James Taylor commented on PHOENIX-934:
--------------------------------------
Global indexes are what we have today for secondary indexes: the secondary
index table is a separate, completely independent HBase table as described
here: http://phoenix.incubator.apache.org/secondary_indexing.html
Local indexes are where the index data and table data are co-resident for the
same region's worth of data as described here:
https://github.com/Huawei-Hadoop/hindex
They both have their pluses and minus. Local indexes are less expensive to
maintain because you don't have to make a cross region server call when you the
data changes. On the flip side, querying them may be more expensive as you have
to look in every region for the index data.
This JIRA is part of a larger issue to support these new kinds of indexes.
