As Jon already commented the most, just some thoughts from me.

Regarding SQL, the processing of blocks of 1000 records involves stuff way beyond anything one could reasonably expect to be able to do from SQL.

Some programs I’ve written lately process much larger “blocks” of relational information - mostly JOINed tables (de-normalized/flattened) - and do anything inside the database, that seems to be a good job for the database - like summarizing, counting, calculations, and so on.

The database engine is quite good in optimization - 99% of the time, much better, than what any programmer can do manually.

Most people underestimate what one can do with modern (!!) SQL - and with modern I mean 1999 and newer stuff like OLAP-window functions.

Just my 2 cents.

Regards,
Daniel
