Establish Solr TLP
The git repo is split, gradle build adapted, release process separated etc. See Solr TLP needed changes for all related tasks.
The 9.0 release will be the first release after the TLP split.
Lucene will first release v9.0.0 without Solr, and then Solr can independently release Solr 9.0 with Lucene 9.0 when Solr is ready for it.
Solr 9.0
Early 2021. First release as TLP. The theme of this release is to use Lucene 9.0 and to introduce some major frameworks.
We should not remove all features/APIs deprecated in 8.x yet, to give users a path to upgrade to 9.x without all the extra noise. Deprecated features can be removed in a later 9.x release, when the new alternative is solid and well known.
| Item | Description | Contributors | Theme | Jira |
|---|---|---|---|---|
| First party packages & Slim Solr distribution | Solr should have first party packages, and a slim Solr tarball that doesn't have the first party packages | Ishan, Noble, Jan, et. al. | Lean Solr Core | |
| V2 API to be the default | Ref guide docs should use V2, where necessary we build V2 APIs, switch SolrJ to use V2 APIs, etc. | Usability | ||
| Autoscaling / Replica assignment V2 | A new pluggable framework replaces current autoscaling | Andrzej, Ilan, Noble | Lean Solr Core | |
| HDFS moved away from Solr-Core | Build a first party package out of HDFS support | Istvan Farkas, Gezapeti | Lean Solr Core | |
| Remove Ant support | This is partly done | Tech-debt | ||
| Index Lifecycle Management | Automatically move indices between hot, warm and cold phases | Atri Sharma | Feature | |
| POJOs instead of loosely typed objects | Start using POJOs/interfaces wherever possible in public APIs where ever possible | Noble Paul | ||
| Remove Filter.java from Solr | Filter.java is a legacy relic from earlier Lucene days. Solr uses Filter in a variety of places where it can use other constructs or in some cases we need to make new constructs. In some cases like TwoPhaseIterator, this is an optimization. | David Smiley | Tech-debt |

Solr 9.1
Soon after 9.0. The main theme of this release is to solidify all the new frameworks.
This release may still depend on Lucene 9.0 if we wish.
