[jira] [Created] (IMPALA-9662) Add builtin functions for masking
UTF-8 strings
Quanlong Huang created IMPALA-9662:
--------------------------------------
Summary: Add builtin functions for masking UTF-8 strings
Key: IMPALA-9662
URL: https://issues.apache.org/jira/browse/IMPALA-9662
Project: IMPALA
Issue Type: New Feature
Reporter: Quanlong Huang
The existing mask functions can only deal with ASCII characters. It will be very useful to provide mask functions that can deal with UTF-8 characters.
Some common scenarios:
* Masking the last two UTF-8 characters of Chinese names.
* Show only the first several UTF-8 characters of Chinese addresses and mask all the remaining characters.
However, this depends on our BE support for UTF-8 strings.
