>
> for each table, we store file logic length in pg_aoseg metadata table.
> when scanning tables, we obtain blocks information from HDFS(or cache)
> we need to ensure the file length in HDFS equals to the logic length of file
> in pg_aoseg.
> Again, we also need to ensure after we assign each blocks to virtual
> segments, the total length of splits equals to the logic length of file in
> pg_aoseg.
