In our benchmark, we instruct the Crail shuffler to use a Radix sorter instead. The Radix sorter cannot be applied to arbitrary objects but works well for keys of a fixed byte length. The standard pipeline of a reduce task is to first deserialize the data and then sort it. In the particular configuration of the Crail shuffler, we turn these two steps around and first sort the data and deserialize it later. This is possible because the data is read into a contiguous off-heap buffer that can be sorted almost in-place. @@ -255,13 +255,13 @@ The figure below shows the overall performance of Spark/Crail vs Spark/Vanilla o </div> <p><br /></p> -<div style="text-align:center"><img src="http://crail.incubator.apache.org/img/blog/sort/performance_overall.png"; width="470" /></div> +<div style="text-align:center"><img src="//crail.incubator.apache.org/img/blog/sort/performance_overall.png" width="470" /></div> <p><br /><br /></p> <p>One key question of interest is about the network usage of the Crail shuffler during the sorting benchmark.
