1. A system comprising:
a storage system storing a plurality of database tables;
a buffer cache; and
a computer server to:
receive a request to fetch a first dataset associated with one or more of the database tables, the request including a first identifier associated with the first dataset;
determine a first signature associated with the first dataset by application of a locality-sensitive hashing algorithm to the first identifier and respective identifiers of one or more datasets fetched contemporaneously with the first dataset; and
determine, by comparing a distance between the first signature and a second signature associated with a second dataset, whether to update a first link associating the second dataset with the first dataset, the link indicating that the first dataset should be prefetched and stored in the buffer cache in response to reception of a request to fetch the second dataset.
