anchor.diff:  * **operator** - Filter operator: `eq`, `ne`
   * **values[]** - One or more filter values
   
  +There are some limitations:
  +* Filtering is enabled only on indexed tables
  +* Index on a filtered column of the source table cannot be removed

   #### Alias table columns
   By default, the alias columns are automatically synced with the source table. You can disable this behaviour
   by setting up `aliasColumnsAutosync` to `false` and setting up list of columns by `aliasColumns` parameter.
  
positive.code:                     "name_id",
                      "nm_id"
                  ],
                  "bucket": {
                      "uri": "https://connection.keboola.com/v2/storage/buckets/in.c-main",
                      "id": "in.c-main",
  
negative.code: - `whereColumn=UserId&whereValues[]=23423&whereValues[]=123` - Filters by multiple values of one column.
  - `whereColumn=UserId&whereValues[]=23423&whereOperator=ne` - Uses a different comparison operator.
  
  Only [Indexed columns](#reference/tables/create-column-index/mark-column-as-indexed) can be used in the `whereColumn` parameter.
  The comparison operator essentially behaves like the [SQL IN](http://www.w3schools.com/sql/sql_in.asp) (and NOT IN) operator. That is, the 
  `eq` value matches if any `whereValues` match, and the `new` value matches if none `whereValues` match.
