Module with constants for Cassandra type codes.
|
|
|
|
These constants are useful for
|
|
|
|
a) mapping messages to cqltypes (cassandra/cqltypes.py)
|
|
b) optimized dispatching for (de)serialization (cassandra/encoding.py)
|
|
|
|
Type codes are repeated here from the Cassandra binary protocol specification:
|
|
|
|
0x0000 Custom: the value is a [string], see above.
|
|
0x0001 Ascii
|
|
0x0002 Bigint
|
|
0x0003 Blob
|
|
0x0004 Boolean
|
|
0x0005 Counter
|
|
0x0006 Decimal
|
|
0x0007 Double
|
|
0x0008 Float
|
|
0x0009 Int
|
|
0x000A Text
|
|
0x000B Timestamp
|
|
0x000C Uuid
|
|
0x000D Varchar
|
|
0x000E Varint
|
|
0x000F Timeuuid
|
|
0x0010 Inet
|
|
0x0020 List: the value is an [option], representing the type
|
|
of the elements of the list.
|
|
0x0021 Map: the value is two [option], representing the types of the
|
|
keys and values of the map
|
|
0x0022 Set: the value is an [option], representing the type
|
|
of the elements of the set
