Slow save due to @IndexingDependency

Hibernate Search
1

Hello.
repository.save(objectA) is too slow due to @IndexingDependency(derivedFrom).
I watch that during save it does always select from the objectB. Removing them works fine.
How can i skip this problem ?

@Indexed(index = "idx_name")
@Table(name = "tableName")
public class ObjectΑ {
	
	@Id
	@Column(name = "id", nullable = false, precision = 18)
    @ScaledNumberField(decimalScale = 0, sortable = Sortable.YES)
	private BigInteger id;
	
	
	@OneToMany(mappedBy = "objectA", cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
	@IndexedEmbedded(structure = ObjectStructure.NESTED, includePaths = {""relObjectb.id", "fielda", "fieldb", ...})
	@IndexingDependency(reindexOnUpdate = ReindexOnUpdate.SHALLOW)
	private List<ObjectB> bList = new ArrayList<>();

    .
    .
    .

    @Transient
		@IndexingDependency(derivedFrom = @ObjectPath({
			@PropertyValue(propertyName = "bList"),
			@PropertyValue(propertyName = "debit")
	}))
	@ScaledNumberField(decimalScale = 2, sortable = Sortable.YES)
	private BigDecimal totalObjectBDebit;
	
	public BigDecimal getTotalObjectBDebit() {
		BigDecimal objectBDebit = BigDecimal.ZERO;
		if (CollectionUtils.isNotNullOrEmpty(bList)) {
			for (final ObjectΒ b: bList) {
				objectBDebit = objectBDebit .add(b.getDebit() != null ? b.getDebit() : BigDecimal.ZERO);
			}
		}
		
		return objectBDebit;
	}
	
	@Transient
		@IndexingDependency(derivedFrom = @ObjectPath({
			@PropertyValue(propertyName = "bList"),
			@PropertyValue(propertyName = "debit")
	}))
	@ScaledNumberField(decimalScale = 2, sortable = Sortable.YES)
	private BigDecimal totalObjectΒCredit;
	
	public BigDecimal getTotalObjectΒCredit() {
		BigDecimal objectΒCredit = BigDecimal.ZERO;
		if (CollectionUtils.isNotNullOrEmpty(bList)) {
			for (final ObjectΒ b: bList) {
				objectΒCredit = objectΒCredit .add(b.getCredit() != null ? b.getCredit() : BigDecimal.ZERO);
			}
		}
		
		return objectΒCredit ;
	}
	
	@Transient
		@IndexingDependency(derivedFrom = @ObjectPath({
			@PropertyValue(propertyName = "bList"),
			@PropertyValue(propertyName = "totalamount")
	}))
	@ScaledNumberField(decimalScale = 2, sortable = Sortable.YES)
	private BigDecimal totalObjectΒTotalamount;
	
	public BigDecimal getTotalObjectΒTotalamount() {
		BigDecimal objectΒTotalamount = BigDecimal.ZERO;
		if (CollectionUtils.isNotNullOrEmpty(bList)) {
			for (final ObjectΒ b: bList) {
				objectΒTotalamount = objectΒTotalamount .add(b.getTotalamount() != null ? b.getTotalamount() : BigDecimal.ZERO);
			}
		}
		
		return objectΒTotalamount ;
	}

}

ι expected these fields to affect the index only when the field in the 2nd propertyvalue is changed(debit, credit or totalamount), so to execute select * from objectB only in this case and not in every save of the objectA

I think this is related to the other question Avoiding Indexing on Unchanged Fields - #2 by mbekhta
if the save operation is slow, you could consider using the outbox-polling coordination strategy to do the reindexing work in the background.
