On a few occasions, I have to check if a key exists in a table or not. What's the best way to do it? The htable interface doesn't have any function to check if a key exists or not, and I have to specify at least one column when fetching a key.
At the moment I have secondary tables (with bloomfilters and blockcache enabled) just used to check if a key exists. When adding deleting a key, I will also add/delete an entry in the secondary table Another possibility would be to just have an nearempty columnfamily used to test if a key exists (my other column families always have about 100 KB of data in it, and I don't want hbase to fetch that data from disk).
