<p>Co-founder of Quickwit here.  Seeing our acquisition by Datadog on the HN front page feels like a truly full-circle moment.<p>HN has been interwoven with Quickwit's journey from the very beginning. Looking back, it's striking to see how our progress is literally chronicled in our HN front-page posts:<p>- Searching the web for under $1000/month [0]<p>- A Rust optimization story [1]<p>- Decentralized cluster membership in Rust [2]<p>- Filtering a vector with SIMD instructions (AVX-2 and AVX-512) [3]<p>- Efficient indexing with Quickwit Rust actor framework [4]<p>- A compressed indexable bitset [5]<p>- Show HN: Quickwit – OSS Alternative to Elasticsearch, Splunk, Datadog [6]<p>- Quickwit 0.8: Indexing and Search at Petabyte Scale [7]<p>- Tantivy – full-text search engine library inspired by Apache Lucene [8]<p>- Binance built a 100PB log service with Quickwit [9]<p>- Datadog acquires Quickwit [10]<p>Each of these front-page appearances was a milestone for us. We put our hearts into writing those engineering articles, hoping to contribute something valuable to our community.<p>I'm convinced HN played a key role in Quickwit's success by providing visibility, positive feedback, critical comments, and leads that contacted us directly after a front-page post. This community's authenticity and passion for technology are unparalleled. And we're incredibly grateful for this.<p>Thank you all :)<p>[0] <a href="https://news.ycombinator.com/item?id=27074481">https://news.ycombinator.com/item?id=27074481</a><p>[1] <a href="https://news.ycombinator.com/item?id=28955461">https://news.ycombinator.com/item?id=28955461</a><p>[2] <a href="https://news.ycombinator.com/item?id=31190586">https://news.ycombinator.com/item?id=31190586</a><p>[3] <a href="https://news.ycombinator.com/item?id=32674040">https://news.ycombinator.com/item?id=32674040</a><p>[4] <a href="https://news.ycombinator.com/item?id=35785421">https://news.ycombinator.com/item?id=35785421</a><p>[5] <a href="https://news.ycombinator.com/item?id=36519467">https://news.ycombinator.com/item?id=36519467</a><p>[6] <a href="https://news.ycombinator.com/item?id=38902042">https://news.ycombinator.com/item?id=38902042</a><p>[7] <a href="https://news.ycombinator.com/item?id=39756367">https://news.ycombinator.com/item?id=39756367</a><p>[8] <a href="https://news.ycombinator.com/item?id=40492834">https://news.ycombinator.com/item?id=40492834</a><p>[9] <a href="https://news.ycombinator.com/item?id=40935701">https://news.ycombinator.com/item?id=40935701</a><p>[10] <a href="https://news.ycombinator.com/item?id=42648043">https://news.ycombinator.com/item?id=42648043</a></p>

<p>Indeed. They benefit from a discount, but we don't know the discount figure.<p>To further reduce the storage costs, you can use S3 Storage Classes or cheaper object storage like Alibaba for longer retention. Quickwit does not handle that, so you need to handle this yourself, though.</p>

<p>Good question.<p>Let's estimate the costs of compute.<p>For indexing, they need 2800 vCPUs[1], and they are using c6g instances; on-demand hourly price is $0.034/h per vCPU.
So indexing will cost them around $70k/month.<p>For search, they need 1200 vCPUs, it will cost them around $30k/month.<p>For storage, it will cost them $23/TB * 20000 = $460k/month.<p>Storage costs are an issue. Of course, they pay less than $23/TB but it's still expensive. They are optimizing this either by using different storage classes or by moving data to cheaper cloud providers for long term storage (less requests mean you need less performant storage and usually you can get a very good price on those object storages).<p>On quickwit side, we will also improve the compression ratio to reduce the storage footprint.<p>[1]: I fixed the num vCPUs number of indexing, it was written 4000 when I published the post, but it corresponded to the total number of vCPUs for search and indexing.</p>

<p>If you don't need vector search and have very large Elasticsearch deployment, you can have a look at Quickwit, it's a search engine on object storage, it's OSS and works for append-only datasets (like logs, traces, ...)<p>Repo: <a href="https://github.com/quickwit-oss/quickwit">https://github.com/quickwit-oss/quickwit</a></p>

<p>Quickwit is an alternative with a strong focus on scalability (max we have seen is 40PB) with a decoupled compute and storage architecture. But we do only logs and traces for now.<p>Repository: <a href="https://github.com/quickwit-oss/quickwit">https://github.com/quickwit-oss/quickwit</a>

<p>This is awesome; we need this kind of alternative to overpriced software like Splunk. We built and open-sourced Quickwit to see this kind of tool built on top of it.<p>We will follow Tracecat closely. I'm convinced this will impact our roadmap, and I'm happy to receive any feedback so you can get the most out of Quickwit for Tracecat.<p>Good luck, guys!!!</p>

<p>Thanks! Quickwit is the distributed engine built on top of tantivy,  we basically separated compute and storage for search, I wrote this blog post to introduce the architecture: <a href="https://quickwit.io/blog/quickwit-101" rel="nofollow">https://quickwit.io/blog/quickwit-101</a><p>PS: it’s tantivy!!!</p>
