 extends <a href="../../../../../org/apache/hadoop/hbase/client/Query.html" title="class in org.apache.hadoop.hbase.client">Query</a></pre>
 <div class="block">Used to perform Scan operations.
  <p>
  All operations are identical to <a href="../../../../../org/apache/hadoop/hbase/client/Get.html" title="class in org.apache.hadoop.hbase.client"><code>Get</code></a> with the exception of instantiation. Rather than
  specifying a single row, an optional startRow and stopRow may be defined. If rows are not
  specified, the Scanner will iterate over all rows.
  <p>
  To get all columns from all rows of a Table, create an instance with no constraints; use the
  <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#Scan--"><code>Scan()</code></a> constructor. To constrain the scan to specific column families, call
  <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#addFamily-byte:A-"><code>addFamily</code></a> for each family to retrieve on your Scan instance.
  <p>
  To get specific columns, call <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#addColumn-byte:A-byte:A-"><code>addColumn</code></a> for each column to
  retrieve.
  <p>
  To only retrieve columns within a specific range of version timestamps, call
  <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setTimeRange-long-long-"><code>setTimeRange</code></a>.
  <p>
  To only retrieve columns with a specific timestamp, call <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setTimestamp-long-"><code>setTimestamp</code></a>
  .
  <p>
  To limit the number of versions of each column to be returned, call <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#readVersions-int-"><code>readVersions(int)</code></a>.
  <p>
  To limit the maximum number of values returned for each call to next(), call
  <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setBatch-int-"><code>setBatch</code></a>.
  <p>
  To add a filter, call <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setFilter-org.apache.hadoop.hbase.filter.Filter-"><code>setFilter</code></a>.
  <p>
  For small scan, it is deprecated in 2.0.0. Now we have a <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setLimit-int-"><code>setLimit(int)</code></a> method in Scan
  object which is used to tell RS how many rows we want. If the rows return reaches the limit, the
  RS will close the RegionScanner automatically. And we will also fetch data when openScanner in
  the new implementation, this means we can also finish a scan operation in one rpc call. And we
  have also introduced a <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setReadType-org.apache.hadoop.hbase.client.Scan.ReadType-"><code>setReadType(ReadType)</code></a> method. You can use this method to tell RS
  to use pread explicitly.
  <p>
  Expert: To explicitly disable server-side block caching for this scan, execute
  <a href="../../../../../org/apache/hadoop/hbase/client/Scan.html#setCacheBlocks-boolean-"><code>setCacheBlocks(boolean)</code></a>.
  <p>
  <em>Note:</em> Usage alters Scan instances. Internally, attributes are updated as the Scan runs
  and if enabled, metrics accumulate in the Scan instance. Be aware this is the case when you go to
  clone a Scan instance or if you go to reuse a created Scan instance; safer is create a Scan
  instance per usage.</div>

  SingleColumnValueFilter w/filterIfMissing == true, this can deliver huge perf gains when
  there's a cf with lots of data; however, it can also lead to some inconsistent results, as
  follows: - if someone does a concurrent update to both column families in question you may get
  a row that never existed, e.g. for { rowKey = 5, { cat_videos =&gt; 1 }, { video =&gt; "my cat"
  } } someone puts rowKey 5 with { cat_videos =&gt; 0 }, { video =&gt; "my dog" }, concurrent
  scan filtering on "cat_videos == 1" can get { rowKey = 5, { cat_videos =&gt; 1 }, { video =&gt;
