MetadataProviderReloadingAttributes

The following attributes are common to all reloading "batch-oriented" metadata providers (i.e., FileBackedHTTPMetadataProvider, FilesystemMetadataProvider, and ResourceBackedMetadataProvider):

Name

Type

Default

Description

Name

Type

Default

Description

minRefreshDelay

Duration

PT30S

Lower bound on the next refresh from the time calculated based on the metadata's expiration

maxRefreshDelay

Duration

PT4H

Upper bound on the next refresh from the time calculated based on the metadata's expiration

refreshDelayFactor

Real Number (strictly between 0.0 and 1.0)

0.75

A factor applied to the initially determined refresh time in order to determine the next refresh time (typically to ensure refresh takes place prior to the metadata's expiration). Attempts to refresh metadata will generally begin around the product of this number and the maximum refresh delay.

expirationWarningThreshold

Duration

PT0S (disabled)

For each attempted metadata refresh (whether or not fresh metadata is obtained), if requireValidMetadata is true, and there is a validUntil XML attribute on the document root element, and the difference between validUntil and the current time is less than expirationWarningThreshold, the system logs a warning about the impending expiration.

indexesRef

Bean ID



Bean ID of a Set<MetadataIndex> used to support resolution of metadata based on criteria other than an entityID, e.g. resolving by protocol endpoint for CAS or by SAML Artifact source ID.

resolveViaPredicatesOnly

Boolean

false

Flag indicating whether resolution may be performed solely by applying predicates to the entire metadata collection, when an entityID input criterion is not supplied

parserPoolRef

Bean ID

shibboleth.ParserPool

Identifies a Spring bean for the XML parser used to parse metadata. Generally should not be changed.

taskTimerRef

Bean ID



Identifies a Spring bean containing a Java Timer used to schedule reloads. When not set, an internal one is created. Generally should not be changed.
