Abstract: Embodiments include methods, and computer program products of an analytical workflow system. Aspects include: observing analytical workflow patterns of one or more users to gather statistics, predicting an analytical workflow and parameter values likely to be requested in future based on the observations according to a compilation policy, applying a parameter generation policy and preparing the predicted analytical workflows according to the compilation policy, and executing analytical workflows and deploying the executed analytical workflows according to a deployment policy. The aspects also include: refining an analytical workflow specification, reusing prepared, executed or deployed analytical workflows, and terminating one or more prepared, executed or deployed analytical workflows when these analytical workflows are unlikely to be requested by a user in the near future according to a termination policy.
