Summary: new feature for griffin COMPLETENESS dq type
Key: GRIFFIN-289
URL: https://issues.apache.org/jira/browse/GRIFFIN-289
Project: Griffin
Issue Type: New Feature
Components: completeness-batch
Affects Versions: 0.3.1-incubating
Reporter: Zhao Li
Hello
Now we use griffin measure module to check batch data quality. In COMPLETENESS
dq type, griffin checks how many incomplete records in table, and griffin only
check if one column is 'null' or not.
However, only "null" is not enough to consider whether one column is invalid or
not. In our condition, analysts may consider other value is invalid even though
they are not "null". For example, one column named "company", if company in
("a", "b", "c"), this record is invalid.
Here we need two ways for user to filter incomplete record, one is
"enumeration", users write all invalid values they think for one column; the
other is "regular expression", users write regular expression to match invalid
values for one column.
Could griffin updates COMPLETENESS dq type to support our "enumeration" and
"regular expression" way to filter incomplete records?
Regards
Zhao
