zhengshiJ opened a new pull request, #8947: URL: https://github.com/apache/incubator-doris/pull/8947
The purpose of this function is to modify the derivation of the current statistics. There are two modifications: 1. The statistical information derivation is removed from the Node node. 2. Modify the current way of obtaining cardinality, and change it to obtain it from statistical information. For details on the modification method, see: https://shimo.im/docs/473QyOzWBjHMlZ3w The implementation of this function is divided into multiple submissions, and this submission implements the derivation of scan_node statistics. # Proposed changes Issue Number: close #xxx ## Problem Summary: The derivation of the current statistical information is coupled in the node node, and the method of calculating the cardinality is carried out by the mock method, and the ndv value is not obtained correctly. ## Checklist(Required) 1. Does it affect the original behavior: (No) 2. Has unit tests been added: (No) 4. Has document been added or modified: (No Need) 5. Does it need to update dependencies: (No) 6. Are there any changes that cannot be rolled back: (No) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
