> It is useful to have an easy way to replicate data from Postgresql tables to a HBase
tables.
> I made a simple python tool which does this, called hbrep.
> hbrep is a tool for replicating data from postgresql tables to hbase tables.
> Dependancies:
>  - python 2.4
>  - hbase 0.2.0
>  - skytools 2.1.7
>  - postgresql
>  
> It has two main functions.
>  - bootstrap, which bootstraps all the data from specified columns of a table
>  - play, which processes incoming insert, update and delete events and applies them to
hbase.
> Example usage:
> install triggers:
>   ./hbrep.py hbrep.ini install schema1.table1 schema2.table2
> now that future updates are queuing, bootstrap the tables.
>   ./hbrep.py hbrep.ini bootstrap schema1.table1 schema2.table2
> start pgq ticker (this is part of skytools, it manages event queues and sends the events
to registered consumers).
>   pgqadm.py pgq.ini ticker
> play our queue consumer to replicate events
>   ./hbrep.py hbrep.ini play schema1.table1 schema2.table2
> more details in the readme.
> feedback and improvements appreciated.
