Subject [jira] [Commented] (SOLR-5302) Analytics Component
Date Thu, 21 Nov 2013 14:25:37 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13828972#comment-13828972

David Smiley commented on SOLR-5302:
------------------------------------

Fear not Nim (and others), Solr almost *never* changes the request/response params/format.
 It may have happened before but it is so rare that I simply can't recall the last time it
has.  Stuff gets deprecated but sticks around forever.  Backwards compatibility is kept to
extremely high standards here (good for you, sucks for us committers).  Instead of removal,
I suspect at some point in the future, the Stats' implementation would get replaced by a proxy
implementation that uses the new code in this Analytics component.  And that is not an option
until this Analytics component does everything Stats does (e.g. distributed-mode).

> This ticket is to track a "replacement" for the StatsComponent. The AnalyticsComponent
supports the following features:
> * All functionality of StatsComponent (SOLR-4499)
> * Field Faceting (SOLR-3435)
> ** Support for limit
> ** Sorting (bucket name or any stat in the bucket
> ** Support for offset
> * Range Faceting
> ** Supports all options of standard range faceting
> * Query Faceting (SOLR-2925)
> * Ability to use overall/field facet statistics as input to range/query faceting (ie
calc min/max date and then facet over that range
> * Support for more complex aggregate/mapping operations (SOLR-1622)
> ** Aggregations: min, max, sum, sum-of-square, count, missing, stddev, mean, median,
percentiles
> ** Operations: negation, abs, add, multiply, divide, power, log, date math, string reversal,
string concat
> ** Easily pluggable framework to add additional operations
> * New / cleaner output format
> Outstanding Issues:
> * Multi-value field support for stats (supported for faceting)
> * Multi-shard support (may not be possible for some operations, eg median)
