--------------------------------------
Hi [~joel.bernstein]
I'm trying to understand why we need the {{cache}} array in {{SortQueue}} .
In reset could we simply do this?
{code:java}
protected void reset() {
Object[] heap = getHeapArray();
for (int i=1; i< heap.length; i++) {
heap[i] = proto.copy();
}
size = maxSize;
}{code}
> Reuse Lucene's PriorityQueue for the ExportHandler

> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Varun Thacker
> Assignee: Varun Thacker
> Priority: Major
>
> We have a priority queue in Lucene {{org.apache.lucene.utilPriorityQueue}} .
> The Export Handler also implements a PriorityQueue
> {{org.apache.solr.handler.export.PriorityQueue}} . Both are obviously very
> similar with minor API differences.
>
> The aim here is to reuse Lucene's PQ and remove the Solr implementation.
