The economy scaling policy prioritizes cost efficiency over performance by keeping existing clusters fully loaded rather than automatically starting additional clusters. This conserves credits by minimizing the number of active clusters, though it may result in query queuing and longer completion times. The community discussion shows unanimous consensus (100% of votes) for option D, with the top-voted comment explicitly stating that economy mode 'conserves credits by favoring keeping running clusters fully-loaded rather than starting additional clusters.' Options A, B, and C describe benefits of the standard scaling policy, which prioritizes performance by quickly scaling out to handle concurrent queries, rather than the economy policy's cost-saving focus.
