Struct nats::jetstream::StreamConfig [−][src]
StreamConfig
determines the properties for a stream.
There are sensible defaults for most. If no subjects are
given the name will be used as the only subject.
Fields
name: String
A name for the Stream. Must not have spaces, tabs or period .
characters
max_bytes: i64
How large the Stream may become in total bytes before the configured discard policy kicks in
max_msgs: i64
How large the Stream may become in total messages before the configured discard policy kicks in
discard: DiscardPolicy
When a Stream has reached its configured max_bytes
or max_msgs
, this policy kicks in.
DiscardPolicy::New
refuses new messages or DiscardPolicy::Old
(default) deletes old messages to make space
subjects: Option<Vec<String>>
Which NATS subjects to populate this stream with. Supports wildcards. Defaults to just the
configured stream name
.
retention: RetentionPolicy
How message retention is considered, Limits
(default), Interest
or WorkQueue
max_consumers: isize
How many Consumers can be defined for a given Stream, -1 for unlimited
max_age: isize
Maximum age of any message in the stream, expressed in microseconds
max_msg_size: Option<i32>
The largest message that will be accepted by the Stream
storage: StorageType
The type of storage backend, File
(default) and Memory
num_replicas: usize
How many replicas to keep for each message in a clustered JetStream, maximum 5
no_ack: Option<bool>
Disables acknowledging messages that are received by the Stream
duplicate_window: Option<isize>
The window within which to track duplicate messages.
template_owner: Option<String>
The owner of the template associated with this stream.
