Subject Bloom Filter based scanner/filter
Date Tue, 15 Jan 2013 20:24:54 GMT
I am building a data cube on top of HBase. All access to the data is by map/reduce jobs. I
want to build a scanner that matches based on the set intersection of bloom filters. First
I run a map/reduce job on table A. For every row I match in table A, I add the row key to
a bloom filter. I then to a map/reduce job on table B.
