NAME
Protocol::CassandraCQL - wire protocol support functions for Cassandra CQLv3
DESCRIPTION
This module provides the basic constants and other support functions required to communicate with a Cassandra database using CQLv3. It is not in itself a CQL client; it simply provides the necessary support functions to allow one to be written.
For a complete client, see instead Net::Async::CassandraCQL.
CONSTANTS
The following families of constants are defined, along with export tags:
OPCODE_* (:opcodes)
Opcodes used in message frames.
RESULT_* (:results)
Result codes used in OPCODE_RESULT frames.
TYPE_* (:types)
Type codes used in TYPE_ROWS and TYPE_PREPARED column metadata.
CONSISTENCY_* (:consistencies)
Consistency levels used in OPCODE_QUERY and OPCODE_EXECUTE frames.
FUNCTIONS
$name = typename( $type )
Returns the name of the given TYPE_* value, without the initial TYPE_ prefix.
$b = encode( $type, $v )
$v = decode( $type, $b )
Encode or decode a bytestring for a CQL value of the given type.
TODO
Reimplement Protocol::CassandraCQL::Frame in XS code for better performance.
Use something faster than dynamic method dispatch for
encode()anddecode().Codecs for TYPE_UUID, TYPE_INET
More robust testing of data types, arguments to methods, etc...
