I believe there are several differences between these 2 technologies, but I would summarize the key things as below. As Tim mentioned, it finally depends on your use case. So if you can highlight little bit on what you trying to do, may we can answer more specific.
----------- - Drill provides ANSI SQL. This means that all the BI/Analytics and SQL tools can work as is with Drill using JDBC/ODBC. Druid provides REST APIs as the query layer.I am not sure if Druid has SQL layer at all (don't see it in their docs) - Query flexibility is high with Drill. For ex: Druid supports groupBy style queries, but doesn't support JOINs. Drill supports all the key analytic functionality such as JOINs, aggregations, sort, filters, wide variety of functions to operate on data which makes it suitable for a more broader set of use cases - Drill supports queries natively on Hadoop data formats (JSON, parquet, Text as well as all Hive file formats). You don't need to load or copy the data into a specific format in order to do queries. - Drill can do direct queries on self-describing data such as JSON, Parquet, HBase without defining schema overlays in Hive. You can take a look at the "Apache Drill in 10 mins doc" below to get started with Drill around some of these capabilities. https://cwiki.apache.org/confluence/display/DRILL/Apache+Drill+in+10+Minutes Hope that helps. -Thanks Neeraja On Tue, May 6, 2014 at 2:23 PM, Timothy Chen <[email protected]> wrote: > Hi Pujari, > > It's hard to compare something without knowing what is your > requirements and you're trying to achieve. > > Just in general though Drill is not ready for production as we are > moving towards beta, but definitely like to have hands on trying it > and get more feedback and what usecases people are interested in. > > Tim > > On Tue, May 6, 2014 at 10:42 AM, Pujari Pradeep - ppujar > <[email protected]> wrote: > > Hi All, > > > > I attended the first Apache Drill Design meeting and then disconnected. > My > > priority was different at that point.
