SOLR-8996: Greatly decreases the probability of a RandomStream test failure
from 1 in 5! to 1 in 1000!
> Add Random Streaming Expression
> -------------------------------
>
> Key: SOLR-8996
> URL: https://issues.apache.org/jira/browse/SOLR-8996
> Project: Solr
> Issue Type: New Feature
> Reporter: Joel Bernstein
> Assignee: Dennis Gove
> Fix For: 6.1
>
> Attachments: RandomStream.java,
> SOLR-8996-decrease-failure-probability.patch, SOLR-8996.patch
>
>
> The random Streaming Expression will return a *limited* random stream of
> Tuples that match a query. This will be useful in many different scenarios
> where random data sets are needed.
> Proposed syntax:
> {code}
> random(baskets, q="productID:productX", rows="100", fl="basketID")
> {code}
> The sample code above will query the *baskets* collection and return 100
> random *basketID's* where the productID is productX.
> The underlying implementation will rely on Solr's random field type.
