addToCurrentBulkRequestAsUpsert

public void addToCurrentBulkRequestAsUpsert(CommandContext commandContext,
                                            com.fasterxml.jackson.databind.node.ObjectNode data,
                                            String idFieldName)

Description copied from interface: LowLevelIndexingService

Adds the ObjectNode data as an upsert (i.e. merge if exist, insert if not) to the current bulk request (or creates a bulk request if needed). The bulk request is executed at the end of the transactions, when all items for indexing have been added.

Specified by:

addToCurrentBulkRequestAsUpsert in interface LowLevelIndexingService

addToCurrentBulkRequestAsFullIndex

public void addToCurrentBulkRequestAsFullIndex(CommandContext commandContext,
                                               String type,
                                               String id,

                                               String idFieldName)

Description copied from interface: LowLevelIndexingService

Adds the ObjectNode data as a full index (i.e. replace the current indexed document if any exists) to the current bulk request (or creates a bulk request if needed). The bulk request is executed at the end of the transactions, when all items for indexing have been added. The {type, id} parameters are not used during indexing, but is registered internally and can be used to check whether indexing was already triggered via the LowLevelIndexingService.isFullIndexRegisteredOnCurrentBulkRequest(CommandContext, String, String) method. This allows to avoid costly recalculation of data or doing the same indexing operation multiple times in ES. Note that this method doesn't apply that check automatically, and the caller is responsible for calling it.

Specified by:

addToCurrentBulkRequestAsFullIndex in interface LowLevelIndexingService

addToCurrentBulkRequestAsFullIndexWithExternalVersion

public void addToCurrentBulkRequestAsFullIndexWithExternalVersion(CommandContext commandContext,
                                                                  String type,
                                                                  String id,
                                                                  com.fasterxml.jackson.databind.node.ObjectNode data,

Description copied from interface: LowLevelIndexingService

Specified by:

addToCurrentBulkRequestAsFullIndexWithExternalVersion in interface LowLevelIndexingService

addToCurrentBulkRequestAsUpsertWithScript
