Existing dbSize shows physically allocated DB size and the backend (boltdb) won't shrink it after a compaction until a user runs the defrag command. The new dbSizeInUse shows the DB size that excludes free pages created by compactions so that users can see the actual DB usage. dbSize >= dbSizeInUse is always true. Note that dbSizeInUse shows a page-based size and not byte level usage.
Documentation
etcd is a distributed key-value store designed to reliably and quickly preserve and provide access to critical data. It enables reliable distributed coordination through distributed locking, leader elections, and write barriers. An etcd cluster is intended for high availability and permanent data storage and retrieval.
Getting started
New etcd users and developers should get started by downloading and building etcd. After getting etcd, follow this quick demo to see the basics of creating and working with an etcd cluster.
Developing with etcd
The easiest way to get started using etcd as a distributed key-value store is to set up a local cluster.
- Setting up local clusters
- Interacting with etcd
- gRPC etcd core and etcd concurrency API references
- HTTP JSON API through the gRPC gateway
- gRPC naming and discovery
- Client and proxy namespacing
- Embedding etcd
- Experimental features and APIs
- System limits
Operating etcd clusters
Administrators who need a fault-tolerant etcd cluster for either development or production should begin with a cluster on multiple machines.
