SSL Error for this driver does not really mean it's SSL ERROR, in most cases it could mean, that connection can't be established, from the first step. Check if port really available, you could try it by using some different tools, like DBeaver.

And unfortunately I can't recommend this driver you trying to use, it's unstable. May throw sigfault errors randomly and have other bugs. I would recommend using this driver instead, in most scenarios both are compatible, this one just more stable and predictible. And this driver used by lots of other Python projects, like SQLAlchemy, Django, irissqlcli, and more based on them.

Ages ago I've impleted project named BlocksExplorer, with a various of ways of using it

One of them is generating a picture of of the database, and visualization of defragmentation.

I think I tried it once on 2TB Database, but that was long time ago.

Anyway, this tool generates picture in BMP format, where each pixel represents each block in the database, so, for 

For 2TB database, it will be around 268435456 blocks, that will be a picture 16384x16384, and in BMP with a 3 bytes per pixel, it will be around 768MB for this picture, quite big one

This project is fully open, you can try to modify it a bit, and maybe if you do it per global, you will be able to make a map

did you try /usr/irissys/mgr/python, that's the path expected to be used by IRIS packages

pip install whatever --target /usr/irissys/mgr/python

and another place is /usr/irissys/lib/python, it's a place where InterSystems places Python Embedded support

sys.path, is a list of folders where python will look for the installed modules

Did you try using more appropriate package %Stream for it?

In your case, you would need to use %Stream.FileCharacter

 Set stream=##class(%Stream.FileCharacter).%New()
 $$$ThrowOnError(stream.LinkToFile("c:\export.csv"))
 set rs = ##class(%SQL.Statement).%ExecDirect(, "SELECT a, b FROM table")
 if rs.%SQLCODE'=0 {
     throw ##class(%Exception.SQL).CreateFromSQLCODE(rs.%SQLCODE, rs.%Message)
 }
 while rs.%Next() {
    set line = $listbuild(rs.a, rs.b)
    do f.WriteLine($listtostring(line, ","))
 }
 $$$ThrowOnError(stream.%Save())

Additionally, nowadays using embedded classes does not give much advantage, if it's not for one row result, only makes the code a bit harder to read

Implemented for Interoperability: it can check status, including items in it, restart, update, recover, and check for queues and errors.
There is also SQL Query executon

While we moved our application to AWS, and we have some data, which we need to keep for a while. With this feature, we can move old data to a cheaper storage.

I believe the ability to move to a cheaper storage is mostly the case. Another option is that some table is too big, and someone would like to split it to be stored in multiple different databases, together with the indexes.
