Erick Erickson commented on SOLR-5302:
--------------------------------------
OK, I'm not quite sure how to proceed given the size of this patch. What do
people think about this as a way forward?
I'll do all the pre-commit/ant testing stuff, basically the secretarial work
involved in committing this to trunk. Since this is a new component, it's at
least somewhat isolated from other bits of the code. I'll let it bake for a
while in trunk and then merge into 4x. Since we just put 4.5.1 out (well, Mark
did), if sometime a week or so after it's committed to trunk I merge it to 4x,
there'll be substantial time to bake there before any 4.6 goes out.
Of course I'll look it over, but given the size it'll be mostly a surface level
look-over. Anyone who wants to delve into details is more than welcome to...
How does that sound?

> 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)

> ** 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)
