Is it right to place a big 42mb json data file in repository , which is getting used by jmeter performance test suite?

In my project I have a sub-project in which jmeter performance related files are present now our requirement is to execute that suite with large data set . We are using json data sets here , so we have placed the json file in same directory where this jmeter jmx file is present. My concern is whether this is the right approach to place test data along with repository or not . This will increase the repository size unwantedly . Please suggest what other best ways I can use to solve this problem ?
