Now available in preview, the In-database merge queries feature is supported for merging results of two queries that are on the same BigQuery connection. Previously, the join for merging results was always performed in Looker memory, which limited each query to 5,000 rows that could be calculated in the join. If your Looker admin has enabled the In-database merge queries Looker Labs feature, the join between two queries that are on the same BigQuery connection is performed in the BigQuery database itself. Performing the join in the database is more performant and allows for unlimited rows that can be joined.
