US Patent 11954531 Use of relational databases in ephemeral computing nodes

A method comprises: storing, by a computing system, a relational data in a data lake; spinning-up, by an orchestration system of the computing system, an ephemeral computing node on a computing device of the computing system; importing, by the ephemeral computing node, a copy of the relational data from the data lake into a relational database management system (RDBMS) installed on the ephemeral computing node; after importing the copy of the relational data into the RDBMS, performing, by the ephemeral computing node, a computing process that runs within the RDBMS and that uses the copy of the relational data; and after completion of the computing process on the ephemeral computing node, spinning-down, by the orchestration system, the ephemeral computing node.
