Subject [jira] [Commented] (SOLR-8396) Investigate PointField to replace NumericField types
Date Fri, 25 Mar 2016 22:51:25 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15212537#comment-15212537

Shawn Heisey commented on SOLR-8396:
------------------------------------

bq. For users upgrading from versions < 6.0, there will be issues regardless.

There has to be a limit to the upgrade scenarios we are willing to support.

For users upgrading from 6.x with configs that they originally built for a previous major
release, whether their index is fully upgraded or not, problems are to be expected.  If we
have to worry about supporting ancient configurations, forward progress becomes difficult.

Another idea: Maybe the policy for deprecations in critical low-level components like Field
classes needs to be different than the general case -- kept around for two major releases
rather than one.  I'm not sure the Lucene guys would like that, because for that deprecation
policy in Solr to be effective, it would need to extend to any Lucene components that the
deprecated Solr Field classes depend on.  For a development library, that's a very oppressive
requirement.

> In LUCENE-6917, [~mikemccand] mentioned that DimensionalValues are better than NumericFields
in most respects. We should explore the benefits of using it in Solr and hence, if appropriate,
switch over to using them.
