Abstract: In a computer-implemented method for cardinality-based index caching of time series data, a cardinality of an index of a time series data monitoring system is determined. The cardinality of the index is compared to a cardinality threshold. Responsive to determining that the cardinality of the index exceeds the cardinality threshold, the index is cached in a local memory cache of a query node of the times series data monitoring system. Responsive to determining that the cardinality of the index does not exceed the cardinality threshold, the index is cached in a distributed memory cache of the times series data monitoring system.

Abstract: Common timeline processing techniques for generating unique manifests are described herein. In accordance with various embodiments a method is performed at one or more servers that include one or more processors, one or more non-transitory memory, and one or more network interfaces. The method includes receiving a request from a client for a unique manifest, wherein the request indicates a recording timeline and includes a recording identifier (ID). The method further includes constructing the unique manifest in response to the request according to the recording timeline, including obtaining at least a portion of the unique manifest from a cache in accordance with determining a corresponding portion of the recording timeline exists in the cache. The method additionally includes appending the recording ID of the request to a URL prefix in the unique manifest. The method also includes sending the unique manifest to the client.
