Ignoring all the other advantages messaging has, they’ll ask us the following question: “But isn’t RPC faster than messaging?” In place of RPC, 1 they may substitute a different term or technology like REST, microservices, gRPC, WCF, Java RMI, etc. So we’ll just use “RPC” for short. But the answer isn’t that simple.

Seer uses a lightweight RPC-level tracing system to collect request traces and aggregate them in a Cassandra database. Most of the time Seer is just using its high-level RPC tracing which adds low overhead (less than 0.1% At the core of Seer is a DNN making predictions based on the RPC-level traces that are gathered.

That’s why I wrote Comlink , which is a library that uses an RPC protocol under the hood to make it seem like the objects from a worker are accessible from the main thread and vice versa. Comlink is not magic, it still has to use postMessage for the RPC protocol. When using Comlink, you don’t have to deal with postMessage at all.

That’s where Remote Procedure Calls — RPC — comes in. A lot of messaging protocols have been developed in the past to address this. SOAP was bulky, and REST is a trimmed-down version but we need an even more efficient framework.

Getting the timings of the statement completed and RPC completed events from Extended Events along with the database_transaction_end event timing shows the round-trip delay from the app tier closing out the transaction on the open connection. The problem is ultimately the result of the delay in processing the application side commit point.

As we’ve seen a number of times before, there’s a trade-off between fast one-sided access that doesn’t involve the remote CPU, and a more traditional RPC style that does. In particular, if you end up needing to make multiple one-sided requests to get to the data you really need, it’s often faster to just go the RPC route.

What if we want to update more than one field and do it atomically in a single RPC? Building on top of this we could just implement an update method for every field: one for Production format, another for title and so on: [link] This can become unmanageable when maintaining our APIs due to the number of fields on the Production.

It turned out that an RPC call to a legacy service, whose response value was stored in the 72nd column in the database table, wasn't even necessary. After we had instrumented the legacy code with events, we had a subscriber module that received all these events. We were able to identify the part that took too long.
