    Abstract: Real time detection of anomalies may be implemented for a data stream. A data stream may receive data records as input. An evaluation of the data records may be performed as the data records are received utilizing an anomaly detection model that is dynamically generated for a time period that includes the data records. A responsive action may be performed in response to detecting various anomalies, such as providing a notification of the anomaly, requesting a corrective action, invoking further analysis of the detected anomaly. Evaluations of the data record and responsive actions may be performed as specified by a user, in some embodiments.

    Abstract: A configuration request comprising a security option selected for a particular data stream is received. Nodes of a plurality of functional categories, such as a data ingestion category and a data retrieval category are to be configured for the stream. The security option indicates a security profile of a resource to be used for nodes of at least one functional category. In accordance with the configuration request, a node of a first functional category is configured at a resource with a first security profile, and configuration of a node of a second functional category is initiated at a different resource with a different security profile.

    Abstract: Automated reconfiguration of real time data stream processing may be implemented. A processing function that describes one or more operations to be performed with respect to one or more data streams may be executed at one or more processing nodes. Performance metrics describing the performance of the processing function at the processing nodes may be collected and monitored. A reconfiguration event may be detected for the processing function. A different execution configuration for the processing function may be determined and initiated in response to detecting the reconfiguration event.

    Abstract: Managed function execution for processing data streams in real time may be. A function that describes one or more operations to be performed with respect to one or more data streams may be received via programmatic interface for a managed stream processing system. Stream processing nodes capable of applying the function may be determined and execution of the one or more operations may be initiated at the stream processing nodes as data records of the data stream are received. Results of the application of the processing function may be provided to one or more destinations specified for the function. Performance metrics may also be collected for the execution of the function and provided to a client that submitted the function.

    Abstract: A stream management system may implement dynamic management of a data stream. Utilization data of different partitions of a data stream may be tracked. When routing a data record received at the stream management system, a partition may be dynamically identified for the data recorded. The data record may then be directed to the identified partition. Other management operations, such as repartitioning the data stream or reassigning resources for processing data records in the data stream may be performed based on the utilization data tracked for the partitions.

    Abstract: A programmatic interface is implemented, enabling a client of a stream management service to select a data ingestion policy for a data stream. A client request selecting an at-least-once ingestion policy is received. In accordance with the at-least-once policy, a client may transmit an indication of a data record one or more times to the service until a positive acknowledgement is received. In response to receiving a plurality of transmissions indicating a particular data record, respective positive acknowledgements are sent to the client. Based on a persistence policy selected for the stream, copies of the data record are stored at one or more storage locations in response to one particular transmission of the plurality of transmissions.

    Abstract: Idempotent processing of data may be implemented for data records retrieved from a data stream. A data stream may receive data records as input and distribute the ingestion, storage, and processing of the data records amongst one or more partitions of the data stream. Partition metadata may be maintained which includes checkpoint metadata for retrieving, processing, and sending data records in the data stream to a specified destination. When assigned a partition for processing, checkpoint metadata for partition may be accessed to determine whether a pending checkpoint for the partition exists. If not pending checkpoint exists, new data records may be retrieved, processed, and sent from the partition of the data stream to a specified destination. If a checkpoint is pending, then the data records identified by the checkpoint metadata as pending may be retrieved, processed, and sent to the specified destination.
