Abstract: Methods, systems, and computer-readable storage media for receiving, from a first entity, a first call, the call being received by a middleware client of a second entity, storing a set of headers associated with a workflow in a request context holder of the middleware client, and determining that a second call is to be executed from the middleware client of the second entity for the workflow, and in response: reading, by a client of the middleware client, the set of headers associated with the workflow, including the headers in a request of the second call, determining an endpoint for the second call, and transmitting the second call for receipt at the endpoint.

Abstract: Methods, systems, and computer-readable storage media for receiving metric data of a cloud system periodically; transforming the metric data of each type into a byte array using mapping tables, wherein the byte array is an encoded format of the metric data, where each field of the metric data is encoded as a field ID and a field type ID that are short integer variables; merging and storing the byte arrays of multiple metric data into a binary file, wherein the binary file comprises multiple blocks with each block comprising multiple byte arrays; generating indexes for common fields of different metric data in the binary file; receiving a retrieval request requesting metric records including a common field of a particular value; determining storage locations of one or more metric records satisfying the retrieval request; and obtaining the one or more metric records from the binary file using the corresponding storage locations.
