Abstract
An indexing service uses a distributed data storage service to store a file comprising a subset of a plurality of data points. The indexing service also stores metadata indicative of a range of keys associated with the data points, and a data structure comprising information indicative of a probability that the file comprises data points associated with a first key. A client device, in response to a query for data points associated with the first key, downloads the file based on the range of keys and the probability. The client device searches the downloaded file for data points associated with the first key.
