MemSQL is packaged as a compressed tar archive, or tarball, which contains its executable binaries. This tarball also contains metadata about MemSQL in a file named build_receipt.json.
The contents of the memsqlbin_amd64.tar.gz file are extracted to a folder named memsqlbin, and the build_receipt.json file is located in the following path: memsqlbin/utils/build_receipt.json
