BigQuery Storage Write API v1: Request 'AppendRows' from role 'cloud-dataengine-globalrouting' throttled: Task is overloaded (memory-protection) go/tr-t

[etrandafir93]

Environment details

Java 21
Spring Boot 3.3.3
google-cloud-bigquery: 2.42.1
google-cloud-bigquerystorage: 3.9.0

Steps to reproduce

1. Listen to a Kafka topic
2. For each message, send one or more records (within a JSONArray) to BigQuery, using a JsonStreamWriter
3. If sending to BQ fails, retry up to 9 times with a delay of one second

Code example

The code is pretty straight-forward, nothing special here:

private final JsonStreamWriter streamWriter;

// retried up to 9 times with a 1s delay
public AppendRowsResponse write(JSONArray json) {
      var resp = streamWriter.append(json).get();
     // ...
}

Any additional information below

I've noticed similar issues being reported for the nodejs and dotnet clients.

I know this involves both BQ and BQ Storage, but I transferred it to the BQ storage repo because I think it skews slightly storagey-er, and I'm assigning to my java colleagues to address. Thanks for linking to the node and dotnet clients!

hello, I have managed to sort out the issue. This application was writing to different BigQuery tables and it seems that a different module (writing to a different table) was using too many connections, causing this throttling issue.

After starting to use multiplexing - and using a shared connection pool - the issue was solved.
