This > implies that 1) BigQueryIO puts unnecessary overheads on BigQuery API layer > by sending requests too fast 2) log file becomes very big because of repeated > same error messages. Currently we use 50 shards for writing data into > BigQuery and in each bundle 20-30 futures are executed simultaneously with > unlimited thread pool. It would be worth investigating whether just single > thread pool is sufficient for running concurrent insertAll. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
