kandi X-RAY | jones Summary
At their root, most configuration systems are a hierarchy of dictionaries. The root has config common to all environments, with config specific to say, developers or a staging area, inheriting and overriding values. Jones takes this idea and maps it to Zookeeper. Zookeeper is the ideal place for configuration. Besides it's availability guarantees, it's also able to update observers when data changes. Now we can change config at runtime, making possible a whole category of use-cases like switches, a/b tests, and knob and lever you can imagine. For more information, see my talk and presentation at Pycon Canada.

ANSWER
Answered 2021-Jun-16 at 02:44In the Map, set the value not to the cumulative total time for the employee so far, but to a whole employee object that contains the total time inside it. Spread the first object found so as not to mutate the input.

I'm using the cx_Oracle module to create an sqlalchemy engine and retrieve data from an Oracle database using Python and Pandas, but I have an issue with performance, and I'm getting database errors.
My code works OK (but slow) if I specify just a couple of columns, and after a long time I can get all the 3.5 million rows. Here's the code I'm using:
...ANSWER
Answered 2021-Jun-03 at 15:49I finally solved the issue by tuning the fetcharraysize and the prefetchrows attributes as suggested by Christopher Jones.
I dramatically improved the performance by setting the values of the attributes, and no more time-outs and error messages!
Thanks very much all who helped! :-)

I asked this question a few months back but now I'm working out of MS-Access and I'm unsure how to proceed. I have a query that lists the bldid, unitid, and resident id in separate columns. I'd like to modify the query output in Microsoft Access so that each resident that shares a building / unit shows as a new column on the same row as shown below. But since I'm limited to MS Access I can't seem to use with, cte, or rownumber. I'm at a loss as to how to do this so any help would be appreciated.
