--------------------------------------
Summary: Document about memory management for writing UDAFs
Key: IMPALA-9570
URL: https://issues.apache.org/jira/browse/IMPALA-9570
Project: IMPALA
Issue Type: Documentation
Reporter: Quanlong Huang
Assignee: Kris Hahn
Attachments: apache doc.png, cloudera doc.png
In the current document, we have few words about memory management for writing
UDAFs: [https://impala.apache.org/docs/build/html/topics/impala_udf.html]
The only related sentense is "A serialize function that ... frees any memory
allocated during the init, update, and merge phases."
We can add more for clarifying it or add this link for further reading:
[https://github.com/apache/impala/blob/2f53783b14ddf215a4c96bc52a511d3a83896128/be/src/udf/udf.h#L358-L365]
