oxigraph VS quickwit

oxigraph

I am currently building a single-node graph database implementing the SPARQL query language. It is written in Rust and is named Oxigraph: https://github.com/oxigraph/oxigraph

I would love to get help, I have a working MVP but there are a lot of work left to get good performances for which I would love help. Some current problems are:

I've recently had to use KDE from Ubuntu 18.04 (Plasma 5.12) and my daily driver is Arch Linux with the current 5.24 beta. Improvement in Plasma is really incredible. Kudos to everyone contributing to make it better. It's such a stable and powerful system.

What's still lacking is unfortunately the application side: baloo indexer ist still a mess that hogs cpu and likes to corrupt itself every other day. Replaced it with mlocate. KDE Mail, Organizer, Akonadi are very powerful concepts and ideas and I hope some talented devs take on them and make them more stable and robust. The approach to use PostgreSQL/MySQL on the desktop has failed maybe there is a lighter way i.e. something like oxigraph (https://github.com/oxigraph/oxigraph) for implementing the Nepomuk/ Semantic Desktop ideas in a fast and stable way. For now I'm using evince and evolution for mail and reading PDFs.

Still hugs and love to everyone involved in Plasma I can't imagine using anything else and lately I'm replacing GNOME with Plasma everywhere I'm allowed to.

Oxigraph might be suitable https://github.com/oxigraph/oxigraph. It has bindings for Python and JavaScript.

I am currently working on an embeddable graph database. It uses the SPARQL query language. It's still WIP but I believe some people already use it on Android. https://github.com/oxigraph/oxigraph

Hi folks, Quickwit cofounder here.

We started Quickwit 3 years ago with a POC, "Searching the web for under $1000/month" (see HN discussions [0]), with the goal of making a robust OSS alternative to Elasticsearch / Splunk / Datadog.

We have reached a significant milestone with our latest release (0.7) [1], as we have witnessed users of the nightly version of Quickwit deploy clusters with hundreds of nodes, ingest hundreds of terabytes of data daily, and enjoy considerable cost savings.

To give you a concrete example, one company is ingesting hundreds of terabytes of logs daily and migrating from Elasticsearch to Quickwit. They divided their compute costs by 5x and storage costs by 2x while increasing retention from 3 to 30 days. They also increased their durability, accuracy with exactly-once semantics thanks to the native Kafka support, and elasticity.

The 0.7 release also brings better integrations with the Observability ecosystem: improvements of the Elasticsearch-compatible API and better support of OpenTelemetry standards, Grafana, and Jaeger.

Of course, we still have a lot of work to be a fully-fledged observability engine, and we would love to get some feedback or suggestions.

To give you a glance at our 2024 roadmap, we planned to focus on Kibana/OpenDashboard integration, metrics support, and pipe-based query language.

We tested S3 Express for our search engine quickwit[0] a couple of weeks ago.

While this was really satisfying on the performance side, we were a bit disappointed by the price, and I mostly agree with the article on this matter.

I can see some very specific use cases where the pricing should be OK but currently, I would say most of our users should just stay on the classic S3 and add some local SSD caching if they have a lot of requests.

Hi HN, I’m one of the builders of Quickwit, a cloud-native OSS search engine for observability. As of 2023, we support logs and traces, metrics will come in 2024.

You know the pitch: while software like Datadog or Splunk are great, they often comes with hefty price tags. Our mission is to offer an affordable alternative. So we’ve built Quickwit, we’ve made it compatible with the observabilty ecosystem (OpenTelemetry, Jaeger, Grafana) and above all, we’ve made it cost-efficient / “easy” to scale (well it’s never easy to scale to petabytes..).

To give you a glance at the engine performance I made a benchmark on the GitHub Archive dataset, 23 TB of events, here are the main observations:

Indexing: costs $2 per ingested TB. With 4CPU, throughput is at 20MBs However, you'll observe > 30MB throughput on simpler datasets, like logs and traces.

Search: a typical query costs $0.0002 per TB (considering both CPU time and GET request costs). Using 8CPU, a simple query on 23TB is achieved in under a second.

Storage: on S3, it costs $8 per ingested TB per month on the GitHub Archive dataset. With logs and traces, you might see costs around $5/ingested TB due to a 2x better compression ratio.

I'm eager to get your thoughts on this!

Quickwit (https://quickwit.io/) | Paris, France | Onsite and remote (based in Europe) | Full-time

The company is fully remote but we also have a small office in Paris. We prefer candidates based in Europe but can make exceptions for the right profiles.

- Senior Software Engineer 80-110k€ + 0.25-1% equity based on experience.

    We’re looking for a senior software engineer to contribute to [Quickwit](https://github.com/quickwit-oss/quickwit), our open-source search and analytics engine. We have an ambitious roadmap for the next 18 months (performance optimization, distributed storage, support for SQL, query optimizer, revamp of our execution engine, etc.), and this is a great opportunity to shape the future of Quickwit while tackling fun and challenging problems in the field of distributed databases.

In our latest blog post, we walk you through the steps of instrumenting your Rust application and monitoring the performance on Grafana using Quickwit + Jaeger.
