> The index maintenance for transactions follows the same model as non 
> transactional tables - coprocessor based on data table updates that looks up 
> previous row value to perform maintenance. This is necessary for non 
> transactional tables to ensure the rows are locked so that a consistent view 
> may be obtained. However, for transactional tables, the time stamp oracle 
> ensures uniqueness of time stamps (via transaction IDs) and the filtering 
> handles a scan seeing the "true" last committed value for a row. Thus, 
> there's no hard dependency to perform this on the server side.
> Moving the index maintenance to the client side would prevent any RS->RS RPC 
> calls (which have proved to be troublesome for HBase). It would require 
> returning more data to the client (i.e. the prior row value), but this seems 
> like a reasonable tradeoff.
