youvegotdata 1.0.0

Send new file notifications

youvegotdata

Uses RabbitMQ to send new file notifications, with the ultimate purpose of getting the file metadata into the Data Inventory Database.

The "producer" youvegotdata.py will usually be called by the CIRA data ingest scripts when a new file is added to the CIRA data stores, and will send a message through RabbitMQ to the consumers with the file's metadata.

Message "consumers" will be running to receive the file metadata and insert it into the database. It is expected that multiple consumers process will be accepting messages in RabbitMQ's "fair dispatch" configuration. A given notification will be received by one consumer.

Running youvegotdata.py

This must be run in a Python environment that includes pika - for connecting to RabbitMQ - and other needed packages. The environ-3.8.yml file in this repository can be used to create a workable conda environment. Setting one up using pip will certainly also work. Python 3.8 is the minimum version needed to run the script. Higher versions should work.

Copy the template-config.ini file to config.ini and edit the config.ini as described inside that file. Run the code with:

python youvegotdata.py [-h] [-v] [-p PRODUCT] [-r VERSION] [-s START_TIME] [-e END_TIME] [-l LENGTH] [-c CHECKSUM] [-t CHECKSUM_TYPE] filepath

Run this with the -h (--help) argument to see the available flagged arguments.

This will usually be run with just the filepath argument. An example is:

python youvegotdata/youvegotdata.py /full/path/to/local/file/data_file.hdf

If run from a local repository of this project.

The filepath file must exist on the local machine.
