Hi Ravindra,

Only projection push down for Struct type is planned.

For complex data type, encoding is planned for the primitive types. For both
integral and dimension types, we are reusing the existing encoding types.
For Integral types, it will be reusing adaptive and adaptive delta encoding.
For dimension types, createEncoderForDimensionLegacy will be used to get the
encoder.

Thanks,
Dhatchayani
