Unfortunately, this fails to scale + without compression. + + JavaEWAH is a word-aligned compressed variant of the Java bitset class. It uses a 64-bit run-length encoding (RLE) + compression scheme. We trade-off some compression for better processing speed. We also have a 32-bit version which + compresses better, but is not as fast. + + In general, the goal of word-aligned compression is not to achieve the best compression, but rather to improve query + processing time. Hence, we try to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme we + implemented is always more efficient storage-wise than an uncompressed bitmap as implemented in the BitSet class). + Unlike some alternatives, javaewah does not rely on a patented scheme. + + It includes exhaustive unit testing. As of November 2011, Apache Maven is used to build and validate the releases. + (Building the source code with javac remains trivial). + + Usage: + + // set bits at pos. 0, 2, 64, and 1<<30 to value "true" (others are false) + EWAHCompressedBitmap ewahBitmap1 = EWAHCompressedBitmap.bitmapOf(0,2,64,1<<30); + EWAHCompressedBitmap ewahBitmap2 = EWAHCompressedBitmap.bitmapOf(1,3,64,1<<30); + EWAHCompressedBitmap xorbitmap = EWAHCompressedBitmap.xor(ewahBitmap1,ewahBitmap2); + int[] setbits = xorbitmap.toArray();// which bits are set? + +\u001B[1mSEE ALSO\u001B[0m + \u001B[36mhttp://code.google.com/p/javaewah/\u001B[0m http://git-wip-us.apache.org/repos/asf/servicemix-bundles/blob/b51292c5/pom.xml ---------------------------------------------------------------------- diff --git a/pom.xml b/pom.xml index 81ef32e..60ee61f 100644 --- a/pom.xml +++ b/pom.xml @@ -88,6 +88,7 @@ <module>bcprov-jdk15on-1.52</module> <module>aws-java-sdk-1.9.33</module> <module>lightcouch-0.1.8</module> + <module>javaewah-1.0.2</module> </modules> </project>
