NetLogo ABM Workflow System (NAWS) ===. Introduction --- NetLogo is a widely used agent-based modeling environment (but lacks support for scalable parallel execution. The NetLogo ABM Workflow System (NAWS) automatically decomposes large NetLogo ABM experiments defined using BehaviorSpace into multiple sub-experiments and executes them in parallel using one or more nodes. While BehaviorSpace supports multi-core parallelism it has been found to scale relatively poorly. NAWS divides the parameter space of a large experiment into multiple sub-experiments to be executed on one or more nodes without modification to a NetLogo ABM. Example --- 4. Enter into a directory with a NetLogo model with defined experiment.

QUESTION
Our team has started to use AWS and one of our projects will require storing approval statuses of various recommendations in a table.
There are various things that identify a single recommendation, let's say they're : State, ApplicationDate, LocationID, and Phase
. And then a bunch of attributes corresponding to the recommendation (title, volume, etc. etc.)
The use case will often require grabbing all entries for a given State
and ApplicationDate
(and then we will look at all the LocationId and Phase items that correspond to it) for review from a UI. Items are added to the table one at a time for a given Station, ApplicationDate, LocationId, Phase
and updated frequently.
A dev with a little more AWS experience mentioned we should probably use State+ApplicationDate
as the partition key, and LocationId+Phase
as the sort key. These two pieces combined would make the primary key. I generally understand this, but how does that work if we start getting multiple recommendations for the same primary key? I figure we either are ok with just overwriting what was previously there, OR we have to add some other attribute so we can write a recommendation for the State+ApplicationDate/LocationId+Phase
multiple times and get all previous values if we need to... but that would require adding something to the primary key right? Would that be like adding some kind of unique value to the sort key? Or for example, if we need to do status and want to record different values at different statuses, would we just need to add status to the sort key?
Does this sound like a reasonable approach or should I be exploring a different NAWS offering for storing this data?

Answered 2021-Sep-24 at 17:00Use a time-based id property, such as a ULID or KSID. This will provide randomness to avoid overwriting data, but also provide a time-based sorting of your data when used as part of a sort key
Because the id value is random, you will want to add it to your sort key for the table or index where you perform your list operations, and reserve the pk for known values that can be specified exactly.
It sounds like the 'State' is a value that can change. You can't update an item's key attributes on the table, so it is more common to use these attributes in a key for a GSI if they are needed to list data.
Given the above, an alternative design is to use the LocationId as the pk, the random id value as the sk, and a GSI with the GSI with 'State' as the pk and the random id as the sk. Or, if you want to list the items by State -> Phase -> date, the GSI sk could be a concatenation of the Phase and id property. The above pattern gives you another list mechanism using the LocationId + timestamp of the recommendation create time.

Install NAWS
You can use NAWS like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
