Settings for establishing a connection to Nakadi.

Fields

stream_keep_alive_limit: usize

Maximum number of empty keep alive batches to get in a row before closing the connection. If 0 or undefined will send keep alive messages indefinitely.

stream_limit: usize

Maximum number of Events in this stream (over all partitions being streamed in this connection).

• If 0 or undefined, will stream batches indefinitely.
• Stream initialization will fail if stream_limit is lower than batch_limit.

stream_timeout: Duration

Maximum time in seconds a stream will live before connection is closed by the server.

If 0 or unspecified will stream indefinitely. If this timeout is reached, any pending messages (in the sense of stream_limit) will be flushed to the client. Stream initialization will fail if stream_timeout is lower than batch_flush_timeout.

batch_flush_timeout: Duration

Maximum time in seconds to wait for the flushing of each chunk (per partition).

• If the amount of buffered Events reaches batch_limit before this batch_flush_timeout is reached, the messages are immediately flushed to the client and batch flush timer is reset.
• If 0 or undefined, will assume 30 seconds.

batch_limit: usize

Maximum number of Events in each chunk (and therefore per partition) of the stream.

• If 0 or unspecified will buffer Events indefinitely and flush on reaching of batch_flush_timeout.

max_uncommitted_events: usize

The amount of uncommitted events Nakadi will stream before pausing the stream. When in paused state and commit comes - the stream will resume. Minimal value is 1.

nakadi_host: String

The URI prefix for the Nakadi Host, e.g. "https://my.nakadi.com"

request_timeout: Duration

The request timeout used when committing events

commit_strategy: CommitStrategy

The CommitStrategy to use

subscription_discovery: SubscriptionDiscovery

Used for discovering/creating the subscription to consume

min_idle_worker_lifetime: Option<Duration>

The time after which a worker that received no events will be shut down.
