[ANNOUNCE] Apache Solr 8.6.0 released
The Lucene PMC is pleased to announce the release of Apache Solr 8.6.0.
Solr is the popular, blazing fast, open source NoSQL search platform from
the Apache Lucene project. Its major features include powerful full-text
search, hit highlighting, faceted search, dynamic clustering, database
integration, rich document handling, and geospatial search. Solr is highly
scalable, providing fault tolerant distributed search and indexing, and
powers the search and navigation features of many of the world's largest
internet sites.
Solr 8.6.0 is available for immediate download at:
<https://lucene.apache.org/solr/downloads.html>
### Solr 8.6.0 Release Highlights:
* Cross-Collection Join Queries: Join queries can now work
cross-collection, even when shared or when spanning nodes.
* Search: Performance improvement for some types of queries when exact hit
count isn't needed by using BlockMax WAND algorithm.
* Streaming Expression: Percentiles and standard deviation aggregations
added to stats, facet and time series. Streaming expressions added to
/export handler. Drill Streaming Expression for efficient and accurate
high cardinality aggregation.
* Package manager: Support for cluster (CoreContainer) level plugins.
* Health Check: HealthCheckHandler can now require that all cores are
healthy before returning OK.
* Zookeeper read API: A read API at /api/cluster/zk/* to fetch raw ZK data
and view contents of a ZK directory.
* Admin UI: New panel with security info in admin UI's dashboard.
* Query DSL: Support for {param:ref} and {bool: {excludeTags:""}}
* Ref Guide: Major redesign of Solr's documentation.
Please read CHANGES.txt for a full list of new features and changes:
<https://lucene.apache.org/solr/8_6_0/changes/Changes.html>
Solr 8.6.0 also includes features, optimizations and bugfixes in the
corresponding Apache Lucene release:
<https://lucene.apache.org/core/8_6_0/changes/Changes.html>
Note: The Apache Software Foundation uses an extensive mirroring network for
distributing releases. It is possible that the mirror you are using may not
have
replicated the release yet. If that is the case, please try another mirror.
This also applies to Maven access.

matthew,
In the future too, it's still going to be
"curl solr:8983/collection/dataimport?blah"
It's just that, you will have to run 2 or 3 extra commands for once
before you run that curl command

I hear all of that and agree, obviously, but "curl
solr:8983/collection/dataimport?blah" in cron was *pretty freaking
easy* ;)
Not sure why "pull" is elevated to "anti-pattern"; data is data is data

Thanks Aroop for your feedback. We shall try to ensure continuity of

DIH is available as a community supported package. However, it is an
anti-pattern for a search engine to be pulling data from outside. Instead,
please consider writing separate indexing programs that pull data from the
database systems and index into Solr. It is not only a good practice, but
also more efficient in terms of throughput. For more information on this,
please start another thread in solr-users@ list, and more people can

Thanks Aroop for your feedback. We shall try to ensure continuity of
functionality via packages. Your help in those efforts would be greatly
appreciated as well. Let us take this discussion to SOLR-14660.
> Is there a replacement for DIH?
DIH is available as a community supported package. However, it is an
anti-pattern for a search engine to be pulling data from outside. Instead,
please consider writing separate indexing programs that pull data from the
database systems and index into Solr. It is not only a good practice, but
also more efficient in terms of throughput. For more information on this,
please start another thread in solr-users@ list, and more people can
suggest best alternatives here.

DIH is available as a community supported package. However, it is an
anti-pattern for a search engine to be pulling data from outside. Instead,
please consider writing separate indexing programs that pull data from the

Dear Solr Users,
In this release (Solr 8.6), we have deprecated the following:
1. Data Import Handler
2. HDFS support
3. Cross Data Center Replication (CDCR)
All of these are scheduled to be removed in a future 9.x release.
It was decided that these components did not meet the standards of quality
and support that we wish to ensure for all components we ship. Some of
these also relied on design patterns that we no longer recommend for use in
critical production environments.
If you rely on these features, you are encouraged to try out community
supported versions of these, where available [0]. Where such community
support is not available, we encourage you to participate in the migration
of these components into community supported packages and help continue the
development. We envision that using packages for these components via
package manager will actually make it easier for users to use such features.

Dear Solr Users,
In this release (Solr 8.6), we have deprecated the following:
1. Data Import Handler
2. HDFS support
3. Cross Data Center Replication (CDCR)
All of these are scheduled to be removed in a future 9.x release.
It was decided that these components did not meet the standards of quality
and support that we wish to ensure for all components we ship. Some of
these also relied on design patterns that we no longer recommend for use in
critical production environments.
If you rely on these features, you are encouraged to try out community
supported versions of these, where available [0]. Where such community
support is not available, we encourage you to participate in the migration
of these components into community supported packages and help continue the
development. We envision that using packages for these components via
package manager will actually make it easier for users to use such features.

Re: [ANNOUNCE] Apache Solr 8.6.0 released
Posted by Aroop Ganguly <ar...@apple.com.INVALID>.
Just to highlight the usage and importance of some of the items here.
1. HDFS Backup/Restore is integral to our system architecture, index distribution and Disaster Recovery (system used by 1000+ users internally)
2. HDFS Directory factory, Embedded Solr, these items too are very important for offline index generation at large scale (~5-10TB big source data)
We really use these items and they are very relevant for companies that run Solr to augment Big Data analysis.
I just wanted to mention this in case these features’ need and value to customers/users were not represented as yet.
I do support the cleansing of the core as long these items are still available via dedicated module/plug-ins.
Thanks for the discussion around this. I hope the PMC community will consider these things and guide accordingly.

Re: [ANNOUNCE] Apache Solr 8.6.0 released
Posted by Anshum Gupta <an...@anshumgupta.net>.
Thanks for the feedback, Colvin. We'll certainly try and do something
around making the deprecations more visible and easier to track for all
users. I'm not sure if 'news' is the right section, but I think it might be
good to have a section on the website for users to look at and get a better
idea about.
The PMC and committers are certainly aware of the importance of not
dropping desirable features but let's not hijack the release announcement
thread for this discussion.

Perhaps the deprecation notices should feature on
https://lucene.apache.org/solr/news.html ? Because right now, they're not *very

May we ask what in hdfs support is being deprecated? Is Hdfs backup and restore being deprecated ?

Re: [ANNOUNCE] Apache Solr 8.6.0 released
Posted by Houston Putman <ho...@gmail.com>.
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.
