+Also, we do not store the comparator in the version 2 file info anymore.
Instead, we store it in the fixed file trailer.
This is because we need to know the comparator at the time of parsing the load-on-open section of the HFile.

== Constraints
HBase currently supports 'constraints' in traditional (SQL) database parlance.
-The advised usage for Constraints is in enforcing business rules for attributes in the table (e.g. make sure values are in the range 1-10). Constraints could also be used to enforce referential integrity, but this is strongly discouraged as it will dramatically decrease the write throughput of the tables where integrity checking is enabled.
-Extensive documentation on using Constraints can be found at: link:http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/constraint[Constraint] since version 0.94.
