This is a little difficult for SPL,SPL is a little versatile. For example, it can be used as middleware to solve mixed computing over multiple data sources, Implement hot-swap microservices, Substitute stored procedure, Act as a data warehouse for high performance, As a computing engine for implementing the true lakehouse, accompany with OLTP database to achieve low-risk HTAP, ..., It can even be used as an Excel plugin to help with desktop analysis. Because computing is everywhere! Everyone only cares about their own issues, that's a fraction of what SPL is used for. But we can't predict what people will care when they come to the homepage, we have to list a little bit of everything, so, the home page is somewhat cluttered. Simply skip the items you are not interested in and read the links to the items you are interested in. Thanks very much.
