What common mistake do developers make with Memory awareness, why does the mistake cause problems, and what is the safer approach?

What common mistake do developers make with Memory awareness, why does the mistake cause problems, and what is the safer approach? One recurring problem with memory awareness is applying it without understanding the boundary it protects. Choosing pagination only by UI preference and ignoring the database ordering and index needed to make large result sets efficient. In addition, Pagination and chunking are tools for controlling application memory and database workload, not substitutes for proper indexes. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
