Bottleneck with invertedIndex:

1. As for each page first we will sort the data and generate inverted index, data loading performance will get impacted.because of this
2. Store size is more because of stroing inverted index for each dimension column which results in more IO and it impacts query performance
3. One extra lookup happenes during query due to presence of inverted index which is causing many cachline miss and it impacts the query performance
