Is PostgreSQL good enough?

-

tldr; you can do jobs, queues, real time change feeds, time series, object store, document store, full text search with PostgreSQL. How to, pros/cons, rough performance and complexity levels are all discussed. Many sources and relevant documentation is linked to.

Your database is first. But can PostgreSQL be second?
Web/app projects these days often have many distributed parts. It's not uncommon for groups to use the right tool for the job. The right tools are often something like the choice below.
Redis for queuing, and caching.Elastic Search for searching, and log stash.Influxdb or RRD for timeseries.S3 for an object store.PostgreSQL for relational data with constraints, and validation via schemas.Celery for job queues.Kafka for a buffer of queues or stream processing.Exception logging with PostgreSQL (perhaps using Sentry)KDB for low latency analytics on your column oriented data.Mongo/ZODB for storing documents JSON (or mangodb for /dev/null replacement)  SQLite for embedded. Ne…

Experiments with new low latency PyPy garbage collector in a thread.

TLDR; less performance spikes, faster average performance, PyPy is a good Python for games and multimedia apps on desktop systems, running GC in a thread is a good idea for GIL releasing apps.
In March 2018 at the PyPy winter sprint I spent some days working on improving pygame support on PyPy. Part of this was investigating pypy frame drop. In there I found PyPy had both lower average performance in this pygame-using-CPython-API benchmark, and had spikes which caused frame drops. Remember that in latency sensitive applications performance spikes are not allowed. Note that not very much of this code is pure python (where PyPy is fastest), so it's almost a worst case benchmark for PyPy performance.

Thanks to Antonio, the PyPy team and their supporters — things have much improved since then. One improvement in particular is that PyPy now allows more control of when the Garbage Collection does its work. Read more about it in the blog post "PyPy for low latency systems".

🐱‍🏍 — the first pygame 2 community game. Starting now! Are you in?

-
What is a 🐱‍🏍? *[0].


There was this email thread on the pygame mailing list.
"About Pygame development".
One topic of that conversation was doing a community game in there for reasons(see below).
I would like to do a pygame 2 community game to submit in the: - https://ldjam.com/ - https://itch.io/jam/game-off-2018 (GameOff github jam)
Ludumdare(ldjam) starts in 3 days, 7 hours. Theme not selected yet. GameOff finishes in 4 days 2 hours. Theme is "Hybrid", Jam already started.
So, the Jams finish in 4.1 days. Are you in?  If so join the web based chatroom(discord) in the "#communitygame" channel. Our repo: https://github.com/pygame/stuntcat
I'm trying to form a team now.

So why do this? My reasons for doing this are to push me to get pygame 2 features done that are actually useful in apps (Write Games, Not Engines). It will be a good testbed for prototypi…
