MATLAB Interface for AWS Athena

MATLAB® Interface for Amazon Web Services Athena™ Service. Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. This package provides a basic interface to a subset of Athena features from within MATLAB.

Requirements

MathWorks products

• Requires MATLAB release R2017b or later.
• AWS Common utilities found at https://github.com/mathworks-ref-arch/matlab-aws-common

3rd party products

• Amazon Web Services account

To build a required JAR file:

• Maven
• JDK 8+

Getting Started

Please refer to the Documentation to get started. The Installation Instructions and Basic Usage documents provide detailed instructions on setting up and using the interface. The easiest way to fetch this repository and all required dependencies is to clone the top-level repository using:

git clone --recursive https://github.com/mathworks-ref-arch/mathworks-aws-support.git

Build the AWS SDK for Java components

The MATLAB code uses the AWS SDK for Java and can be built using:

cd matlab-aws-athena/Software/Java
mvn clean package

Once built, use the matlab-aws-athena/Software/MATLAB/startup.m function to initialize the interface which will use the AWS Credentials Provider Chain to authenticate. Please see the relevant documentation on how to specify the credentials.

Using the interface

% Create some data needed in the examples
dbName = 'MyAirlines.airlines';
resultBucket = 's3://testing/airlineresult';
distLimit = 1000;

% Create the client object and authenticate using 
%   the AWS Default Provider Chain
ath = aws.athena.AthenaClient();
ath.Database = dbName;
ath.initialize


% Create a SQL statement and execute it (asynchronously)
queryFar = sprintf('SELECT UniqueCarrier, distance FROM %s WHERE distance > %d;', ...
    dbName, distLimit);
resultIDFar = ath.submitQuery(queryFar, resultBucket);

% Check the status, and make sure it says 'SUCCEEDED'
status = char(ath.getStatusOfQuery(resultIDFar));

% At this point, we can read the results by using a MATLAB datastore
resFile = sprintf('%s/%s.csv', resultBucket, char(resultIDFar));
ds = datastore(resFile);
ds.NumHeaderLines = 1;
farResult = ds.readall();
