Abstract: Systems and methods are disclosed to implement an indexing engine that maintains an index in an index store for a storage object in a data store. In embodiments, the index store may be implemented using an in-memory storage cluster separate from the data store. The storage object may have multiple indexes, which may have different filtering or sorting criteria for the data. In embodiments, updates to the storage object are received as an update stream by the indexing engine. Based on configurable indexing rules, the indexing engine applies the updates to the appropriate indexes. To service a query to the data store, a query engine first retrieves a set of keys satisfying the query from the index store, and then data corresponding to the keys from the data store or another index. In embodiments, the index may be refreshed via touch updates of selected data in the storage object.

Abstract: A transform execution service obtains a first request from a client device of a customer to execute a set of instructions. In response to the request, the service provides the set of instructions and a first set of credentials to a cluster of computer nodes. The cluster submits, to the service, a second request to assume an identity of the customer, where the second request demonstrates access to the first set of credentials. In response to the second request, the service provides a second set of credentials to cause the cluster to use the second set of credentials to access an identity management service to obtain a third set of credentials to exercise a set of permissions associated with the customer. The cluster uses the third set of credentials to exercise a subset of the set of permissions to access a set of resources to execute the set of instructions.

Abstract: Methods, systems, and computer-readable media for a transformation specification format for multiple execution engines are disclosed. A transformation specification is expressed according to a transformation specification format. The transformation specification represents a polytree or graph linking one or more data producer nodes, one or more data transformation nodes, and one or more data consumer nodes. An execution engine is selected from among a plurality of available execution engines for execution of the transformation specification. The execution engine is used to acquire data from one or more data producers corresponding to the one or more data producer nodes, perform one or more transformations of the data corresponding to the one or more data transformation nodes, and output one or more results of the one or more transformations to one or more data consumers corresponding to the one or more data consumer nodes.
