The easiest way to start using the LLVM C++ API by example is to have LLVM generate the API usage for a given code sample. In this example it will emit the code required to rebuild the test.c sample by using LLVM:

$ clang -c -emit-llvm test.c -o test.ll
$ llc -march=cpp test.ll -o test.cpp

First a disclaimer: This is an experimental API that exposes internals that are likely to change in between different Spark releases. As a result, most datasources should be written against the stable public API in org.apache.spark.sql.sources. We expose this mostly to get feedback on what optimizations we should add to the stable API in order to get the best performance out of data sources.

We'll start with a simple artificial data source that just returns ranges of consecutive integers.

/** A data source that returns ranges of consecutive integers in a column named `a`. */
case class SimpleRelation(
    start: Int, 
    end: Int)(
    @transient val sqlContext: SQLContext)

Project

Description: What does this project do and who does it serve?

Project Setup

How do I, as a developer, start working on the project?

1. What dependencies does it have (where are they expressed) and how do I install them?
2. How can I see the project working before I change anything?
