             Summary: Add support to reading loading files of multiple prefixes
                 Key: ASTERIXDB-3079
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-3079
             Project: Apache AsterixDB
          Issue Type: Improvement
          Components: EXT - External data
    Affects Versions: 0.9.8
            Reporter: Hussain Towaileb
            Assignee: Hussain Towaileb
             Fix For: 0.9.9


Currently, we provide a single prefix and load the files metadata under that prefix. With the support for computed fields for operators like IN operator, we can end up with multiple prefixes.

 

Example, given the following prefix user-data/\{userid:int}

 

 
|SELECT *|
|FROM userdata|
|WHERE user_id IN [1, 2]|

 

 

The above translates to loading the data for the prefixes:

 

 
|user-data/1|
|user-data/2|
