Method Detail

buildScriptApplier

protected java.util.function.BiFunction<org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?>,ScrollableHitSource.Hit,org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?>> buildScriptApplier()

Build the BiFunction to apply to all RequestWrapper.

buildBulk

protected org.elasticsearch.action.bulk.BulkRequest buildBulk(java.lang.Iterable<? extends ScrollableHitSource.Hit> docs)

Specified by:

buildBulk in class AbstractAsyncBulkByScrollAction<Request extends AbstractBulkByScrollRequest<Request>>

accept

protected boolean accept(ScrollableHitSource.Hit doc)

Used to accept or ignore a search hit. Ignored search hits will be excluded from the bulk request. It is also where we fail on invalid search hits, like when the document has no source but it's required.

buildRequest

protected abstract org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?> buildRequest(ScrollableHitSource.Hit doc)

Build the RequestWrapper for a single search hit. This shouldn't handle metadata or scripting. That will be handled by copyMetadata and apply functions that can be overridden.

copyMetadata

protected org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?> copyMetadata(org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?> request,
                                                                                                              ScrollableHitSource.Hit doc)

Copies the metadata from a hit to the request.

copyRouting

protected void copyRouting(org.elasticsearch.index.reindex.AbstractAsyncBulkIndexByScrollAction.RequestWrapper<?> request,
                           java.lang.String routing)

Copy the routing from a search hit to the request.
