+
+<p>Here you can see that we require the definition of two child elements
within the
+<code>gora-orm</code> mapping configuration, namely;</p>
+<p>The table element; where we specify: </p>
+<ol>
+<li>
+<p>a parameter relating to the HBase table name (String) e.g.
name=<b>"Employee"</b>, </p>
+</li>
+<li>
+<p>a nested element containing the type and definition of families we wish to
create within HBase. In this case we create one family <b>info</b> which could
have a combination of any of the following parameters;</p>
+<p><b>name</b> (String): family name e.g. info</p>
+<p><b>compression</b> (String): the compression option to use in HBase. Please
see <a href="http://hbase.apache.org/book/compression.html";>HBase
documentation</a>.</p>
+<p><b>blockCache</b> (boolean): an LRU cache that contains three levels of
block priority to allow for scan-resistance and in-memory ColumnFamilies.
Please see <a
href="https://hbase.apache.org/book/regionserver.arch.html#block.cache";>HBase
documentation</a>.</p>
+<p><b>blockSize</b> (Integer): The blocksize can be configured for each
ColumnFamily in a table, and this defaults to 64k. Larger cell values require
larger blocksizes. There is an inverse relationship between blocksize and the
resulting StoreFile indexes (i.e., if the blocksize is doubled then the
resulting indexes should be roughly halved). Please see <a
href="http://hbase.apache.org/book/perf.schema.html#schema.cf.blocksize";>HBase
documentation</a>. </p>
+<p><b>bloomFilter</b> (String): Bloom Filters can be enabled per-ColumnFamily.
We use <code>HColumnDescriptor.setBloomFilterType(NONE | ROW | ROWCOL)</code>
to enable blooms per Column Family. Default = NONE for no bloom filters. If
ROW, the hash of the row will be added to the bloom on each insert. If ROWCOL,
the hash of the row + column family name + column family qualifier will be
added to the bloom on each key insert. Please see <a
href="http://hbase.apache.org/book/perf.schema.html#schema.bloom";>HBase
documentation</a>.</p>
+<p><b>maxVersions</b> (Integer): The maximum number of row versions to store
is configured per column family via <code>HColumnDescriptor</code>. The default
for max versions is <b>3</b>. This is an important parameter because HBase does
not overwrite row values, but rather stores different values per row by time
(and qualifier). Excess versions are removed during major compaction's. The
number of max versions may need to be increased or decreased depending on
application needs. Please see <a
href="http://hbase.apache.org/book/schema.versions.html";>HBase
documentation</a>.</p>
+<p><b>timeToLive</b> (Integer): ColumnFamilies can set a TTL length in
seconds, and HBase will automatically delete rows once the expiration time is
reached. This applies to all versions of a row - even the current one. The TTL
time encoded in the HBase for the row is specified in UTC. Please see <a
href="https://hbase.apache.org/book/ttl.html";>HBase documentation</a>.</p>
+<p><b>inMemory</b> (Boolean): ColumnFamilies can optionally be defined as
in-memory. Data is still persisted to disk, just like any other ColumnFamily.
In-memory blocks have the highest priority in the Block Cache, but it is not a
guarantee that the entire table will be in memory. Please see <a
href="http://hbase.apache.org/book/perf.schema.html#cf.in.memory";>HBase
documentation</a>.</p>
+</li>
+</ol>
+<p>The class element where we specify of persistent fields which values should
map to. This contains;</p>
+<ol>
+<li>
+<p>a parameter containing the Persistent class name e.g.
<b>org.apache.gora.examples.generated.Employee</b>, </p>
+</li>
+<li>
+<p>a parameter containing the keyClass e.g. <b>java.lang.String</b> which
specifies the keys which map to the field values, </p>
+</li>
+<li>
+<p>a parameter containing the Table name e.g. <b>Employee</b> which matches to
the above Table definition,</p>
+</li>
+<li>
+<p>finally nested child element(s) mapping fields which are to be persisted
into HBase. These fields need to be configured such that they receive;</p>
+<p>a parameter containing the <b>name</b> e.g. (name, dateOfBirth, ssn and
salary respectively), </p>
+<p>a parameter containing the column <b>family</b> to which they belong e.g.
(all info in this case), </p>
+<p>an optional parameter <b>qualifier</b>, which enables more granular control
over the data to be persisted into HBase.</p>
