> * Repartition WriteStatus before index writes, in a way that each WriteStatus with new records are not clubbed together.
>  * This repartition will improve parallelism for this hbase index operation.
>  * In HBaseIndex puts call, there is a sleep of 100 millis for each batch of puts. This implementation assumes negligible time for puts, but for large batches of puts it is inefficient.
>  * Using rate limiter will be efficient compared to sleep as it accounts for the time taken for puts as well.
