[2/2] carbondata git commit: [CARBONDATA-3015] Support Lazy load in carbon vector

Posted by ku...@apache.org.
[CARBONDATA-3015] Support Lazy load in carbon vector

Even though we prune the pages as per min/max there is a high chance of false positives in case of filters on high cardinality columns.
So to avoid that we can use the lazy loading design. It does not read/decompresses data and fill the vector immediately
when the call comes for data filling from spark/presto.
First only reads the required filter columns give back to execution engine, execution engine starts filtering on the filtered column vector
and if it finds some data need to be read from projection columns then only it starts reads the projection columns and fills the vector on demand.
It is the concept of presto and same is integrated with spark 2.3. Older versions of spark cannot use this advantage as ColumnVector interfaces are non-extendable.
For the above purpose added new classes 'LazyBlockletLoad' and 'LazyPageLoad' and changed the carbon vector interfaces.

This closes #2823
