As shown in the following diagram, the hot data cluster is the operational cluster running in production for serving the enterprise applications:
Also, for the purpose of aiding offline data analysis, in other words, for analysts to run data simulations with no overhead for the customer SLA, the data can be synchronized from the hot data cluster to the warm data cluster using daemons. This is so that analysts can run their analysis and build models using the latest datasets. The warm data cluster will be analogous to the hot data cluster in terms of the technology stack to keep it in sync and consistent, so that the ...
