[jira] [Comment Edited] (SOLR-5302) Analytics Component
[ https://issues.apache.org/jira/browse/SOLR-5302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13816815#comment-13816815 ]

Yes my solr cloud is sharded, I split the index in two shards. I applied the patch to Solr 4.5.1 and tried to test the Analytics component with the standard solr example (exampledocs folder).
I have two shards (shard1, shard2) with 32 documets (exampledocs post.jar).
For example when I execute the following query in a single solr instance (no shards) it returns stats:
http://localhost:8983/solr/select?q=*:*&olap=true&olap.req1.statistic.stat1=sum(price)
Response:
<lst name="stats">
<lst name="req1">
<double name="stat1">5251.270030975342</double>
</lst>
</lst>
If I try to execute the same query in a solr cloud sharded (two shard) it return no stats result.
I see there are some methods in the AnalyticsComponent.class that are not implemented:
modifyRequest, handleResponses, finishStage
I think the not implemented methods is the reason of why the analytics component is not returning data in a shard enviorement.
Please I really need help on this.

> Project: Solr
> Issue Type: New Feature
> Reporter: Steven Bower

> 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)
