gearman client and worker library

Gearman Client and Worker

  • full implementation of worker and client
  • lean abstraction over raw gearman protocol
  • lots of unit tests
  • fast
  • small
  • fully interoperable with gearman clients and workers written in other languages
  • lacks elegant high level abstractions for doing work. A bit more boilerplate to write
  • only supports 1 server connection per client/worker
