GitHub user ptrdom edited a comment on the discussion: Artifical back pressure on JDBC projections
@rsmidt Maybe `sourceProvider` could be wrapped to add [throttling](https://pekko.apache.org/docs/pekko/current/stream/operators/Source-or-Flow/throttle.html) to the source? ```scala JdbcProjection.atLeastOnce( ProjectionId.of(PROJECTION_NAME, tag), new SourceProvider[Offset, Envelope] { val wrapped = sourceProvider override def source(offset: () => Future[Option[Long]]): Future[Source[Envelope, NotUsed]] = wrapped.source(offset).map(_.throttle(1, 1.second)) override def extractOffset(envelope: Envelope): Long = wrapped.extractOffset(envelope) override def extractCreationTime(envelope: Envelope): Long = wrapped.extractOffset(envelope) }, ... ) ``` GitHub link: https://github.com/apache/pekko/discussions/2431#discussioncomment-14893907 ---- This is an automatically sent email for [email protected].
