flux-config-kvs(5)

DESCRIPTION

The Flux system instance kvs service provides the primary key value store (i.e. "the KVS") for a large number of Flux services. For example, job eventlogs are stored in the KVS.

The kvs table may contain the following keys:

KEYS

checkpoint-period

(optional) Sets a period of time (in RFC 23 Flux Standard Duration format) that the KVS will regularly checkpoint a reference to its primary namespace. The checkpoint is used to protect against data loss in the event of a Flux broker crash.

gc-threshold

(optional) Sets the number of KVS commits (distinct root snapshots) after which offline garbage collection is performed by flux-shutdown(1). A value of 100000 may be a good starting point. (Default: garbage collection must be manually requested with flux-shutdown --gc).

EXAMPLE

[kvs]
checkpoint-period = "30m"
gc-threshold = 100000
