Abstract
A method, a system, and a computer program product for performing accelerated and memory efficient similarity matching. A data stream having a plurality of data zones is received. Each zone includes a zone identifier. A plurality of hashing values for each zone are generated. Each hashing value is generated based on a portion of a zone. A storage structure having a plurality of storage containers is generated. Each storage container stores one or more hashing values associated with each respective storage container and a plurality of zone identifiers referencing the associated hashing values. At least one storage container includes a listing of zone identifiers stored in each storage container. Using the storage structure, the received data stream is deduplicated.
