How PlanetScale migrates databases in the petabyte range with zero downtime by Matt Lord: planetscale.com/blog/zero-down…

📈How do you scale a database from small to huge? Vertical scaling, replication, and sharding are commonly used techniques on the journey to scale. Our most recent video gives an overview these challenges and how Vitess solves them all. youtube.com/watch?v=O3EK7e…

In a large database, the cost of IOPS and throughput can add up quickly. Sharding can help mitigate these rising costs by spreading out your workload across many servers. dub.sh/iops

Database Insights Recommendation View from PlanetScale

We just added a new metric to Insights: max_latency. This column show the maximum response time of any individual query pattern in the selected time window. Maximum is a useful metric for spotting extreme outliers that may not show up in p99 (99th percentile).

In this blog post series, Shlomi Noach covers design considerations for a database system throttler whose purpose is to keep the database system healthy. The series will cover metrics, granularity, behavior, impact, prioritization, and more. planetscale.com/blog/anatomy-o…

Been working on this for 2 months, and it's finally ready to share! This piece not only *describes* how B-trees and database indexes work, but gives you the opportunity to interact with them, reinforcing the concepts, and providing a bit of fun along the way. Link in thread.

⚡️ Handy trick: run `pscale ping` to list the latency of every region based on your own location.

We recently added a feature to PlanetScale Insights that allows you to track your index usage on a per-query basis. Check out our latest YouTube video for an overview. youtube.com/watch?v=ZD7a1b…

Migrating your database to a new provider is a delicate and stressful process. Our proof-of-concept phase is designed to instill confidence that PlanetScale is the right solution via thorough testing and fulfillment of your success criteria. If you want to see sharding, we

We've made sharding even easier. Check out our redesigned cluster configuration page:
