A small script to export data from one Elasticsearch cluster into another.
While copying, the script will attempt to create the mapping from the source database, if it doesn't exist already.
node exporter.js -a localhost -b foreignhost // copy all indices from machine a to b
node exporter.js -i index1 -j index2 // copy entire index1 to index2 on same machine
node exporter.js -i index -t type1 -u type2 // copy type1 to type2 in same index
node exporter.js -i index1 -t type1 -j index2 -u type2 // copy type1 from index1 to type2 in index2
node exporter.js -a localhost -i index1 -b foreignhost // copy entire index1 from machine a to b
node exporter.js -a localhost -i index1 -b foreignhost -j index2 // copy index1 from machine1 to index2 on machine2
To run this script you will need at least node v0.6, as well as the nomnom and colors package installed.
