ChEMBL is a large-scale drug discovery database containing bioactivity information primarily extracted from scientific literature.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…
