Statistical metadata for every data chunk — min, max, start time, end time — stored in TsFile format by Apache IoTDB database.
The query engine uses this to skip irrelevant blocks entirely, accelerating time-range scans.

B-trees dominate traditional RDBMS like PostgreSQL, MySQL,Optimized for read-heavy workloads:fast,efficient range queries. LSM trees excel at high-write throughput but sacrifice read speed & simplicity—hence not universally adopted

Get to know PostgreSQL’s Free Space Map (FSM)! 🧠 Nikhil Sontakke explains why the FSM is critical for efficient storage management. **"AWSM FSM!"** #PostgreSQL #FSM #DatabaseInternals
Also open to article/thread/resource recommendations! 🙌

Skip the left-most index bottleneck. 🎯
Our latest blog post (Part 2) explores Skip Scan in PostgreSQL 18 and how it empowers you to use existing indexes even when the leading column isn’t in the query.

Bloom filters is a very powerful data structure that is used in many databases.
It’s also an important data structure to understand when it comes to designing high scale systems.
Here we are with our next video in the #DatabaseInternals series - Bloom Filters 101
In the next video we will talk about some advanced features such as deleting items, scalable bloom filters, cuckoo filters etc.
Like, repost and share it for the love of Databases and Data structures. Link below 👇

TL;DR:
🔹 Logs = sequential record of changes.
🔹 Backups = disk-based snapshots.
🔹 Checkpoints = the bridge that reduces recovery time by syncing logs to backups.
This balance of durability, speed, and recovery is why modern databases are so reliable. 💪

Just released the episode on pg_duckdb with @JelteF on The GeekNarrator. If you love #Postgres or #DuckDb or just #DatabaseInternals, this episode will be interesting for you.
Give it a watch here and learn, how DuckDB can make your Postgres better..

I implemented:
✅ Thread-safe reads/writes with sync.RWMutex
✅ Metadata tracking (size, blocks, timestamps)
✅ A structure to log reads/writes
Wrote a blog post about it https://t.co/Hw9GL14do6
follow along! Let’s learn, build. 🙌
