SYSTEMS AND METHODS FOR DATA MANAGEMENT AND QUERY OPTIMIZATION

Abstract: a central node can: receive a query comprising at least one parameter comprising a time range of a dataset stored in a cloud storage system; transmit one or more of the query parameters comprising the time range to a metadata service; receive from the metadata service a list of files related to the query; and assign to each processing node of a plurality of processing nodes a subset of the files. each processing node can: determine that the subset is not stored on a cache; retrieving the subset not stored on the cache from the cloud storage system; store the retrieved subset in a local memory; scan the subset stored in the local memory for data matching the at least one parameter to generate a subset of query results; and concurrently copy using a separate thread from the scanning, the subset stored in the local memory to the cache.
