Hi, I am a newbie to Calcite and SQL. Recently, I am trying to develop a calcite adapter for a new kind of data source. This data source has some different operators compared to SQL. For example, in SQL, if we want to find all rows that don't contain a certain keyword:
select * from table where value not like 'abc%' In this new data source, the query string is: select * from table where value <> 'abc%' So in this data source, <> is a new operator. As of now, I have to manually generate the where clause in the filter rule. Does Calcite support adding new operator, so that it can automatically translate? Thanks! Sincerely, Junwei Li
