rdblue opened a new pull request #2139: URL: https://github.com/apache/iceberg/pull/2139
This changes the distribution mode used by default to write the output of MERGE INTO to `none` if the table is unsorted, rather than `range`. Range distribution is expensive because it uses an extra round-robin exchange and has an extra stage to estimate skew. If the sort order of the table is not set, then it is not worth adding the extra stages for the inferred sort order. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
