Hi, I am trying use calcite and develop a custom adapter. I have implemented the SPI and able to get basic enumerator to work with a simple select query and no where clause.
Trying to understand how to convert operators to range scan and push them to the underlying data source. Should it be a rule or a visitor if yes how do you subset the nodes so that only the range scannable entity is delivered to the converter. A link to a working example would help. The data source has range scan capability and I can make a method call to it. Thanks and regards, Ambud
