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)
