Create distinct listing that includes all object types on gpfs.
Copy of the the list-path-external with the additional option.

These nodebooks use dataframes build from parquet files to sanity check
file listings from multiple sources.

These are use to create specific reports by opening the notebook
then copying it and modifying the parameters to a specific
policy run data set.

Their utility may be limited based on current parquet pipelines.

This is intended to be run on URL encoded output lines from a
gpfs list policy run.  It creates panda structures that are
then saved as parquet format for ease of downstream processing.

Can be run in parallel across many inputs by wrapping with papermill
and have upstream split the input file.

Makes it slightly more resilient and forms the foundation for
the parquet notebook.

Parameters hard coded to split on 50k enteries per file which provides
reasonable parallel read efficiency for downstream tasks.
Put splits in a .d subdir of file name.

Provide details on running a policy script with the provided
workflow framework.
Information on the list-policy-external policy and generated output.
Outline of future docs for preprocessing and reports.

This simplifies later report running to consolidating parsing and dataframe
create operations into a single batch.

Takes a directory of atime reports generated by array job and
merges into a single per-user report.

The report atime generator reads a provided input and generates
a per-user atime report.
The wrapper sbatch allows running the script in an array job
to support scaling across large data sets split into many files.

Figure out logic to parse list files and produce atime summaries.

The defer option with a list generates the list file outputs
according to the format described here:

https://www.ibm.com/docs/en/spectrum-scale/4.2.0?topic=pools-file-list-format

The file and ouput args control the location of the resulting file.

Pass the output are to the sbatch via env params.

Remove the hard-coded external script both because it is not needed
and because defer mode produces list output files directly.

The external script will be called with TEST parameter if the
policy is executed in test or prepare mode.
It will only get the LIST files to concat the ouput when the policy
is fully executed.

The policy file has both a LIST generation rule and a EXTERNAL LIST
consumer rule.  It uses the ESCAPE term to URL encode the ouput
generated by the LIST.
The external target script simply concats LIST files sent to it.
The mmapplypolicy command adds an additonal variable JOBID to
allow that to be passed as an OPT to the external script.
This let's us distinguish the ouput of one job from the next.

The mmpolicyapply list output file naming is not well documented.
Add job-specific subdir for global and scratch paths to isolate
expected files from a job.
Rename final tagged result and move it to the provided global
output dir and clean up the temporary dir after file completes.
Include potential for no output if there are zero matches.
