2. Connection Information

2.1. Connection Sizes

Connection Instance Produced Consumed
I/O Messaging 4 or 8 bytes 4 or 8 bytes
Explicit Messaging 49 bytes 49 bytes
Notes
- For the Explicit Messaging connection, this is the maximum message length: shorter messages are also acceptable.
- For the Polled I/O connection, if the actual consumed data size is less than the connection instance’s
consumed_connection_size attribute, the consumed data will be ignored, but the connection will otherwise produce
normally. If the actual consumed data size is larger than the connection instance’s consumed_connection_size attribute,
the consumed data will be ignored and the connection will not produce.
