Aerospike Ruby Client travis codecov gem

An Aerospike library for Ruby.

This library is compatible with Ruby 2.3+ and supports Linux, Mac OS X and various other BSDs.


The following is a very simple example of CRUD operations in an Aerospike database.

require 'rubygems'
require 'aerospike'

include Aerospike

client ="")

key ='test', 'test', 'key value')
bin_map = {
  'bin1' => 'value1',
  'bin2' => 2,
  'bin4' => ['value4', {'map1' => 'map val'}],
  'bin5' => {'value5' => [124, "string value"]},

client.put(key, bin_map)
record = client.get(key)
record.bins['bin1'] = 'other value'

client.put(key, record.bins)
record = client.get(key)
puts record.bins

puts client.exists(key)


More examples illustrating the use of the API are located in the examples directory.

Details about the API are available in the docs directory.

  • Mac OS X
  • other BSDs (untested)
