In response to a first programmatic request, metadata indicating that a first isolated read channel of a real-time category has been associated with a first target stream is stored at a stream management service. In response to another request, metadata indicating that a second isolated read channel of a non-real-time category has been associated with a second target stream is stored. In response to a read request indicating the first channel or the second channel, one or more data records of the corresponding target streams are provided.

Isolated read channel categories at streaming data service

At a data stream management service, a first set of metadata indicating that a first isolated read channel has been associated with a first data stream is stored. The first isolated read channel has an associated read performance limit setting. A second set of metadata indicating that a second isolated read channel, with its own performance limit setting, has been associated with a data stream is also stored. Based on determining that the difference between a metric of read operations associated with the first channel and the read performance limit setting of the first channel meets a first criterion, the service initiates a throttling operation for reads associated with the first channel. The throttling decision is made independently of read metrics of the second channel.

Streaming data service with isolated read channels

From a stream management service, indications of transmissions of data records of a first data stream via a persistent network connection associated with a subscription are provided to a stream processing application. In response to detecting that a transfer throttling condition associated with the subscription has been met, a delay is introduced before additional data records are transmitted via the same persistent network connection. After a subscription expiration period has elapsed, an indication of the expiration is provided to the application via the persistent connection.

Stream data record reads using push-mode persistent connections

At a stream management service, one or more storage servers of a first repository are assigned to store at least a first partition of a first data stream. At the first repository, records of different partitions are interleaved. In response to determining that a set of data records of the first partition meet a first criterion, a rearranged version of the set in which the data records of the first partition are contiguous is stored at a second repository. Using the rearranged version, one or more records of the first partition are provided to an application which meets a lag criterion.

Optimization techniques to support lagging readers at streaming data service

In response to a first programmatic request, metadata indicating that a first isolated read channel associated with a data stream has been established is stored at a stream management service. A read request that indicates the first isolated read channel and the stream is obtained. In response to the read request, contents of data records of the stream are provided.
