Crated project that tests *akka-persistence * to *pekko-persistence. *Here is the project pekko-persistence-test <https://github.com/Seetaramayya/pekko-persistence-test> that tests persistence with LevelDB and PostgresSQL JDBC plugins.
I could not find *"pekko-persistence-jdbc" *dependency in the snapshot repository so I published locally (it needs to be fixed once it is published) There are no surprises, everything is working fine. I did not test with MultiJVM tests (I don't think it is required because if something goes wrong there then it is much more bigger problem because nothing works in akka cluster as far as I know) On Sat, Feb 18, 2023 at 3:50 PM seetaramayya vadali <[email protected]> wrote: > Sure I’ll add standalone scenario. > > On Sat, 18 Feb 2023 at 15:01, Matthew Benedict de Detrich > <[email protected]> wrote: > >> > My worry is around lines like >> >> https://github.com/apache/incubator-pekko/blob/864ee821b99799a08392c2f3c143b40cecfda6c1/persistence/src/main/protobuf/MessageFormats.proto#L16 >> where the Pekko specific package name appears. >> >> So I did some primitive research on this when I did the package rename in >> pekko some time back and from what I gathered it should be a non issue >> because the java_package is not something that is sent over the wire, it's >> only used when generating the source files for the client. >> >> Would be great if someone can confirm/deny this. >> >> On Sat, Feb 18, 2023 at 2:58 PM PJ Fanning <[email protected]> wrote: >> >> > Thanks Seeta. >> > >> > If you have time to write a standalone scenario, that would be great. >> > Maybe a Github project that imports akka-persistence and >> > pekko-persistence.
