TM1 logins and logouts

[raulpkd]

Hi, I'm having a problem that while running an analytics program with a large dataset. The problem is that every request creates a login and login note to the login log. You can imagine the massive amount of rows being created. I wonder if it is possible to some use the same login session for multiple sessions, create a batch file for the requests or something else? This could reduce the stress on the login logging.

When you have multiple interactions with TM1 (e.g. data retrieval or writeback) from the same Python script there is no need to login for each operation separately.
Here is an example.

from TM1py.Services.TM1Service import TM1Service

tm1_params = {...}

with TM1Service(**tm1_params) as tm1:
    cells = {('e1', 'e2'): 1}
    tm1.cells.write_values("c1", cells)

    cells = {('e1', 'e2'): 2}
    tm1.cells.write_values("c1", cells)
    
    cells = {('e1', 'e2'): 3}
    tm1.cells.write_values("c1", cells)

Does that answer your question?
