I have a schema with many large tables which all have the same structure. Each table has an index on its id. I also have a separate table with all the id's across the other tables, pointing to their tablename; for example, the tables in the schema:

I read this answer, which clarified a lot of things, but I'm still confused about how I should go about designing my primary key.

First off I want to clarify the idea of WCUs. I get that WCU is the write capacity of max 1kb per second. Does it mean that if writing a piece of data takes 0.25 seconds, I would need 4 of those to be billed 1 WCU? Or each time I write something it consumes 1 WCU, but I could also write X times within 1 second and still be billed 1 WCU?

Usage

I want to create a table that stores the form data for a set of gyms (95% will be waivers, the rest will be incidents reports). Most of the time, each forms will be accessed directly via its unique ID. I also want to query the forms by date, form, userId, etc..

We can assume an average of 50k forms per gym

Options

• First option is straight forward: having the formId be the partition key. What I don't like about this option is that scan operations will always filter out 90% of the data (i.e. the forms from other gyms), which isn't good for RCUs.

• Second option is that I would make the gymId the partition key, and add a sort key for the date, formId, userId. To implement this option I would need to know more about the implications of having 50k records on one partition key.

• Third option is to have one table per gyms and have the formId as partition key. This seems to be like the best option for now, but I don't really like the idea of having a a large number of tables doing the same thing in my account.

Is there another option? Which one of the three is better?

Edit: I'm assuming another option would be SimpleDB?

I am pretty new to python and I am trying to sort through a directory's files that start with 'O0' and copy any string in the text files that has an 'F', 'T', or 'S' in them, and paste, preferably just that string, (but the whole line would still work) in a new text file, preferably on the desktop. It is making the text file, but it is blank, and python does not close the file. Here's what I have so far:

I have a given, unmodifiable table design which resembles:

I create a Pentest tool for educational purposes, so the old version was written using python 2, then I convert it to python 3 and when I try to run the main file pxxtf.py I got multiple errors, I correct most of them but for this one about Circular Import, I try multiple fixes from forums and StackOverFlow and nothing work with me.

When I try to run the main script :

I build a script to filter several Messages out of a log file. The file im using right now has around 400.000 lines and when im looking for a match with the following code he takes very long since i added the progress bar. Is there a way to make it more efficient. If im right the reason for it to take so long is that he refreshes the progressbar Gui with every line he passes.

Starting with the sample from https://docs.gradle.org/current/samples/sample_jvm_multi_project_with_code_coverage.html (i.e., the code here https://github.com/gradle/gradle/tree/master/subprojects/docs/src/samples/java/jvm-multi-project-with-code-coverage ) and simply adding Spring Boot by changing application/build.gradle to

I am new to spring boot and trying to figure out some of its working. Here I am getting Null Pointer Exception for the below implementation. I am not sure can we use @Autowire annotation for a Library project without a Main class. Maybe this sounds stupid,I believe we can do a @ComponentScan for the Library Project from a Service project that's created.My Question is looking at the below implementation is there any possibility to use annotation in the below library project, because Annotations are throwing NullPointerException for the below code?

Library

The below code is a library and it Doesn't have a Main Class

I have made a code to store each appointment calendar given by user to an ArrayList. Each ArrayList contains title, description, date and time.

Now I want to make an option for the user to edit the data of appointment calendar of their choice.

I use the appointment calendar's title for the comparison. Here's the code:
