Hi all, We are planning to change versions of all of our tables (3 tables with 3 to 4 column families each) from 3 (default) to 1. Here is why we want to change it: 1) We have never used versions and we don't really need them 2) It should reduce amount of data Hbase loads in memory (StoreFiles or Stores) by 2/3rd.
Here are my questions: 1) Is this correct? Will it really reduce the amount of data it loads in memory? 2) How do I do this in production? I know that HBase shell supports alter statement. Do you recommend using that? If I execute an alter statement, will it immediately start lot of activity there by degrading our real time performance? 3) Do we need to do anything else before or after we run alter command? Regards, Vaibhav
