Optimizes the table data, depending upon table size.
Apache CarbonData pushes as much of query processing as possible close to the data to minimize the amount of data being read, processed, converted and transmitted/shuffled. Using projections and filters it reads only the required columns from the store and also reads only the rows that match the filter conditions provided in the query.
*Bucketing: It is a technique that is used for uniform distribution of data across files in CarbonData. It enhances the performance of join queries. While loading the data, records are placed into buckets based on the hashing algorithm(s). During the execution of join queries the records can be fetched from buckets without the need of shuffling. This feature is used to distribute/organize the table/partition data into multiple files placing similar records in the same file.
