Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. Individual processes generate WAL records, and latency is very crucial for transactions. Modern compression algorithms and libraries are excellent.

In 2016, I released the first version of the tool, then called not Statoscope, but Webpack Runtime Analyzer. It might not be completely efficient if we use modules in raw form, as they are in the file system: there might be some doubles, some modules could be combined, and others are only partially used.

We are now ready to start the query scan, perform some early phase processing, and start the first additional parallel tasks. The query processor begins execution by starting the query scan process via a call to CQueryScan::StartupQuery. That might be easy to comprehend, but it wouldn’t be very efficient in general.

This eliminated unnecessary row-mode processing, and removed the need for an exchange. SQL Server 2016 introduced serial batch mode processing and aggregate pushdown. All column segments within a row group must be implicitly sorted the same way so SQL Server can efficiently reconstruct complete rows from the column segments.
