PQL stands for Python-Query-Language. PQL translates python expressions to MongoDB queries. PQL uses the builtin python ast module for parsing and analysis of python expressions. PQL is resilient to code injections as it doesn’t evaluate the code.

. As a workaround, using Tex
instead would also work as long as you have LaTeX installed.

I'm using Prisma 3.7.0 and Postgresql 13. I need to create a many-to-many relation between two models that has some additional data, but I don't know how to do this in a Prisma schema. The fields I want to add are not appropriately added to either table.
Here's some simplified (contrived) SQL to illustrate the goal:
It's pretty straight-forward in SQL, but I don't quite understand from the Prisma docs how to do it.

I have a table, ProcessQueueLog
, that contains a delimited field value that I need to split and join to another table. I have a working statement but it seems rather slow. Can someone advise a better method?
fn_SplitString
was written inhouse by a long-gone dev. It returns part1 and part2 and is rather typical of any split string function.

QUESTION
We need to Monitor disk space usage for Kafka Brokers running in AWS MSK cluster.
There're several metrices emitted by Kafka which can be used to monitor various aspects. But I was unable to find any specific metric that monitors "Disk Usage" for each broker.
Although, it depends on message and log retention policy and the rate at which new events are coming in various topics, how we can predict if our brokers go out of disk in next 1 days (or whatever duration we want as safe threshold).
If we can monitor the average size of event payload and events per minute (or hour), it can help in making this calculation. I was referring to Apache Kafka documentation for available metrices, but I was unable to find this as well.
...ANSWER
Answered 2021-Jun-02 at 02:41available metrices for node filesystem can be used directly. Kafka does not expose any specific metrics for this purpose. So I re-used following metrices used for eks cluster:
QUESTION
I need to write a script that connects an ERP program to a manufacturing program. With the production program the matter is clear - I send it data via HTTP requests. It is worse with the ERP program, because in its case, the data must be read from a DBF file.
I use the dbf library because (if I'm not mistaken) it's the only one that provides the ability to filter data in a fairly simple and fast way. I open the database this way
...ANSWER
Answered 2021-Jan-29 at 14:34I came to the conclusion that I have to use encoding directly when reading the DBF database. However, I could not read from the documentation, how exactly to do this.
After a thorough analysis of the dbf module itself, I came to the conclusion that I need to use the codepage parameter when opening the database. A moment of combining and I was able to determine that of all the encoding standards available in the module, cp852 suits me best.
After the correction, the code to open a DBF database looks like this:
QUESTION
I have lots of recruitment data that i want to re-arrange, separate and modify using arrays. The data includes all information from 1st stage, 2nd stage and 3rd stage interview for each candidates. The idea is to separate each stage onto their own sheets (e.g. Interview 1, interview 2, interview 3). And then to also create a table that has information from all three stages for each candidate.
Firstly, i have created an array of all the data by declaring the range ("A1:AV10000") as a variant.
Then i have created a loop to loop through this data, and separate each type of event that occurs into their own arrays, using an IF function within the loop. If condition is met, create a new array and add each row that condition is met to an array.
However, i believe my arrays are being made into a 3D array and i am sure how to edit the code so that it remains 2Darray. I understand why the code may be creating 3D array (due to iterating by 1 in the loop), however i am unsure how to write code so it includes all data the row and only iterates as shown below.
e.g. currently it goes (1)(1,1),(1)(1,2) then (2)(1,1),(2)(1,2) then (3)(1,1),(3)(1,2). I would think it would work if it was (1,1)(1,2) then (2,1)(2,2) then (3,1)(3,2). Screenshot of array format from local window
