Online query execution using a big data framework

A non-transitory, computer-readable medium having instructions stored thereon that are executable by a server system to perform operations comprising:

• accessing a distributed computing system that includes a plurality of computing nodes, wherein the distributed computing system includes:
• a distributed storage system operable to store transaction data associated with a plurality of users;
• and
• a distributed computing engine operable to perform distributed processing jobs based on the transaction data;
• preemptively creating a first compute session on the distributed computing engine, wherein the first compute session provides access to one or more functionalities of the distributed computing engine;
• subsequent to the preemptively creating the first compute session, receiving, from a client device, a first data request associated with a first user of the plurality of users;
• using the first compute session, executing, by the distributed computing engine, a query associated with the first data request against the transaction data to retrieve a results dataset;
• and
• sending the results dataset to the client device within a predetermined time threshold after the first data request is received by the server system wherein the results dataset corresponds to a simulation of one or more fraud detection filters based on the transaction data.

A server system, comprising:

• a distributed computing system that includes a plurality of computing nodes, wherein the distributed computing system includes:
• a distributed storage system operable to store transaction data associated with a plurality of users;
• and
• a distributed computing engine operable to perform distributed processing jobs based on the transaction data;
• at least one processor;
• and
• a non-transitory, computer-readable medium having instructions stored thereon that are executable by the at least one processor to cause the server system to:
• preemptively creating a first compute session on the distributed computing engine, wherein the first compute session provides access to one or more functionalities of the distributed computing engine;
• subsequent to preemptively creating the first compute session, providing, to a client device, interface data for a simulation user interface that is operable to graphically depict simulated results of modifications to fraud detection filters;
• receive, from the client device, a first data request associated with a first user of the plurality of users, wherein the first data request is a first simulation request to simulate a modified version of a first fraud detection filter utilized by the first user;
• using the first compute session, execute, by the distributed computing engine, a query associated with the first data request against the transaction data to retrieve a results dataset;
• and
• send the results dataset to the client device.
