RequestHeader
The request header contains the ApiId, ApiVersion, and hasMetaData flag to indicate whether the request contains some metadata.
...
| ResponseHeader => (ResponseTypeId | ErrorCode) hasMetaData CorrelationId | Description |
|---|---|
| ResponseTypeId => fixedSize = 2 bytes, type = int16 | |
| hasMetaData => fixedSize = 1 byte, type = boolean | if there is any meta data associated with this request |
| CorrelationId => fixedSize = 4 bytes, type = int32 |
Error Format
The response will indicate the error using the fixed size error header, optional metadata and error message.

| ErrorCode => fixedSize = 2 bytes, type = int16 | When there is error response will have message(String) for it |
| hasMetaData => fixedSize = 1 byte, type = boolean | if there is any meta data associated with this request |
| CorrelationId => fixedSize = 4 bytes, type = int32 |
Value
The Value is serialized bytes for the Geode region value. It contains value header and series of bytes. Using value header, we can send a large number of bytes big serialized object in more than one chunk.
