Hello,
I have just recently set up in Python a streaming pipeline to BigQuery using the Storage Write API and so far it seems to be working fine. My doubt comes with the following advise found in AppendRows documentation:
As a best practice, send a batch of rows in each AppendRows call. Do not send one row at a time.
As an initial development, I am currently sending one row at a time (contrary to what's advised), however, I would like to know exactly the advantages batching presents here for my streaming application in order to maybe adapt moving forward to this approach.
Thanks!
Batching rows when using the Storage Write API in BigQuery provides several key advantages:
To optimize your use of the Storage Write API, consider grouping rows into batches that are as large as feasible given your latency requirements and the memory capacity of your environment. Testing different batch sizes might also help you find the optimal configuration for your specific use case, balancing between throughput, latency, and resource utilization.
