    <title>question Re: kudu is slower than parquet? in Support Questions</title>

    <description>Please share the HW and SW specs and the results. I am quite interested. As pointed out, both could sway the results as even Impala's defaults are anemic.&lt;BR /&gt;&lt;BR /&gt;Also, I want to point out that Kudu is a filesystem, Impala is an in-memory query engine. Parquet is a file format.&lt;BR /&gt;&lt;BR /&gt;So what you are really comparing is Impala+Kudu v Impala+HDFS. You should be using the same file format for both to make it a direct comparison. Also, I don't view Kudu as the inherently faster option. Yes it is written in C which can be faster than Java and it, I believe, is less of an abstraction. Anyway, my point is that Kudu is great for somethings and HDFS is great for others. It isn't an this or that based on performance, at least in my opinion.</description>
