User data, such as cache keys and values, is represented in Ignite Binary Object format. Binary Object can be a primitive (predefined type) or a complex object.
Primitives (predefined types)
Primitives are represented as a type code + value:
...
Available primitives are listed below:
| Name | Type Code | Size (bytes) |
|---|---|---|
| byte | 1 | 1 |
| short | 2 | 2 |
| int | 3 | 4 |
| long | 4 | 8 |
| float | 5 | 4 |
| double | 6 | 8 |
| char | 7 | 2 |
| bool | 8 | 1 |
| string | 9 | 4 bytes length + length * 2 |
| UUID (Guid) | 10 | 8 |
| date | 11 | 8 |
| byte | ||
| array | 12 | 4 bytes length + length |
| short array | 13 | 4 bytes length + length * 2 |
| int array | 14 | 4 bytes length + length * 4 |
| long array | 15 | 4 bytes length + length * 8 |
| float array | 16 | 4 bytes length + length * 4 |
| double array | 17 | 4 bytes length + length * 8 |
| char array | 18 | 4 bytes length + length * 2 |
| bool array | 19 | 4 bytes length + length |
| string array | 20 | 4 bytes length + variable length strings, see above |
| UUID (Guid) array | 21 | 4 bytes length + length * 8 |
| date array | 22 | 4 bytes length + length * 8 |
TODO
Message format
All messages, request and response, including handshake, start with int message length (excluding these first 4 bytes). E.g. empty message would be represented by 4 zero bytes.
