To install the DeFi-Data-Engine, you need to meet the following requirements:

  • Installed and setup Java SE17 or later
  • Installed and setup MongoDB
  • Downloaded the two .jar executables found here

Meet the recommended minimum resources:

  • 16gb RAM or more
  • 4 core CPU or more
  • Storage equivalent to the amount of data to be used

Once setup, you can follow the general steps below to run the program. We will also go over an in-depth example for Linux (Centos7) however these steps can be applied to any OS.

General Steps:

  1. Open two terminals (can be completed in 1 however it is easier in two).
  2. Navigate to the folder containing the two downloaded .jar files.
  3. Start the DeFi-Data-Engine.jar file using the following command: java -jar DeFi-Data-Engine.jar
  4. You should see the following two lines (note the timestamps are arbitrary). These show that the engine is waiting for the REST API connection.
[2022-12-04 14:40:53.628349081] [Thread-0  ] PACKET   - [COR -> ENG] [STRT] [{}]
[2022-12-04 14:40:53.629936024] [Thread-0  ] PACKET   - [ENG -> OUT] [STRT] [{}]
  1. Start the rest-connection-4.3.3.jar using the following command: java -jar rest-connection-4.3.3.jar
  2. The REST API should now show a generic spring bootup sequence. The engine should now print the following lines signifying the setup is complete:
[2022-12-04 14:41:38.623249482] [Thread-0  ] INFO     - [Successfully connected to reserved socket. Key <rest-key-reserved>]
[2022-12-04 14:41:38.628060474] [Thread-0  ] RESPONSE - [200] [Successful Response.] []
[2022-12-04 14:41:38.628340861] [Thread-0  ] PACKET   - [ENG -> LSH] [INIT] [{source=mongo_db}]
[2022-12-04 14:41:39.027234662] [Thread-0  ] RESPONSE - [200] [Successful Response.] []
[2022-12-04 14:41:39.027519057] [Thread-0  ] RESPONSE - [200] [Successful Response.] []
  1. Now disown the instances however your OS permits it.
  2. The engine is now successfully running and can be accessed as intended.
