new( storage_host_uri:, namespace: )

See Hoodoo::TransientStore::Base.new for details.

Do not instantiate this class directly. Use Hoodoo::TransientStore.new.

The redis-rb gem is used to talk to Redis and requires connection UIRs with a redis protocol, such as redis://localhost:6379.

TCP keep-alive is enabled for the server connection.

def get( key: )
  result = @client.get( namespaced_key( key ) )
  return result.nil? ? nil : ( JSON.parse( result ) rescue nil )
end
set( key:, payload:, maximum_lifespan: )

See Hoodoo::TransientStore::Base#set for details.

The payload is encoded into JSON for storage and automatically decoded by get; so callers don't need to do marshalling to Strings themselves.

def set( key:, payload:, maximum_lifespan: )
  nk = namespaced_key( key )

  @client.set( nk, JSON.fast_generate( payload ) )
  @client.expire( nk, maximum_lifespan )

  true
