NAME

Protocol::CassandraCQL - wire protocol support functions for Cassandra CQL3

DESCRIPTION

This module provides the basic constants and other support functions required to communicate with a Cassandra database using CQL3. 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.

TODO

  • Reimplement Protocol::CassandraCQL::Frame in XS code for better performance.

  • Support 64bit-challenged perls by using Math::BigInt for 64bit values
