4S-BACKEND_SETUP(1J) 4store 4S-BACKEND_SETUP(1J)
NAME
4s-backend-setup -- Create a new 4store KB
SYNOPSIS
4s-backend-setup kbname [--node node-number] [--cluster cluster-size] [--segments segment-count] kb-name
--node Number of this node in the cluster, values range from 0 to cluster-size - 1. The default is 0.
--cluster
The number of nodes in the cluster. The default is 1.
--segments
The number of segments in the cluster. The default is 2. We recommend one for each CPU core in the cluster as a good

EXAMPLES
$ 4s-backend-setup --node 0 --cluster 1 --segments 4 demo
Creates the indexes for a single-machine KB with four segments, named "demo".
