Cache server
class type cache_config = object .. end
Configuration data for a server
type
A cache server instance
val create : cache_config -> cache_instance
Creates a cache instance for the passed cache_config
val bind : Rpc_server.t -> cache_instance -> unit
Binds the cache procedures in the passed RPC server. One can bind the
cache to several servers, or even to no servers if only local accesses
happen.
val activate : Unixqueue.event_system -> cache_instance -> unit
Activates the cache: Loads contents from files, and establishes
timers. Must be called after bind.
val save : cache_instance -> unit
Saves the complete instance immediately to disk
val verify : log:(string -> unit) -> cache_instance -> unit
Runs a routine that checks the structure of the cache instance.
Messages are printed to log.
type
}
The key and the modulo (number of servers)
val set_directly : cache_instance ->
full_key ->
string ->
Cache_client.timestamp ->
Cache_client.set_options -> [ `Not_stored | `Stored ]
Modifies the cache directly
val get_directly : cache_instance ->
full_key ->
Cache_client.get_options -> [ `Found of Cache_client.entry | `Not_found ]
Reads from the cache directly
val delete_directly : cache_instance ->
full_key ->
Cache_client.timestamp -> Cache_client.delete_options -> unit
Deletes directly in the cache
val clear_directly : cache_instance -> unit
Clears the whole cache directly
val get_config : cache_instance -> Cache_client.config
Get the cache's config
val set_config : cache_instance -> Cache_client.config -> unit
Set the cache's config
val get_stats : cache_instance -> Cache_client.stats
Get the statistics
val clear_counters : cache_instance -> unit
Reset the statistics
val shutdown : cache_instance -> unit
Shuts the instance down.
This deletes any timers, and stops any save operations currently
being performed. It does not stop the RPC servers, however, because
the cache instance does not remember them, i.e. it is the task of
the user of this module to stop the RPC servers to which the
instance has been bound.
