Class SolrRepresentationIndexer

java.lang.Object

eu.europeana.cloud.service.mcs.persistent.SolrRepresentationIndexer

@Component
public class SolrRepresentationIndexer
extends Object

Receives information about modifications in record representations and their data set assignments and sends them to index. Uses asynchronous queue to communicate with Data Lookup Service which is responsible for Solr index updates.

Method Detail

insertRepresentation

public void insertRepresentation(eu.europeana.cloud.common.model.Representation representation,
                        int partitionKey)

Indexes representation version (new or updated). If inserted representation version is persistent, there there might be some data set assignment changes involved (in cases where representation in latest persistent version is assigned to data set) - in this case, such reassignment is also done.

Parameters:

representation - representation version.

partitionKey - using to route message to different partitions.

removeRepresentationVersion

public void removeRepresentationVersion(String versionId,
                               int partitionKey)

Removes representation version from index. This method should be invoked only for temporary representation versions (although no verification is made in this method) - because no dataset reassignment is performed. *

Parameters:

versionId - representation version id

partitionKey - using to route message to different partitions.

removeRepresentation

public void removeRepresentation(String cloudId,
                        String representationName,
                        int partitionKey)

Removes all representation's versions from index.

Parameters:

cloudId - record id

representationName - representation's schema

partitionKey - using to route message to different partitions.

removeRecordRepresentations

public void removeRecordRepresentations(String cloudId,
                               int partitionKey)

Removes all record's representations with all their versions from index.

Parameters:

cloudId - record id

partitionKey - using to route message to different partitions.

removeAssignment

public void removeAssignment(String cloudId,
                    String representationName,
                    eu.europeana.cloud.common.model.CompoundDataSetId dataSetId,
                    int partitionKey)

Removes assignment between data set and representation (regardless its version).

Parameters:

cloudId - record id

representationName - representation's schema

dataSetId - dataset id with owner's (provider's) id.

partitionKey - using to route message to different partitions.

addAssignment

public void addAssignment(String versionId,
                 eu.europeana.cloud.common.model.CompoundDataSetId dataSetId,
                 int partitionKey)

Adds assignment between data set and a representation version.

Parameters:

versionId - representation version id.

dataSetId - dataset id with owner's (provider's) id.

partitionKey - using to route message to different partitions.

removeAssignmentsFromDataSet

public void removeAssignmentsFromDataSet(eu.europeana.cloud.common.model.CompoundDataSetId compoundDataSetId,
                                int partitionKey)

Removes data set assignments from ALL representation. This method is to be used if whole data set is removed.

Parameters:

compoundDataSetId - dataset id with owner's (provider's) id.

partitionKey - using to route message to different partitions.
