youvegotdata 1.0.1

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.

Installing youvegotdata

This module requires Python 3.8 or greater. It is deployed to PyPi, so it can be installed with:

pip install youvegotdata

Which will install the ygd CLI command in your current Python environment.

Running youvegotdata.py as ygd

Create the ~/.config/youvegotdata/ directory if it does not already exist. Create a config.ini file in this directory that looks like:

[Settings]
RMQ_HOST = <host of the RabbitMQ server>

And fill it in with the RabbitMQ server's host name.

Run the code with:

ygd [-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:

ygd /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.
