Query Service Indexer

To query your data, the Query service uses an indexer to index your RDF resources; i.e., the the Query service returns results only from the indexed RDF resources.

To index your data, the indexer requires Read access to the resources to be indexed. You can grant Read access specifically to the indexer using its WebID. The indexer has a WebID of the following form:

https://fragments-indexer.{ESS DOMAIN}/id

In addition, like any other agent, the indexer has Read access to those resources with Read access granted to the Public.

Indexing Data

Once the indexer is given Read access to a Resource, a Resource change notification triggers the indexing of that Resource.

Important Because the resource indexing occurs after the indexer consumes a resource change notification event, the query results may lag behind the current state of the Resource. The delay amount depends on the lag in the notification queue.

See also INRUPT_FRAGMENTS_INGEST_IGNORE_ERRORS .

Indexer Configuration

Note Whitespaces are preserved when parsing comma-delimited lists (i.e., the parsed string values are not trimmed). For example, when parsed, "value1, value2,value3 " results in "value1" , " value2" , "value3 " .

INRUPT_AUTHZ_AS_URI

The URI of the UMA Authorization Server .

The value must match the INRUPT_UMA_ISSUER configuration for UMA Service.

INRUPT_FRAGMENTS_INGEST_IGNORE_ERRORS

Default : false

A boolean that determines whether the indexer should log but continue on error or throw an exception on error:

  • Set to true to log the error and continue when the indexer encounters an error.

  • Set to false to throw an exception on error. (Default)

INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW

Default : inrupt,smallrye.jwt.encrypt.key.id,smallrye.jwt.encrypt.key.location,smallrye.jwt.sign.key.location,quarkus.mongodb.database

A comma-separated list of configuration property prefixes ( case-sensitive ) that determine which configurations are logged:

When specifying the prefixes, you can specify the prefixes using one of two formats:

Warning

Use the same format for both INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW and INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY .

For example, if you change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW, change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY as well.

Tip To avoid allowing more than desired configurations, specify as much of the prefix as possible. If the prefix specifies the complete prefix term, include the term delineator. For example:

  • If using dot-notation, if you want to match configuration properties of the form foobar.<xxxx>... , specify foobar. (including the dot . ) instead of, for example, foo or foobar .

  • If using converted form, if you want to match configuration properties of the form FOOBAR_<XXXX>... , specify FOOBAR_ (including the underscore _ ) instead of, for example, FOO or FOOBAR .

INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY

Default : inrupt.kafka

A comma-separated list of configuration name prefixes ( case-sensitive ) that determines which configurations (that would otherwise match the INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW ) are not logged. That is, INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY acts as a filter on INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW . For example:

  • If foobar. is an allowed prefix, to suppress foobar.private.<anything> , you can specify foobar.private. to the deny list.

  • If foobar. is not an allowed prefix, no property starting with foobar. is logged. As such, you do not need to specify foobar.private to the deny list.

When specifying the prefixes, you can specify the prefixes using one of two formats:

Warning Use the same format for both INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW and INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY .

For example, if you change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW, change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY as well.

INRUPT_LOGGING_REDACTION_NAME_ACTION

Default : REPLACE

Type of the redaction to perform. Supported values are:

Action
Description

REPLACE

Default. Replaces the matching text with a specified replacement.

PLAIN

Leaves the matching field unprocessed. Only available if the redaction target is a field (i.e., INRUPT_LOGGING_REDACTION_{NAME}_FIELD).

DROP

Suppresses the matching field. Only available if the redaction target is a field (i.e., INRUPT_LOGGING_REDACTION_{NAME}_FIELD).

PRIORITIZE

Changes the log level of the matching message.

SHA256

Replaces the matching text with its hash.

  • If the action is REPLACE ( default ), see also INRUPT_LOGGING_REDACTION_{NAME}_REPLACEMENT.

  • If the action is to PRIORITIZE, see also INRUPT_LOGGING_REDACTION_{NAME}_LEVEL .

For more information on log redaction, see Logging Redaction.

INRUPT_LOGGING_REDACTION_NAME_ENABLED

Default : true

A boolean that determines whether the redaction configurations with the specified INRUPT_LOGGING_REDACTION_{NAME}_ prefix is enabled.

For more information on log redaction, see Logging Redaction.

INRUPT_LOGGING_REDACTION_NAME_EXCEPTION

Fully qualified name of the exception class to match in the log messages (includes inner exception). Configure to target an exception message class.

For more information on log redaction, see Logging Redaction.

INRUPT_LOGGING_REDACTION_NAME_FIELD

Exact name of the field to match in the log messages. Configure to target a specific log message field for redaction.

For more information on log redaction, see Logging Redaction.

INRUPT_LOGGING_REDACTION_NAME_LEVEL

A new log level to use for the log message if the INRUPT_LOGGING_REDACTION_{NAME}_ACTION is PRIORITIZE .

INRUPT_LOGGING_REDACTION_NAME_PATTERN

A regex (see Java regex pattern ) to match in the log messages. Configure to target log message text that matches a specified pattern.

For more information on log redaction, see Logging Redaction.

INRUPT_LOGGING_REDACTION_NAME_REPLACEMENT

Replacement text to use if the INRUPT_LOGGING_REDACTION_{NAME}_ACTION is REPLACE .

If unspecified, defaults to [REDACTED] .

For more information on log redaction, see Logging Redaction.

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW

A comma-separated list audit events (unless specified in the corresponding INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY ).

This configuration is case-sensitive to the propagated properties in the baggage.

Tip To include a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY

A comma-separated list of application-defined properties to exclude from the associated audit messages. This setting takes precedence over INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW .

This configuration is case-sensitive to the propagated properties in the baggage.

Tip To exclude a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

INRUPT_LOGGING_REQUEST_METADATA_ALLOW

A comma-separated list of application-defined properties that can be included in the associated log messages (unless specified in the corresponding INRUPT_LOGGING_REQUEST_METADATA_DENY ).

Tip To include a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

INRUPT_LOGGING_REQUEST_METADATA_DENY

A comma-separated list. This setting takes precedence over INRUPT_LOGGING_REQUEST_METADATA_ALLOW.

A comma-separated list of non-baggage request headers to add to the baggage (unless specified in the corresponding INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY ); i.e., include these non-baggage request headers as application-defined properties.

The configuration is case-insensitive; i.e., the listed headers do not need to match the case of the client request headers. For example, a list that includes x-correlation-id can match x-correlation-id header, X-CoRrElAtIoN-Id header, etc.

See:

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY

A comma-separated list of non-baggage request headers to exclude from being added to the baggage ; i.e., excludes these headers as application-defined properties. This setting takes precedence over INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW .

The configuration is case-insensitive; i.e., the listed headers do not need to match the case of the client request headers. For example, a list that includes x-correlation-id can match (and exclude) x-correlation-id header, X-CoRrElAtIoN-Id header, etc.

See:

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_OVERRIDES

A flag that determines ESS behavior when metadata property is defined both as a header and as a baggage entry:
