+<div class="block">Computes approximate <a href="http://en.wikipedia.org/wiki/Quantile" target="_blank">quantiles</a>
+ for a (not necessarily sorted) input bag, using the Munro-Paterson algorithm.
+
+ <p>
+ The algorithm is described here:
+ <a href="http://www.cs.ucsb.edu/~suri/cs290/MunroPat.pdf" target="_blank">http://www.cs.ucsb.edu/~suri/cs290/MunroPat.pdf</a>
+ </p>
+
+ <p>
+ The implementation is based on the one in Sawzall, available here:
+ <a href="http://szl.googlecode.com/svn-history/r41/trunk/src/emitters/szlquantile.cc">szlquantile.cc</a>
+ </p>
+
+ <p>
+ N.B., all the data is pushed to a single reducer per key, so make sure some partitioning is
+ done (e.g., group by 'day') if the data is too large. That is, this isn't distributed quantiles.
+ </p>
+
+ <p>
+ Note that unlike datafu's standard Quantile algorithm, the Munro-Paterson algorithm gives
+ <b>approximate</b> quantiles and does not require the input bag to be sorted. Because it implements
+ accumulate, StreamingQuantile can be much more efficient than Quantile for large amounts of data which
+ do not fit in memory. Quantile must spill to disk when the input data is too large to fit in memory,
+ which will contribute to longer runtimes.
+ </p>
+
+ <p>The constructor takes a single integer argument that specifies the number of evenly-spaced
+ quantiles to compute, e.g.,</p>
+
+ <ul>
+ <li>StreamingQuantile('3') yields the min, the median, and the max
+ <li>StreamingQuantile('5') yields the min, the 25th, 50th, 75th percentiles, and the max
+ <li>StreamingQuantile('101') yields the min, the max, and all 99 percentiles.
+ </ul>
+
+ <p>Alternatively the constructor can take the explicit list of quantiles to compute, e.g.</p>
+
+ <ul>
+ <li>StreamingQuantile('0.0','0.5','1.0') yields the min, the median, and the max
+ <li>StreamingQuantile('0.0','0.25','0.5','0.75','1.0') yields the min, the 25th, 50th, 75th percentiles, and the max
+ </ul>
+
+ <p>The list of quantiles need not span the entire range from 0.0 to 1.0, nor do they need to be evenly spaced, e.g.</p>
+
+ <ul>
+ <li>StreamingQuantile('0.5','0.90','0.95','0.99') yields the median, the 90th, 95th, and the 99th percentiles
+ <li>StreamingQuantile('0.0013','0.0228','0.1587','0.5','0.8413','0.9772','0.9987') yields the 0.13th, 2.28th, 15.87th, 50th, 84.13th, 97.72nd, and 99.87th percentiles
+ </ul>
+
+ <p>Be aware when specifying the list of quantiles in this way that more quantiles may be computed internally than are actually returned.
+ The GCD of the quantiles is found and this determines the number of evenly spaced quantiles to compute. The requested quantiles
+ are then returned from this set. For instance:</p>
+
+ <ul>
+ <li>If the quantiles 0.2 and 0.6 are requested then the quantiles 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0 are computed
+ because 0.2 is the GCD of 0.2, 0.6, and 1.0.</li>
+ <li>If 0.2 and 0.7 are requested then the quantiles 0.0, 0.1, 0.2, ... , 0.9, 1.0 are computed because 0.1 is the
+ GCD of 0.2, 0.7, and 1.0.</li>
+ <li>If 0.999 is requested the quantiles 0.0, 0.001, 0.002, ... , 0.998, 0.999, 1.0 are computed because 0.001 is
+ the GCD of 0.999 and 1.0.</li>
+ </ul>
+
+ <p>The error on the approximation goes down as the number of buckets computed goes up.</p>
+
+ Example:
+ <pre>
+ <code>define Quantile datafu.pig.stats.StreamingQuantile('5');
+
+ -- input: 9,10,2,3,5,8,1,4,6,7
+ input = LOAD 'input' AS (val:int);
+
+ grouped = GROUP input ALL;
+
+ -- produces: (1.0,3.0,5.0,8.0,10.0)
+ quantiles = FOREACH grouped generate Quantile(input);
