To address your concern Bernd, The goal of this deprecation is not to remove the functionality entirely. The primary purpose is to remove the code from Solr Core. Before removing a feature we aim to either:
- Move the code to another repository, and have it be loadable via a plugin - Replace the feature with something more stable and/or scalable. (Likely loadable via a plugin or run in a separate application) I understand your frustration, but the ultimate goal here is to make Solr more customizable and plugable (and therefore learner by default). This way the base Solr functionality can be as bug-free and performant as possible, and any extra features can be added on top as needed. We would appreciate feedback for how the community would prefer these features be provided in the future, so that we make the transition smoother and the end product better. - Houston On Wed, Jul 15, 2020 at 5:51 PM Ishan Chattopadhyaya < ichattopadhy...@gmail.com> wrote: > On Wed, 15 Jul, 2020, 8:37 pm Bernd Fehling, < > bernd.fehl...@uni-bielefeld.de> > wrote: > > > > > > > Am 15.07.20 um 16:07 schrieb Ishan Chattopadhyaya: > > > Dear Solr Users, > > > > > > In this release (Solr 8.6), we have deprecated the following: > > > > > > 1.
