Hi Hbase users, We have a use case where we need to know how data looked at a given time in past.
The data is stored in HBase of course, with multiple versions. And, the goal is to be able to extractall records (rowkey, columns) as of a given timestamp, to a file. I am trying to figure out the best way to achieve this. The options I know are: 1. Write a *Java* client using HBase Java API, and scan the hbase table. 2. Do the same, but over *Thrift* HBase API using Perl (since our environment is mostly Perl). 3. Use *Hive *to point to HBase table, and use Sqoop to extract data from the Hive table and onto client / RDBMS. 4. Use *Pig *to extract data from HBase table and dump it on HDFS and move the file over to the client. So far, I have successfully implemented option (2). I am still running some tests to see how it performs, but it works fine as such. My questions are: 1. Is option (3) or (4) even possible? I am not sure if we can access the table for a given timestamp over Pig or Hive. 2. Is there any other better way of achieving this? Thanks! Gaurav
