Insert Into

When performing data insert, each insert in SQL takes up 50 to 100ms. Is there any way to increase efficiency?

It is not recommended to insert data piece by piece to OLAP. It is usually inserted in batches. Both methods take up the same amount of time.

This can be solved by changing the timeout limit for stream load RPC. Also, change the following two items in fe.conf and be.conf to larger values (you can also make the adjustment in the Manager page):

By default, the query timeout duration is 300s. You can set the query_timeout parameter to extend this duration. The unit is second.
