redis-random-data-generator

In working for another NPM project I needed to populate a redis instance with a bunch of random data. I found the redis pipe command wasn't working so well so I made this script to facilitate the process.

Generator.js - quickly add random data to a redis instance.

Basic Usage:

node generator.js <type> <qty> [<key_prefix>]

• This will enter <qty> of <type> entries into the redis instance
  running at the server and port address set in the config.json
  file.

• If <key_prefix> is set then this will be prepended to the key (uuid) separated by a ":" - thanks to Alfonso Montero for this contribution

  node generator.js hash 100 session

  1)...

  100) "session:ffab3b35-09c3-4fd7-9af1-4d323534065e"

• This (config.json) file is automatically generated on running npm install redis-random-data-generator and will default to 127.0.0.1:6379 change the settings to suit your setup. If the file gets deleted the local default setting will be used.

• There is no provision yet for an array of <types> so if you
  require various entries you will need to run the command several times.

• Run npm test to perform tests on the script.

• The script uses generated uuids for keys and random lorum ipsum
  for values.

Types (others may be added in future versions i.e. geohash):

• 'string' uses SET to add a redis string value
• 'list' uses LPUSH to add a random number of values to a list
• 'set' uses SADD to add a random number of values to a set
• 'sorted' uses ZADD to add a random number of values and scores
  to a sorted set.
• 'hash' uses HMSET to add a random number of values to a hash
