Apache Pulsar: Pulsar or Kafka?

Pulsar separates storage from compute and covers queuing and streaming in one system. Kafka has a far larger ecosystem and hiring pool. Most teams should have a specific reason before choosing Pulsar.

Turso: What are the overage charges on Turso plans?

Overage charges vary by tier. Free tier charges $0.75/GB for storage overage and $1 per billion rows over the 500M limit. Developer tier charges $0.75/GB storage and $1 per billion rows. Scaler tier charges $0.50/GB and $0.80 per billion rows. Pro tier charges $0.45/GB and $0.75 per billion rows.

Apache Pulsar: Why does separated storage matter?

Brokers hold no data, so adding or replacing one requires no rebalancing, and storage can grow without adding serving capacity.

Turso: Is there a free tier on Turso?

Yes, Turso's free tier includes 100 databases, 5 GB storage, and 500 million monthly rows read with overage charges for excess usage.
