Open source Microsoft SQL Server alternatives

ClickHouse, Inc.

“> I remember reading in the ClickHouse docs some time ago that it does not have DELETE functionality. Does this pose any problems with GDPR and data deletion requests? Altinity is fixing this. The project is called Lightweight Delete and it's for exactly the GDPR reason cited.…”

ClickHouse, Inc.

“I'd like to thank the creators of ClickHouse as i hope they are reading here. We've been using it since 2019 in a single server setup with billions of rows. No problems at all. And query speeds that seem unreal compared to MySQL and pg. As we did not want to go into the…”

Is ORM still an anti-pattern?

“There are tons of antipatterns out there. Often the production database is completely different from anything I can or want to set up on my local machine (E.g. it's a cluster of database type A, while my local dev env is a single node of type B. > But if data makes you…”

Is ORM still an anti-pattern?

“I personally am thankful for ORM in Laravel's Eloquent. I have requirements to always have a changing query which if done with raw sql can increase the maintenance effort drastically. I speak this because I also am maintaining a legacy project which uses raw SQL and it takes a…”

Milvus – An Open-Source Vector Similarity Search Engine

“It's not about the ML platform. It's about the ML scenarios. If you want to search thru a huge amount of unstructured data after vectorization tech (like deep learning), Milvus will help you a lot. Our users use Milvus in below scenarios: 1. Chemical molecules analysis,…”

Milvus – An Open-Source Vector Similarity Search Engine

“Milvus allows users to append vectors. Vectors are stored in multiple file slices. When a file slice reaches the threshold, Milvus will build the index for that file slice, and new data will be inserted into a new file slice. For details, please refer We are now working on the…”

The DuckDB Local UI

“That's one way of looking at it. To me this UI seems like both a useful tool and an advertisement. There's another way this could have gone. DuckDB Labs might have published the extension as providing official HTTP API for all to use. Then simultaneously MotherDuck would…”

The DuckDB Local UI

“I do not know much about DuckDB but it sure looks awesome. Something I haven't found yet is a small swiss army knife for time series type of data: system and network monitoring, sensors and market data. I usually put everything in Prometheus but it is awkward. I would really…”

PingCap TiDB Leaks

“I am reading this as a potential leak of almost every possible piece of metadata related to the operation and the business but a limited leak of customer data. This goes to show the benefit of maintaining separations between the control plane and the data plane. This site does…”

PingCap TiDB Leaks

“" TiDB Cloud meet SOC 1 Type 2, SOC 2 Type 2, SOC 3, ISO 27001, ISO 27701, PCI DSS, GDPR, and HIPAA standards and requirements." All those compliance meetings to gain all these badges; the results show”

Qdrant, the Vector Search Database, raised $28M in a Series A round

“Depends, short term there is a lot of experimentation and innovation in this space obviously. But long term what matters (for investors) is defensible moats. Most or these products look a bit like one trick ponies to me with some features that are extremely likely to be borrowed…”

Qdrant 1.7.0

“As another signal, check out this report by Streamlit, which shows the popularity of different vector databases among Streamlit apps: Faiss and Pinecone are at the top (disclosure: I'm from Pinecone). But Faiss isn't really a full-fledged vector DB. Pinecone is a managed option…”

Chroma: Ubisoft's internal tool used to simulate color-blindness

“> If you take 2 minutes to read the user guide of both softwares, the difference is obvious. > Reshade requires you to select the game executable and inject tools into the executable > Chroma does not require you to point to the game Did we read the same user guide? As per…”

Chroma: Ubisoft's internal tool used to simulate color-blindness

“> can be injected into any game without modifying any engine / game code This sentence is an oxymoron... Once you inject code, you have modified the original code. That isn't always possible or desired. If you take 2 minutes to read the user guide of both softwares, the…”

DBX

“Come on! This is one of the most remarkably run companies around today. They never do anything halfway. If you balk at $350, you either aren't their target market or you don't think very highly of Dropbox. $350 is about an hour and a half of work, at $215 per hour. That's chump…”

PostgREST

“> > And if you treat the database as the source of truth for managing data, then the idea of making it an application engine would be anathema. > Why? Could you elaborate more on that? Sure. Your previous declaration of: > We argue that all "business logic" is in fact "data…”

PostgREST

“I see what you mean. This is the view that considers that the database should only be a Persistence Layer and not a Processing Engine. There is a great talk[1] that @felixyz shared regarding the shortcomings of the Persistence Layer approach and the advantages of Processing…”

Valkey Turns One: Community fork of Redis

“> Nuance Not any random ensemble of "Valkey contributors" that did async IO but AWS: One of those cloud providers Redis moved away from FOSS for. One year later, Valkey hasn't just survived – it's thriving! The Async I/O Threading model contribution from AWS unlocked 3x+…”

Valkey Turns One: Community fork of Redis

“It’s a bit confusing to me exactly what went wrong. I think that when you have a redis/valkey cluster with multiple nodes and you use the cluster uri, there must be some kind of load balancer or custom routing. When we would attempt to connect to valkey the connection would look…”

Supabase is acquiring Turso

“Personally, I think SQLite is good enough, but in the current agent era, it doesn’t seem good enough anymore. For example, while I was writing semquery ( ), I kept looking for an embedded database that could simultaneously support SQL queries, vector queries, and graph database…”

Supabase is acquiring Turso

“No, I truly don't understand that. It is true that some acquisitions fail, but most of the ones you see failing are doomed from the start and are a way for the founder to exit, acquhire, etc. I had a never-ending host of options at my hand. Turso grew revenue > 5x this year. I…”

Dolt is Git for Data: a SQL database that you can fork, clone, branch, merge

“thanks for the mention of TerminusDB ( ) -> we are the graph cousins of Dolt. Great to see so much energy in the version control database world! We are currently focused on data mesh use cases. Rather than trying to be GitHub for Data, we're trying to be YOUR GitHub for Data.…”

Dolt is Git for Data: a SQL database that you can fork, clone, branch, merge

“Your final example is very like the data mesh ideas coming out of thought works and elsewhere ( ). Data products being owned by data producers and common data models ONLY when required. It is as much organizational model as technology, but I don't really think this maps to SQL…”

Multi-node TimescaleDB is now free

“One possible approach compatible with true software freedom and the usual definition of open source is not to restrict use of modified versions of the code, but instead to use naming to distinguish between the two, and only support the unmodified version. For example, the code…”

Multi-node TimescaleDB is now free

“We spent about 6 months looking at pretty much every database tech on the market, cockroach, clickhouse, influx, voltdb, memsql etc were top contenders, there was an outdated article on medium.com (by victoria metrics) which slammed TimescaleDB for its disk usage, we did not…”

RxDB – a real-time database on top of PouchDB

“The concept or RxDB, being able to iterate observables of your change stream, is great. Centering on schemas and typescript is as well. The broadcast channel based leader election also solved the common issue with Pouch where you can’t respond to real-time changes and update…”

RxDB – a real-time database on top of PouchDB

“I've experimented with RxDB in a side project of mine, a spaced-repetition web app that is designed to be usable offline, with background sync between clients. The offline-first requirement meant using something like IndexedDB to store state client-side, which is where RxDB…”

Ukraine is a major producer of neon gas, critical for lasers used in chipmaking

“Ukraine supplies 90% high grade semiconductor global neon from it's iron ore mines. Key iron ore mine locations have been ''annexed'' by recent Russian invasion - Crimea, etc. in a pincer like strategic configuration. Please see map Ninety per cent of neon production is in…”

Ukraine is a major producer of neon gas, critical for lasers used in chipmaking

“You seem to be right, it was a military-industrial move by the Soviet Union to counter the Strategic Defense Initiative (Star Wars). Having read a briefing describing the rocket involved, it Star Wars was cutting-edge 2060's technology that happened to be possible in the 80's…”

LowDB – A flat JSON file database

“Hi everyone, First, thanks for all the interest, it’s quite sudden and unexpected. Actually, LowDB is an extract from JSON Server, a mocking REST server based on plain JSON ( ). So, basically, it's not meant to be used in critical / intensive applications. Instead, it's much…”

LowDB – A flat JSON file database

“I do find a 'production' use case: I have a static site that uses Backbone to load a static json collection of pages. The json file itself is very small (less than 100k) and will not grow much with time. I built a small CMS to let me edit pages, the data for the CMS is dynamic…”

Quitting Dgraph Labs

“> I'm not sure what "eat section 13 of Mongo's license" means Buncha weeks ago I had a paranoid fit about the legalities of this app I wanna try to launch. I read some conserning things about the MongoDB license, mainly that the open source initiative didn't approve it bc Mongo…”

Quitting Dgraph Labs

“I worked for a company last year that chose Dgraph as its primary data store. Thanks to Dgraph's query language, we were able to implement a GraphQL API server that had no resolvers and no need for dataloader—the n+1 problem simply couldn't occur! It was like magic.…”
