wasn't the one that opened the issue I found it really handy to re-ask in a forum where lots of expert people could expose their own

Re: [grpc-io] Re: gRPC & transaction support

Not sure if it is the OP, but given the order service example cited, a fairly simple solution that isn’t transactional, would be: use service that hands-out globally unique txIDs. 1) use audit service to log “handling order for txID” 2) use order service to commit order, attaching TxID to the
