We should suppot limit zonemap index. In the current scenario of doris, excessively long zonemap indexes do not contribute significantly to query improvement, but rather consume a lot of additional memory and storage resources. So it is wise to limit the length of zonemap for large types of objects and long strings For example, postgresql's Brin index, by default, records 128 rows of data once. The current Doris default page size is 64k, so a reasonable zonemap index length should be about 512byte. -- This is an automated message from the Apache Git Service.
