Native replication configuration.

Fields

enabled: bool

Enable native mutation-stream replication.

role: ReplicationRole

Runtime role for this process.

bind_addr: String

Address a primary listens on for replicas and service subscribers.

replica_of: Option<String>

Primary address a replica connects to.

auth_token: Option<String>

Optional plaintext authentication token for native replication.

compression: ReplicationCompression

Compression algorithm for mutation batches and snapshot chunks.

zstd_level: i32

zstd compression level used when compression = "zstd".

send_policy: ReplicationSendPolicy

Send policy for primary mutation flushes.

batch_max_records: usize

Maximum records in one mutation batch.

batch_max_bytes: usize

Maximum uncompressed bytes in one mutation batch.

batch_max_delay_us: u64

Maximum time a non-empty batch may wait before flush.

backlog_bytes: usize

Approximate retained in-memory backlog size for partial catch-up.

snapshot_chunk_bytes: usize

Snapshot chunk size before compression.

queue_capacity: usize

Per-shard bounded queue capacity for ready replication batches.

The shard worker builds ordered mutation batches locally. When this queue is full, that shard’s emitting thread blocks until its exporter drains a batch. Increase this if export lanes cannot keep up with bursty writes.

max_replicas: usize

Maximum simultaneously-connected replicas in listen mode.

connect_timeout_ms: u64

Maximum time spent opening one TCP connect attempt from a replica.

write_timeout_ms: u64

Per-write timeout for replication TCP I/O.

reconnect_backoff_ms: u64

Delay between reconnect attempts after a replica disconnect.

subscriber_channel_capacity: usize

Per-subscriber outbound channel capacity.
