Configuration for a publication that does not change during it’s lifetime.

Fields

channel: *const c_char

Media address for delivery to the channel.

This returns a pointer only valid for the lifetime of the publication.

original_registration_id: i64

The registration used to register this Publication with the media driver by the first publisher.

registration_id: i64

Get the registration id used to register this Publication with the media driver.

If this value is different from the original_registration_id then a previous active registration exists.

max_possible_position: i64

The maximum possible position this stream can reach due to its term buffer length.

Maximum possible position is term-length times 2^31 in bytes.

position_bits_to_shift: usize

Number of bits to right shift a position to get a term count for how far the stream has progressed.

term_buffer_length: usize

Get the length in bytes for each term partition in the log buffer.

max_message_length: usize

Maximum message length supported in bytes. Messages may be made of multiple fragments if greater than MTU length.

max_payload_length: usize

Maximum length of a message payload that fits within a message fragment.

This is the MTU length minus the message fragment header length.

stream_id: i32

Stream id of the publication.

session_id: i32

Session id of the publication.

initial_term_id: i32

The initial term id assigned when this publication was created. This can be used to determine how many terms have passed since creation.

publication_limit_counter_id: i32

Counter id for the publication limit.

channel_status_indicator_id: i32

Counter id for the channel status indicator
