Does Solr mark any versions for Long Term Support (LTS) like other
technology? I have not seen this, but wanted to check.
I am not really sure whether this is fully documented anywhere, but I
can tell you how we manage support.
The current major version (currently 9.x) is fully supported. Most
bugfixes and new features will only be available in the next minor
release after the change has been committed to the codebase.
The previous major version (currently 8.x) is in what we call
maintenance mode. Only showstopper bugs and security issues will be
fixed in that version. Occasionally there may be new point releases for
these kinds of problems in previous minor versions within the current
major version.
All major releases older than the previous major version are unsupported.
Because releases are never planned in advance, we can't offer specific
timelines like X years of support for a specific version.
I realize that SolrCloud is the recommended approach. Are there any
concerns of Solr user-managed-mode being deprecated in 1 year, 3 years, 5
years or 10 years?
This has been discussed a little bit, with no decisions made.
Standalone mode is NOT deprecated, but if that does happen, there is no
way to predict what kind of timeframe there might be before complete
removal. Removal of any major feature does not happen before the next
major version after the deprecation has been decided.
Major release timelines in the past:
6.0.0 announced on 2016/04/08
7.0.0 announced on 2017/09/20
8.0.0 announced on 2019/03/13
9.0.0 announced on 2022/05/12
Which means there isn't a lot of predictability to major releases. The
last one was 3 years, but the previous two were only about 1.5 years.
Thanks,
Shawn
