Like I said in my first email, we recommend 1GB. > Are there any > side-effects we may expect when we set this value to say 1 GiB? HBase may be faster overtime since less splitting occurs. Splitting is good because it basically shards the data, but you don't want that to happen too often past a certain point. Some people even prefer to pre-split their tables and then disable splitting since it's known to have a few deficiencies... but that's not optimal either. Recently I worked on HBASE-3308 to speed up one part of the splitting process. > I suppose at > least a bit longer random gets? I see no reason why it would do that. J-D
