Constructor parameter should be str in Notebook
I have a Python 3 Neptune Notebook. When I try to run a command such as
result = g.V().has('code','test').valueMap().toList()
print('result is ' + str(result))
I get:
**~/anaconda3/envs/JupyterSystemEnv/lib/python3.6/site-packages/yarl/_url.py in __new__(cls, val, encoded, strict)**
**156 val = urlsplit(str(val))**
**157 else:**
**--> 158 raise TypeError("Constructor parameter should be str")**
**159**
**160 if not encoded:**
**TypeError: Constructor parameter should be str**
This is a new error, these commands worked for the past year or so. This is a similar error I get in python when I use Python 3.8 instead of 3.7 to call Neptune... is it possible for me to change the notebook Python to 3.7?

Over the past week or so, in order to run a notebook I have been downgrading my notebook using this command:
%%bash
aws s3 cp s3://aws-neptune-notebook/graph_notebook.tar.gz /tmp/graph_notebook.tar.gz
rm -rf /tmp/graph_notebook
tar -zxvf /tmp/graph_notebook.tar.gz -C /tmp
/tmp/graph_notebook/install.sh -v="3.0.6"
to run the code. Now I am unable to downgrade the notebook, when I try I get this:
**WARNING: Skipping NeptuneGraphNotebook as it is not installed.**

Impact and examples 1.0.4.1.R2.1
I noticed 1.0.4.1.R2.1 was released recently with a vague description of fixes...
"Disabled an optimization for Gremlin conditional insert patterns which can add or append to existing labels and properties"
I'm trying to determine if our team has been impacted and whether we need to cleanup any bad data.
Could example queries be provided that were affected?
Are there ways to detect if Nodes/Edges have been affected by this bug?

I can query up to around 20 of them but more of them I get this error (only 31 total)
The vertices are all of one type/label - query is g.V().hasLabel('DATALABEL').valueMap(true).toList()
the vertices do have a good few properties including set property types of json strings

How are Neptune I/O's calculated for billing purposes?
I've just started experimenting with Neptune for the past month, and my usage has been pretty minimal. I've probably only got about a dozen nodes in the database, and I've been doing some queries through the Gremlin Console and through AWS Lambda functions just to familiarize myself with how things work. I'm the only person who has access to this account.
I just got my first month's bill, and it says that I've had 797,681 I/O's, which seems impossible! I'm not worried about the $0.16 charge for that this month, but I'm pretty concerned about how this might scale.
I've only had one Neptune cluster running for a total of 124.266 hours this month. I'd estimate that as much as 25% of that time I wasn't interacting with the cluster at all. When I was interacting with it, however, I'd estimate I was only submitting about 100 queries in an hour at the very most, and often much less than that. Yet, at 797,681 I/O's in my billing, that works out to an average of 6,419 queries per hour!
Am I missing something here? How does Amazon calculate I/O's? I had assumed that a single, multi-step query would count as a single I/O, but might it actually count as 100's of I/O's, assuming that there are multiple steps, and each of those steps may need to touch multiple quads in order to find the desired information? If that's the case, it seems like the cost has the potential to quickly get out of hand. If someone could clarify how I/O's are calculated, I'd appreciate it!

Vertex Dropping Issues
Hello,
I have 1 million + vertices in Neptune with the following property: ('__graph','db8db2af-8b0c-49fb-bcf1-c44cae2d2e95')
I want to purge all 1 million vertices in the database. I know i'll have to drop the vertices in small chunks, otherwise the query will time out. Each chunk will be responsible for deleting 1000 vertices, which takes about 2 seconds normally. This is what the query looks like for a chunk:
g.V().has('__graph','db8db2af-8b0c-49fb-bcf1-c44cae2d2e95').limit(1000).drop()
I'm going to show you what the profile looks like after performing the operation twice:
gremlin> g.V().has('__graph','db8db2af-8b0c-49fb-bcf1-c44cae2d2e95').limit(1000).drop().profile()
==>Traversal Metrics
Step Count Traversers Time (ms) % Dur
=============================================================================================================
NeptuneGraphQueryStep(Vertex) 1 1 2020.007 99.99
NeptuneDropStep 0.101 0.01
>TOTAL - - 2020.109 -
-----
gremlin> g.V().has('__graph','db8db2af-8b0c-49fb-bcf1-c44cae2d2e95').limit(1000).drop().profile()
==>Traversal Metrics
Step Count Traversers Time (ms) % Dur
=============================================================================================================
NeptuneGraphQueryStep(Vertex) 1 1 57883.392 100.00
NeptuneDropStep 0.130 0.00
>TOTAL - - 57883.522 -
Why is dropping so inconsistent? It typically should take 2000ms, however we are seeing large spikes in time like the second example. A lot of the time the query completely times out after 2 minutes.
Please help,
Thanks,
Austin
