Is ACID a Priority or Not? Can MongoDB Decide?

By Ken Rugg
Can MongoDB make a decision?
If I’m honest, I think of MongoDB as more of a “data store” than an actual database. This may be a controversial opinion these days, but I don’t think it’s a hard position to support. Granted, MongoDB does a great job storing data for a particular use case and can be highly optimized for that purpose. But, as applications inevitably evolve, Mongo’s single-use case formula, where applications leverage the document store to optimize one access path to the data, starts to unravel.

Nested Subprocedures

By Jeevan Chalke
Planet image
As the name suggests, a nested subprocedure allows us to write a function or procedure nested within another function or procedure. It means a function can have another function within it, just like its own variable. And, as this inner function is part of the outer function, it has no visibility outside the function that encloses it.

Using force_parallel_mode Correctly

By Robert Haas
Are you using force_parallel_mode correctly?
I admit it: I invented force_parallel_mode. I believed then, and still believe now, that it is valuable for testing purposes. Certainly, testing using force_parallel_mode=on or force_parallel_mode=regress has uncovered many bugs in PostgreSQL's parallel query support that would otherwise have been...

Upgrade your Partitioning from Inheritance to Declarative

By Ashutosh Bapat
Partitioning
Before PostgreSQL 10, Postgres users partitioned their data using inheritance based partitioning. The method used constraints to define the partitions and rules or triggers to route the data to appropriate partition. A user had to write and maintain code for all of that. PostgreSQL 10 introduced...

By Ashutosh Bapat
Cost based optimization A query may be executed in many different ways, modeled as plans in the query optimizer, differing in resources required and/or execution time. A typical DBMS's query optimizer tries to find all of the possible plans for executing a given query and chooses the fastest plan...
