# pg_nice_cluster

this is a little tool to help you use the CLUSTER command of postgres while maintaining the ability to read from the table.

## installation

in your Gemfile add

    gem 'pg_nice_cluster', :git => 'git://github.com/adeven/pg_nice_cluster.git'

    

then

    bundle install

## usage

    pg_nice_cluster --help

    Options:

         --db,      -d :   database name

         --user,    -u :   user name (default: postgres)

         --pass,    -p :   password

         --host,    -h :   host name (default: localhost)

         --prefix,  -r :   prefix for the temporary tables and indexes (default 'cluster_') (default: cluster)

         --minsize, -m :   cut off size for small tables in mb (default: 100)

         --table,   -t :   table name if only one table should be clustered

## requirements

* tables will be EXCLUSIVE locked for the operation

* enough disk space for the biggest table times two

* enough ram for the indexes of the table with the largest combined indexes

* depending on your table size, quite some time
