For each table, we can set block size consider the data.size, this is because
that when execute query, each task will get one block to process one time,
when the blocks num < parallelism, set a reasonable block size would get
most suitable block num, to make the best of parallelism.

oduce this param

with a defined default block size.

At same time max and min block size should be restricted and validated
while creating table.

Purpose:
To configure block file size for each table on column level, so that each
table could has its own blocksize.

Add a new parameter in table properties, when create a table, the user can
set it in ddl. Add a parameter in thrift format just like other properties,
and write this in
13 matches
