Geo-Distribution in YugabyteDB: Engineering Around the Physics of Latency

Customers today expect always-on, highly responsive access to services wherever they are in the world. This is driving businesses to deploy globally distributed applications that deliver better customer experiences. Moving to a geo-distributed database is a key part of this. Moving data closer to where the end-users are enables lower latency access. Geo-distribution can make the data service resilient to zone and region failures in the cloud.

Reads in YugabyteDB – Tuning Consistency, Latency and Fault Tolerance

Introduction

YugabyteDB is built primarily to be a CP database per the CAP theorem. It supports two interfaces – YSQL for SQL workloads and YCQL for Cassandra-like workloads. In this blog, we will primarily talk about the YCQL interface. When an application interacts with the database using the YCQL interface, the writes are always consistent and reads are consistent by default.
