Chronicle | Implementation of saga pattern for .NET Core

Is there any reasonable way to read or write to a Chronicle Queue from a C# application? It runs on Mono on Linux if that matters.

One of our system has a micro service architecture using Apache Kafka as a service bus. Low latency is a very important factor but reliability and consistency (exactly once) are even more important.

When we perform some load tests we noticed signifiant performance degradation and all investigations pointed to big increases in Kafka topics producer and consumer latencies. No matter how much configuration we changed or more resources we added we could not get rid of the symptoms.

At the moment our needs are processing 10 transactions per second (TPS) and the load test is exercising 20 TPS but as the system is evolving and adding more functionality we know we'll reach a stage when the need will be 500TPS so we started being worried if we can achieve this with Kafka.

As a proof of concept I tried to switch to one of our micro services to use a chronicle-queue instead of a Kafka topic. It was easy to migrate following the avro example as from Chronicle-Queue-Demo git hub repo

I am working on some code for an online bible. I need to identify when references are written out. I have looked all through stackoverflow and tried various regex examples but they all seem to fail with single books (eg Jude) as they require a number to proceed the book name. Here is my solution so far :

I am working on a product page where the user has an option to filter on different boardgames. What I want to do is to give the user an option to filter on time, category of the game, number of players and age. When the user enters a checkbox on all 4 options there should be some games recommended based on the criteria. However when I check multiple boxes I get no result, what am I doing wrong? (I have more games in my file but post small amount)

Here's my code:

I would like to implement functionality for being able to search a QPlainTextEdit for a query string, and display all matched lines in a table. Selecting a row in the table should move the cursor to the correct line in the document.

Below is a working example that finds all matches and displays them in a table. How can I get to the selected line number in the string that the plaintextedit holds? I could instead use the match.capturedEnd() and match.capturedStart() to show the matches, but line numbers are a more intuitive thing to think of, rather than the character index matches.

I have the .rmd file below and I display it via a shiny app. I want to change the background color to white in the whole space that is included into these 6 columns space and not only the titles. How can I do this? The remaining 6 columns (3 left, 3 right) should remain the same color.

I have the shiny app below in which I want to put in the header an image, a title and four actionbuttons like in the attached screenshot. The 4 buttons should be below the title and not cover the image. How can I adapt it? Does it depend on screen resolution? The font and font sizes should not change.

It should be like:

I have some code that goes through the cast list of a show or movie on Wikipedia. Scraping all the actor's names and storing them. The current code I have finds all the in the list and stores their title tags. It currently goes:

Each example of Chronicle map needs to be given an "entries" size in the builder but I don't understand the impact this value has on a persisted map:
