Abstract: A database system may use asymmetric hardware for analytics nodes. In some embodiments, a database system includes a replica set comprising a plurality of base nodes and at least one analytics node. The analytics nodes may have asymmetric hardware respective to the base nodes. The base nodes may include a primary node and two secondary nodes. The primary node may be configured to accept writes and propagate the writes to secondary nodes and may also propagate writes to analytics nodes. Secondary nodes may replicate writes and accept reads. Analytics nodes may perform data analysis operations. Analytics nodes may have a first instance size different than a second instance size of the base nodes.
