James Taylor commented on PHOENIX-1561:
---------------------------------------
FWIW, secondary indexes and our skip scan will be used to service the Pig
LoadFunc if it's more efficient to do so. I'm curious about your HBaseStorage
implementation - what kind of optimizations will it do?

> URL: https://issues.apache.org/jira/browse/PHOENIX-1561
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.2
> Reporter: Brian Johnson
> Assignee: Brian Johnson
> Attachments: patch
>
>
> PhoenixHBaseLoader should implement both OrderedLoadFunc and
> CollectableLoadFunc just like HBaseStorage. There is nothing special that
> needs to be done other than implementing a single method. As in HBaseStorage,
> it is up to the user to ensure that the required constraints are not
> violated.

> public void ensureAllKeyInstancesInSameSplit() throws IOException {
> /**
> * no-op because hbase keys are unique
> * This will also work with things like
> DelimitedKeyPrefixRegionSplitPolicy
> * if you need a partial key match to be included in the split
> */
> LOG.debug("ensureAllKeyInstancesInSameSplit");
