etcd limits: requests and storage
Request size limit
etcd is designed to handle small key value pairs typical for metadata. Larger requests will work, but may increase the latency of other requests. By default, the maximum size of any request is 1.5 MiB. This limit is configurable through
--max-request-bytes flag for etcd server.
Storage size limit
The default storage size limit is 2 GiB, configurable with
--quota-backend-bytes flag. 8 GiB is a suggested maximum size for normal environments and etcd warns at startup if the configured value exceeds it.
