HBase doesn't support indexing of other columns in the table (also known as
secondary indexes
).
However, there are several strategies for supporting the types of query that secondary indexes provide, each
with different trade-offs between storage space, processing load, and query execution time; see the
HBase Re-
ference Guide
for a discussion.
