Module Mapred_sorters

module Mapred_sorters: sig .. end
Sorter classes

val null_sorter : Mapred_def.mapred_env ->
Mapred_def.mapred_job_config -> float -> Mapred_def.sorter
This "sorter" just copies the input unmodified to the output
val generic_sorter : hash:(string -> int -> int -> int) ->
cmp:(string -> int -> int -> string -> int -> int -> int) ->
Mapred_def.mapred_env ->
Mapred_def.mapred_job_config -> float -> Mapred_def.sorter
The sorter orders the records first by the hash of the key. If two hashes are equal, the keys are directly compared.

The functions hash, and cmp are defined as for Mapred_def.sorter.
