Description:
>From Google's Jeff Dean, in a keynote to LADIS 2009
>(http://www.scribd.com/doc/21631448/Dean-Keynote-Ladis2009, slides 66 - 67):
BigTable Coprocessors (New Since OSDI'06)
* Arbitrary code that runs run next to each tablet in table
** As tablets split and move, coprocessor code automatically splits/moves
too
* High-level call interface for clients
** Unlike RPC, calls addressed to rows or ranges of rows
* coprocessor client library resolves to actual locations
** Calls across multiple rows automatically split into multiple
parallelized RPCs
* Very flexible model for building distributed services
** Automatic scaling, load balancing, request routing for apps
Example Coprocessor Uses
* Scalable metadata management for Colossus (next gen GFS-like file system)
* Distributed language model serving for machine translation system
* Distributed query processing for full-text indexing support
* Regular expression search support for code repository
