A reader's backlog is at risk

Weik.io 2026.2

A reader's oldest waiting event is getting close to the age at which the channel's stream deletes it.

What it means#

The events a reader hasn’t handled yet are getting old enough that the channel’s stream may delete them before the reader gets to them.

What raises it#

The oldest waiting event is older than half of what its stream keeps, for a stream that is more than nine tenths full, or it’s within 3 days of the stream’s age limit.

What to check#

See each reader with how far it has come:

Terminal
$ weikio get readers --env <environment> --integration <project>/<integration>

See the environment’s streams with their usage and limits:

Terminal
$ weikio get streams --env <environment>

How to fix it#

Get the reader to catch up, as for a reader that is behind, before the stream deletes the events. A platform administrator can also give the environment’s events more room with weikio env set <environment> --events-bytes <size>.
