=head1 DESCRIPTION
=item MEMCACHED_BEHAVIOR_NO_BLOCK
Causes libmemcached(3) to use asychronous IO. This is the fastest transport
-available.
+available for storage functions. For read operations it is currently
+similar in performance to the non-blocking method (this is being
+looked into).
=item MEMCACHED_BEHAVIOR_TCP_NODELAY
=item MEMCACHED_BEHAVIOR_HASH
-Makes the default hashing algorithm for keys use MD5. The value can be set to either MEMCACHED_HASH_DEFAULT, MEMCACHED_HASH_MD5, MEMCACHED_HASH_CRC, MEMCACHED_HASH_FNV1_64, MEMCACHED_HASH_FNV1A_64, MEMCACHED_HASH_FNV1_32, MEMCACHED_HASH_FNV1A_32, MEMCACHED_HASH_KETAMA. The behavior for all hashes but MEMCACHED_HASH_DEFAULT is identitical to the Java driver written by Dustin Sallings.
+Makes the default hashing algorithm for keys use MD5. The value can be set

+=item MEMCACHED_BEHAVIOR_DISTRIBUTION
+
+Using this you can enable different means of distributing values to servers.
+The default method is MEMCACHED_DISTRIBUTION_MODULA. You can enable
+consistent hashing by setting MEMCACHED_DISTRIBUTION_CONSISTENT.
+Consistent hashing delivers better distribution and allows servers to be
+added to the cluster with minimal cache losses. Currently
+MEMCACHED_DISTRIBUTION_CONSISTENT is an alias for the value
+MEMCACHED_DISTRIBUTION_CONSISTENT_KETAMA.
=item MEMCACHED_BEHAVIOR_CACHE_LOOKUPS
Support CAS operations (this is not enabled by default at this point in the server since it imposes a slight performance penalty).
+=item MEMCACHED_BEHAVIOR_KETAMA
+
+Sets the default distribution to MEMCACHED_DISTRIBUTION_CONSISTENT_KETAMA
+and the hash to MEMCACHED_HASH_MD5.
+
=item MEMCACHED_BEHAVIOR_POLL_TIMEOUT
Modify the timeout value that is used by poll(). The default value is -1. An signed int pointer must be passed to memcached_behavior_set() to change this value. For memcached_behavior_get() a signed int value will be cast and returned as the unsigned long long.
+=item MEMCACHED_BEHAVIOR_USER_DATA
+
+This allows you to store a pointer to a specifc piece of data. This can be
+retrieved from inside of memcached_fetch_execute(). Cloning a memcached_st
+
+will copy the pointer to the clone. This was deprecated in 0.14 in favor
+of memcached_callback_set(3). This will be removed in 0.15.
+
+=item MEMCACHED_BEHAVIOR_BUFFER_REQUESTS
+
+Enabling buffered IO causes commands to "buffer" instead of being sent. Any
+action that gets data causes this buffer to be be sent to the remote
+connection. Quiting the connection or closing down the connection will also
+cause the buffered data to be pushed to the remote connection.
+
+=item MEMCACHED_BEHAVIOR_VERIFY_KEY
+
+Enabling this will cause libmemcached(3) to test all keys to verify that they
+are valid keys.
+
+=item MEMCACHED_BEHAVIOR_SORT_HOSTS
+
+Enabling this will cause hosts that are added to be placed in the host list in
+sorted order. This will defeat consisten hashing.
+
+=item MEMCACHED_BEHAVIOR_CONNECT_TIMEOUT
+
+In non-blocking mode this changes the value of the timeout during socket
+connection.
=back
memcached_behavior_get() returns either the current value of the get, or 0
or 1 on simple flag behaviors (1 being enabled). memcached_behavior_set()
-returns whether or not the behavior was enabled.
+returns failure or success.
+
+=head1 NOTES
+
+memcached_behavior_set() in version .17 was changed from taking a pointer
+to data value, to taking a uin64_t.
