EloqDoc: MongoDB-compatible doc DB with object storage as first citizen
We're excited to share EloqDoc, a new open source document database built on top of Data Substrate. EloqDoc is designed around the principle of treating object storage (like S3) as a first-class citizen for durability and cost efficiency. If you love the flexibility of MongoDB's document model but are struggling with scaling, cost, and consistency due to its coupled architecture, EloqDoc is for you. It’s built to solve MongoDB's inherent infrastructure challenges while remaining fully compatible with existing MongoDB clients and drivers. Key Features: 1. Object Storage as First Citizen: Uses…
In plain words
EloqDoc is an open-source document database that uses object storage like S3 as its primary durability layer while maintaining MongoDB compatibility. It decouples compute and storage for independent scaling, reducing infrastructure costs through object storage and local NVMe caching instead of traditional block storage. Built on Data Substrate, EloqDoc addresses MongoDB's scaling and consistency limitations while remaining fully compatible with existing MongoDB clients and drivers, making it suitable for teams seeking a more cost-efficient and scalable document database.

We're excited to share EloqDoc, a new open source document database built on top of Data Substrate. EloqDoc is designed around the principle of treating object storage (like S3) as a first-class citizen for durability and cost efficiency. If you love the flexibility of MongoDB's document model but are struggling with scaling, cost, and consistency due to its coupled architecture, EloqDoc is for you. It’s built to solve MongoDB's inherent infrastructure challenges while remaining fully compatible with existing MongoDB clients and drivers. Key Features: 1. Object Storage as First Citizen: Uses object storage for primary durability, leveraging local NVMe caching to achieve both lower cost and higher performance than using block-level storage (e.g. EBS). 2. Decoupled Compute & Storage: Scale your compute/QPS independently of your storage capacity, or vice-versa, without data movement. 3. True ACID Transactions: Delivers full ACID compliance with especially fast distributed transactions—consistency without compromise. 4. Native Distribution & Multi-Writer: It's a natively distributed database, eliminating complex manual sharding routers (like mongos) and supporting true Multi-Writer scalability.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
