[jira] [Comment Edited] (LUCENE-6917) Move NumericField out of core
to backwards-codecs
[ https://issues.apache.org/jira/browse/LUCENE-6917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15045451#comment-15045451 ]

bq. Because this is the simplest cutover I could do for now. For BBoxStrategy, it would be a major change (you must reindex) to switch from postings to DimensionalValues
Since this is for 6.0, a major release, so this is acceptable.
bq. I think we should switch over consumers of LegacyNumeric* in follow-on issues?
Okay, if that's how you want to do it. But I figured the effort (albeit not "large") in using LegacyNumeric could have instead been directed on using DimensionalValues, and in the end there will be less effort to move fully over. For example adding dependency on backwards-codecs only to then take it away in another issue. Your call. Maybe I'm misjudging what's involved in switching to DimensionalValues but I hope it's easy.

> DimensionalValues seems to be better across the board (indexing time, indexing size, search-speed, search-time heap required) than NumericField, at least in my testing so far.
> I think for 6.0 we should move {{IntField}}, {{LongField}}, {{FloatField}}, {{DoubleField}} and {{NumericRangeQuery}} to {{backward-codecs}}, and rename with {{Legacy}} prefix?
