Project mention: A list of SaaS, PaaS and IaaS offerings that have free tiers of interest to devops and infradev | dev.to | 2024-02-05netdata.cloud — Netdata is an open-source tool to collect real-time metrics. It's a growing product and can also be found on GitHub!
One of the challenges Redis labs here have is that there's very little reason for their userbase to stay loyal to them.
antirez retired from Redis development a few years ago.
From https://github.com/redis/redis/graphs/contributors it looks like activity since he left has been mostly from people who didn't overlap with him much.
Redis Labs have not shown themselves to be outstanding stewards of the project as far as I can tell. Why shouldn't people support the fork?
Project mention: TimescaleDB: An open-source time-series SQL database | news.ycombinator.com | 2024-02-06
Changelog line items is probably a better measure (assuming the line items are aligned to features and bugfixes and not just a list of PRs) https://github.com/valkey-io/valkey/releases
Maybe version number/release cadence is also helpful.
Project mention: SPQR 1.3.0: a production-ready system for horizontal scaling of PostgreSQL | news.ycombinator.com | 2024-03-25
I am trying to recreate work from https://cstack.github.io/db_tutorial/ Basically it is recreating very simple SQLite, loading data from a file at the start of the program, and storing data in memory when the program runs then saving data to a file when we close the program. I believe that my issues are connected to working in the Windows instead of the Linux. Right now I am at part 5 when we start saving our data to the file when we close our program.
Project mention: Best Practice: use the same datatypes for comparisons, like joins and foreign keys | dev.to | 2024-02-01It is possible to apply Batched Nested Loop but with additional code that checks the range of the outer bigint and compare it only if it matches the range of integer. This has been added in YugabyteDB 2.21 with #20715 YSQL: Allow BNL on joins over different integer types to help migrations from PostgreSQL with such datatype inconsistencies.
Astro DB is powered by LibSQL, an open source fork of SQLite that was created by Turso. You can use Astro DB's drop-in database to build features like blogs, comment functionality, forums, feedback systems, and user authentication.
Project mention: Ask HN: It's 2023, how do you choose between MySQL and Postgres? | news.ycombinator.com | 2023-05-11Friends don't let their friends choose Mysql :)
A super long time ago (decades) when I was using Oracle regularly I had to make a decision on which way to go. Although Mysql then had the mindshare I thought that Postgres was more similar to Oracle, more standards compliant, and more of a real enterprise type of DB. The rumor was also that Postgres was heavier than MySQL. Too many horror stories of lost data (MyIsam), bad transactions (MyIsam lacks transaction integrity), and the number of Mysql gotchas being a really long list influenced me.
In time I actually found out that I had underestimated one of the most important attributes of Postgres that was a huge strength over Mysql: the power of community. Because Postgres has a really superb community that can be found on Libera Chat and elsewhere, and they are very willing to help out, I think Postgres has a huge advantage over Mysql. RhodiumToad [Andrew Gierth] https://github.com/RhodiumToad & davidfetter [David Fetter] https://www.linkedin.com/in/davidfetter are incredibly helpful folks.
I don't know that Postgres' licensing made a huge difference or not but my perception is that there are a ton of 3rd party products based on Postgres but customized to specific DB needs because of the more liberalness of the PG license which is MIT/BSD derived https://www.postgresql.org/about/licence/
Some of the PG based 3rd party DBs:
Enterprise DB https://www.enterprisedb.com/ - general purpose PG with some variants
Greenplum https://greenplum.org/ - Data warehousing
Crunchydata https://www.crunchydata.com/products/hardened-postgres - high security Postgres for regulated environments
Citus https://www.citusdata.com - Distributed DB & Columnar
Timescale https://www.timescale.com/
Why Choose PG today?
If you want better ACID: Postgres
If you want more compliant SQL: Postgres
If you want more customizability to a variety of use-cases: Postgres using a variant
If you want the flexibility of using NOSQL at times: Postgres
If you want more product knowledge reusability for other backend products: Postgres
Project mention: C# program not able to open or connect to an encrypted SQLite Database | /r/sqlite | 2023-04-30DB4S provides only one algorithm based on official SQLite cipher. You can encrypt your database with another in SQLiteStudio or sqlite-gui (I'm an author). Both applications use SQLite3 Multiple Ciphers-library.
Project mention: Marmot: Multi-writer distributed SQLite based on NATS | news.ycombinator.com | 2023-12-11If you're interested in this, here are some related projects that all take slightly different approaches:
- LiteSync directly competes with Marmot and supports DDL sync, but is closed source commercial (similar to SQLite EE): https://litesync.io
- dqlite is Canonical's distributed SQLite that depends on c-raft and kernel-level async I/O: https://dqlite.io
- cr-sqlite is a Rust-based loadable extension that adds CRDT changeset generation and reconciliation to SQLite: https://github.com/vlcn-io/cr-sqlite
Slightly related but not really (no multi writer, no C-level SQLite API or other restrictions):
- comdb2 (Bloombergs multi-homed RDMS using SQLite as the frontend)
- rqlite: RDMS with HTTP API and SQLite as the storage engine, used for replication and strong consistency (does not scale writes)
- litestream/LiteFS: disaster recovery replication
- liteserver: active read-only replication (predecessor of LiteSync)
Project mention: Can I learn Python while practicing writing queries for SQL simultaneously? I've recently completed learning SQL and trying to get better at it. | /r/SQL | 2023-05-10You can practice both by using https://www.psycopg.org from your Python code to communicate with your database. When I wanted to practice some SQL, that's what I did (we use psycopg at work, so that's what I practiced with, making a dream journal thingy for myself that was better than just noting stuff in a notepad because I could then look up e.g. what other stuff was correlated with Y, how many times I dreamed of X, etc. etc.)
hey hn, supabase ceo here
we've been fans of Oriole for a while now and have been long-time supporters
in case you're jumping straight to the comments: OrioleDB is a table storage extension for Postgres. it acts as a drop-in replacement for the default postgres storage engine using the Table Access Method APIs (pluggable storage). the storage engine changes the representation of table data on disk. its architecture is designed to take advantage of modern hardware like SSDs and NVRAM. it implements MVCC, the feature that allows allows multiple connected users to see different versions of the data depending on when their transaction started, via an UNDO log rather than tuple versioning.
one caveat: it requires several patches to the postgres core to expand on the type of features external storage engines extensions can implement. for this reason it could be a while before you see this land as a default engine on supabase. we will probably make it available as an option for customers who want to experiment - no timeline is decided yet.
finally, we have been working with the team on decoupled storage and compute [0]. this is experimental but promising, especially with some recent advances in S3 (specifically Express One Zone [1]). we have a demonstration in the blog post.
i'll message Alexander in case there are any technical questions

You can create a MySQL backup for Railway.app using the MyDumper tool or by using a backup service like SimpleBackups. Both methods involve generating a dump file that can be used for restoration.
This tutorial explains how to backup PostgreSQL database using pgBackRest and S3.
