In addition to family 'name' and 'maxVersions' attributes,
individual table families can ve defined with several other
attributes such as
compression="$$$" - the compression option to use in HBase.
blockCache="$$$" - an LRU cache that contains three levels of block priority
to allow for scan-resistance and in-memory ColumnFamilies.
blockSize="$$$" - The blocksize can be configured for each ColumnFamily in
a table, and this defaults to 64k.
bloomFilter="$$$" - Bloom Filters can be enabled per-ColumnFamily.
maxVersions="$$$" - The maximum number of row versions to store is configured
per column family via HColumnDescriptor.
timeToLive="$$$" - ColumnFamilies can set a TTL length in seconds, and HBase
will automatically delete rows once the expiration time is
inMemory="$$$" - ColumnFamilies can optionally be defined as in-memory.
You should consult the current Gora gora-hbase documentation
for further information on properties and mapping configurtion.
