Motivation
At present, the underlying storage in Doris is column storage. But query
execution needs to be transferred to the query layer for execution by
row-to-column first. Such an implementation maybe cause the performance problem。

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

Hi,
Hi Thomas Cai,
I did the work to push down the limit clause for odbc table and mysql table.
You can refer to this
pr：https://github.com/apache/incubator-doris/pull/4707/files.
If you want better performance of mapping table with limit clause, please
update doris version after 0.13.15.

Motivation
At present, Doris support 3 type join: shuffle join, broadcast join, colocate
join.
Except colocate join，another join will lead to a lot of network consumption.
For example, there a SQL A join B, the cost of network.
* broadcast join: if table A is divided into three parts，the n

Wonderful proposal!

Motivation
At present, many customers need to access the external table through Doris, but
Doris only supports accessing the external table of MySQL at present. This
problem makes it difficult for users of other databases to use Doris.
