Package io.aeron.archive Description

The aeron-archive is a module which enables Aeron data stream recording and replay from persistent storage.

Features:

Record: service can record a particular subscription, described by <channel, streamId>. Each resulting image for the subscription will be recorded under a new recordingId. Local network publications are recorded using the spy feature for efficiency.
Extend: an existing recording by appending.
Replay: service can replay a recorded recordingId from a particular position and length.
Query: the catalog for existing recordings and the recorded position of an active recording.
Truncate: allows a stopped recording to have its length truncated, and if truncated to the start position then it is effectively deleted.
Replicate: allows the replication of a stream from a source to destination archive with the option to continue after catching up and merging with a live multicast stream.
Replay Merge: allows a late joining subscriber of a recorded stream to replay a recording and then merge with the live multicast stream for cut over if the consumer is fast enough to keep up.
