Hi Subash, usually by default there is no problem in rolling back to the previous version. For instance if you are running 4.9 and you upgrade to 4.10 your bookies you can downgrade to 4.9 just by using the old code. This is because we introduce new features but they are disabled by default at least for one release.
But I suggest you to perform a test about the rollback before going to production Enrico Il giorno gio 16 apr 2020 alle ore 12:23 Subash K <[email protected]> ha scritto: > Hi, > > > > We are planning to introduce Apache Pulsar in our product.
