#FoundationDB: A Distributed Database That Can't Be Killed https://thenewstack.io/foundationdb-a-distributed-database-that-cant-be-killed/

Just merged our first SQL query using #ApacheDataFusion at work! 🎉 Integrating it was a fantastic experience, It will soon be part of the core of #Materia.

Wrote about why DataFusion is a game-changer for #Rustlang #database systems: https://pierrezemb.fr/posts/thank-you-datafusion/

👀 Ever wonder how services like #Apple's #CloudKit handle massive datasets on #FoundationDB despite its 5s transaction limits?

🔬 My new post dives into the FDB Record Layer's continuation mechanism

#Jepsen: Amazon RDS for PostgreSQL 17.4 https://jepsen.io/analyses/amazon-rds-for-postgresql-17.4

🚀 Had some fun hacking together a new TUI (with @ratatui_rs) to dig into the #FoundationDB #simulation framework!

It visualizes nemesis workloads like:
⚡ Attrition
🌐 Network Splits
⏳ Induced Latencies

Let's start day 2 of #BugBash

Today I will be at #bugbash in Washington DC!

I just published a new blogpost "Debugging #FoundationDB's Data Distributor" https://pierrezemb.fr/posts/fdb-data-distributor/

✍️ Just released a new article: "Ensuring Safety in #foundationdb's #rustlang crate"

👀 Check it out here: https://pierrezemb.fr/posts/providing-safety-fdb-rs/

Wow, a conference with a totally insane speaker list on my birthday? Thanks 🤩

I will be at #bugbash in Washington next April 🐛

Some metrics in #zookeeper have surprisingly amusing names 😂

👑 Is zookeeper trully loyal to me?

Spent this morning digging into a #ApacheFlink job in production. I just love this technology, both in development and operation. Give it a try!

https://flink.apache.org/

🚀 The #rustlang crate #foundationdb has now surpassed 2 million downloads, with an average of around 15k downloads per day.
🎉 Thank you to everyone who has supported and contributed!

I just published "Redwood’s memory tuning in #FoundationDB"
https://pierrezemb.fr/posts/redwood-memory-tuning/

📈 Milestone achieved! Clever Cloud's metric system has now exceeded 30TB of data before replication and compression 🚀

🔧 Leveraging #Warp10
and #FoundationDB has been key for handling this scale efficiently 😎

🚀 #p99 read latency under 1ms is always good to see!
🙏 Thank you #FoundationDB

@urcadox at least now, it is not stored in #Hbase 🤭

🚀 Did you know? Clever Cloud
's cutting-edge infrastructure is producing a whopping 2TB of telemetry every week (pre-replication)!

🔐 Safely and joyfully stored using the powerful combo of #warp10io
and #FoundationDB ✨#timeseries #infrastructure

Sometimes, the devil's lies in the details. Having a #distsys capable of diagnosis itself is such a relieve 🤩
```
Performance limited by process: Storage server performance (storage queue)
```
Thanks #FoundationDB

@emk there is an high probability I’ll try to mix them both 🙃
We are currently writing distributed databases in #Rust at #CleverCloud, so we are planning to do a blogpost series about this. But for now, I’m searching for something that can written now.

Time to do my #Introduction

My name is Pierre, I'm a senior software engineer living in Brest, France 🇫🇷

My main programming languages are #java and #rust

I have built/operated/contributed to a number of distributed systems such as #HBase, #Kafka, #Pulsar, #ETCD 👨‍💻

I'm now building #serverless #databases on top of #FoundationDB in a european cloud provider called Clever Cloud ☁️

You might also see some #squash screenshots by following me 💪

Feel free to reach out 🤝
