[GitHub] [doris] dataroaring opened a new pull request, #11372: [bug](storage-scanner) fix infinite loop when reading wide table
dataroaring opened a new pull request, #11372:
URL: https://github.com/apache/doris/pull/11372
When a wide table is read, the 1st batch would be exceed raw_bytes_threshold,
so Scanner should read at least 1 row.
Actually, we should adjust batch size automatically to reduce memoery usage.
