If a MySQL client or server wants to send data, it:

• Splits the data into packets of size (2²⁴−1) bytes

• Prepends to each chunk a packet header

Protocol::Packet

Data between client and server is exchanged in packets of max 16MByte size.

Payload

Type	Name	Description
int<3>	payload_length	Length of the payload. The number of bytes in the packet beyond the initial 4 bytes that make up the packet header.
int<1>	sequence_id	Sequence ID
string<var>	payload	[len=payload_length] payload of the packet

Example

A COM_QUIT looks like this:

* length: 1 * sequence_id: x00 * payload: 0x01
