Struct SyncStateSet 

pub struct SyncStateSet {
    pub broker_name: String,
    pub master_broker_id: u64,
    pub master_addr: String,
    pub master_epoch: u64,
    pub sync_state_set: Vec<u64>,
    pub last_update_timestamp: u64,
}

Sync state set (In-Sync Replicas)

Tracks the set of replicas that are considered in-sync with the master. Similar to Kafka’s ISR (In-Sync Replica) concept.

Fields

broker_name: String

Broker name (identifies the broker set)

master_broker_id: u64

Master broker ID

master_addr: String

Master address

master_epoch: u64

Master epoch

sync_state_set: Vec<u64>

Sync state set (list of in-sync broker IDs)

last_update_timestamp: u64

Last update timestamp

Implementations

impl SyncStateSet

pub fn new( broker_name: String, master_broker_id: u64, master_addr: String, ) -> Self

pub fn contains(&self, broker_id: u64) -> bool

Check if a broker is in the sync state set

pub fn add_broker(&mut self, broker_id: u64)

Add a broker to the sync state set

pub fn remove_broker(&mut self, broker_id: u64)

Remove a broker from the sync state set

pub fn size(&self) -> usize

Get the size of the sync state set

pub fn is_master(&self, broker_id: u64) -> bool
