Module Plasma_netfs

module Plasma_netfs: sig .. end
Accessing PlasmaFS via the Netfs.stream_fs interface
class netfs : ?repl:int -> ?verbose:bool -> ?notranslate:bool -> Plasma_client.plasma_cluster -> Netfs.stream_fs
val netfs : ?repl:int ->
       ?verbose:bool ->
       ?notranslate:bool -> Plasma_client.plasma_cluster -> Netfs.stream_fs
Access this cluster with the stream_fs interface:

  • read and write are fully implemented, and always use streaming mode. The I/O bases on the buffered access layer provided by Plasma_client, and so it is a good idea to configure some number of buffers to use, with Plasma_client.configure_buffer.
Arguments:

  • repl: The replication factor for new files. Defaults to 0, i.e. to the server default.
  • verbose: Whether to output progress messages to stderr for all metadata modifications. Defaults to false. (This exists for the command-line utility plasma.)
  • notranslate: Normally, all Plasma_error exceptions are translated to Unix_error. By setting this switch the translation is not done.


Helper for Mapred_fs.plasma_filesystem



This is an extended version of stream_fs. It exists only as a definition step for Mapred_fs.plasma_filesystem. Please don't use directly.
