wangyum opened a new pull request, #37069: URL: https://github.com/apache/spark/pull/37069
### What changes were proposed in this pull request? This PR adds `ANALYZE TABLE tbl COMPUTE STATISTICS;` as a workaround when there is not enough memory to build and broadcast the table. ### Why are the changes needed? The current workaround has the following disadvantages: 1. Setting `spark.sql.autoBroadcastJoinThreshold` to -1 will disable all broadcast joins. 2. We don't know the specific value of `spark.driver.memory` should be set. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Manual testing: ``` Not enough memory to build and broadcast the table to all worker nodes. As a workaround, you can either disable broadcast by setting spark.sql.autoBroadcastJoinThreshold to -1 or increase the spark driver memory by setting spark.driver.memory to a higher value or analyze these tables through: ANALYZE TABLE `tpds5t`.`item` COMPUTE STATISTICS;." ``` -- This is an automated message from the Apache Git Service.
