Scalable architectures for reference signature matching and updating

A non-transitory computer-readable storage medium comprising instructions that, when executed, cause a processor to perform operations comprising:

• providing a query representative of monitored media to a plurality of computer nodes;
• processing the query at each of the plurality of computer nodes to determine a target computer node based on an output generated by at least one computer node among the plurality of computer nodes, wherein the target computer node is configured to store reference data characterizing reference media, and wherein each computer node of the plurality of computer nodes is configured to process the query in parallel with each other node of the plurality of computer nodes;
• and
• identifying the monitored media based on the query and the reference data stored at the target computer node.
