Batch operations applied atomically.

Sourceval make : unit -> writebatch

Initialize a batch operation.

Sourceval put : writebatch -> string -> string -> unit

put writebatch key value adds or replaces a binding.

Source

val put_substring : 
  writebatch ->
  string ->
  int ->
  int ->
  string ->
  int ->
  int ->
  unit

put_substring writebatch key off1 len1 value off2 len2 adds or * replaces a binding for the substrings of key and value delimited by * the given offsets and lengths. *

raises Error
if the offset, length pairs do not represent valid * substrings

Sourceval delete : writebatch -> string -> unit

delete writebatch key removes the binding for key, if present..

Sourceval delete_substring : writebatch -> string -> int -> int -> unit

delete writebatch s off len removes (if present) the binding for the * substring of s delimited by the offset off and the length len.

Sourceval write : db -> ?sync:bool -> writebatch -> unit

Apply the batch operation atomically. *

parameter sync
whether to write synchronously (default: false)
