How Plume Handled Billions of Operations Per Day Despite an AWS Zone Outage

Enterprises deploy YugabyteDB clusters across multiple availability zones (AZs) in order to ensure continuous availability of their business-critical services even when faced with cloud infrastructure failures like zone outages. On November 12, 2019, there was one such outage of an entire availability zone in the eu-central-1 region of AWS. This was reported on the AWS status page on that day,

What is Distributed SQL?

SQL has been the de-facto language for relational databases (aka RDBMS) for almost four decades. Relational databases are therefore also known as SQL databases. However, the original SQL databases like Oracle, PostgreSQL and MySQL are monolithic from an architectural standpoint. They are unable to distribute data and queries across multiple instances automatically. NewSQL databases emerged to make SQL scalable. However,

The Benefit of Partial Indexes in Distributed SQL Databases

If a partial index is used, instead of a regular one, on a nullable column—where only a small fraction of the rows have not null values for this column—then the response time for inserts, updates, and deletes can be shortened significantly. As a bonus, the response times for single row selects shorten a little bit too. This post explains what a partial index is,

How YugabyteDB Scales to More than 1 Million Inserts Per Sec

There are a number of well-known experiments where eventually-consistent NoSQL databases were scaled out to perform millions of inserts and queries. Here, we do the same using YSQL, YugabyteDB’s PostgreSQL-compatible, strongly-consistent, distributed SQL API. We created a 100-node YugabyteDB cluster, ran single-row INSERT and SELECT workloads with high concurrency – each for an hour and measured the sustained performance (throughput and latency).
