- class k2hdkc.k2hdkc.K2hdkc(conf_file, port=8031, cuk=None, rejoin=True, rejoin_forever=True, clear_backup=True)
Bases:
object
K2hdkc class provides methods to handle key/value pairs in k2hdkc hash database.
- K2H_INVALID_HANDLE = 0
- add_subkey(key, subkey, subval, check_attr=True, password=None, expire_duration=None, time_unit=TimeUnit.SECONDS)
Adds a new subkey to a current subkey.
- cas_decrement(key, password=None, expire_duration=None)
Decrements a variable in a cluster by using a CAS operation.
- cas_get(key, data_type, password=None, expire_duration=None)
Gets a variable from a cluster using a CAS operation.
- cas_increment(key, password=None, expire_duration=None)
Increments a variable in a cluster by using a CAS operation.
- cas_init(key, val=None, password=None, expire_duration=None)
Initializes a variable in a cluster by using a CAS operation.
- cas_set(key, old_val, new_val, password=None, expire_duration=None)
Sets a value in a cluster by using a CAS operation.
- clear_subkeys(key)
Clears subkeys of a key. Another subkeys that a subkey has will be removed recursively.
- close()
Closes the handle
- get(key, password=None)
Gets the value
- get_attributes(key, use_str=True)
Retrievs attributes of a key.
- get_subkeys(key, use_str=True)
Retrievs subkeys of a key.
- keyqueue_get(prefix, is_fifo=True, password=None, expire_duration=None)
Gets a new key/value element from queue.
- keyqueue_put(prefix, key, val, is_fifo=True, is_check_attr=True, password=None, expire_duration=None)
Adds a new key/value pair element to a queue.
- property libc
returns libc handle
- property libk2hdkc

Gets a new element to a queue.
- queue_put(prefix, val, is_fifo=True, is_check_attr=True, password=None, expire_duration=None)
Adds a new element to a queue.
- remove(key)
Removes a key from a cluster.
- remove_subkeys(key, subkeys, nested=False)
Removes a subkey from the current subkeys.
- rename(key, newkey, parent_key=None, is_check_attr=True, password=None, expire_duration=None)
Renames a key in a cluster.
- set(key, val, clear_subkeys=False, subkeys=None, password=None, expire_duration=None, time_unit=TimeUnit.SECONDS)
Sets a key/value pair
- set_subkeys(key, subkeys)
Replaces current subkeys with new one.
