[jira] [Commented] (BEAM-12472) BigQuery streaming writes can be batched beyond request limit with BatchAndInsertElements

["Tudor Plugaru (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-12472?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17383918#comment-17383918 ] 

Tudor Plugaru commented on BEAM-12472:
--------------------------------------

This is an issue on the Python SDK also and also using `ignore_insert_ids=True`. The sink creates batches bigger than BigQuery 10MB limit.

I fixed this by setting `batch_size=1` for tables that have issues.

> BatchAndInsertElements accumulates all the input elements and flushes them in finishBundle.
> However if there is enough data the request limit for bigquery can be exceeded causing an exception like the following.  It seems that finishBundle should limit the # of rows and bytes and possibly flush multiple times for a destination.
> Work around would be to use autosharding which uses state that has batching limits or to increase the # of streaming keys to decrease the likelihood of hitting this.
