kishoreg opened a new pull request #3727: Matches support in pql
URL: https://github.com/apache/incubator-pinot/pull/3727
 
 
   The first step towards supporting search analytics functionality in Pinot. 
   syntax
    <colName> MATCHES ($queryString, $queryMatches)
   
   Sample query
   if col is a map 
   - Select count(*) from T where col MATCHES ('k1=v1');
   
   if col is a text 
   - Select count(*) from T where col MATCHES ('fox AND brown', '{queryFormat:lucene}');
   
   if col is a nested json
   - Select count(*) from T where col MATCHES ('foo.bar=v1', '');
   
   The second argument 'query options' is a json string and allows us to add more options later on. 
   
   Looking for feedback on the syntax. 
   
   For e.g. MySQL has the following syntax
   `MATCH (col1,col2,...) AGAINST (expr [search_modifier])`
   
   Amazon Athena
   `WHERE json_array_contains(json_extract(users, '$.projects'), 'project2')`
