No matter which data sources are involved, cross-database or other source, as long as the data source can be connected and accessed, the subsequent operations are always the same because SPL provides the unified data object: table sequence and cursor.😍😇 dev.to/esproc_spl/cro…

We use orders table as an example to achieve esProc SPL data externalization to speed up regular filtering operation and grouping & aggregation operation.The same example,SQL took 11 seconds, while SPL took 2.2 seconds.🧐👇🫰 dev.to/esproc_spl/pra…

SQL COUNT DISTINCT has been slow. It is, in essence, a grouping operation, which keeps traversed grouping field values. When the result set is too large, the data needs to be written to the hard disk and buffered, resulting in low performance. SPL ...👇👏 dev.to/esproc_spl/pra…
