kandi X-RAY | concurr Summary

concurr is a Rust library. concurr has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This project is dual licensed under MIT and Apache 2.0. Originally inspired by the GNU Parallel project, and my previous re-implementation of the project in Rust, Concurr is a distributed and concurrent command-line job server & client architecture for generating and executing commands in parallel on any number of systems. At it's core, Concurr uses Tokio to perform asynchronous network I/O. The client works similarly to GNU Parallel, but there are key differences for the sake of simplicity in operation.

            Concurrent Counter Struct with Type Argument in Rust
            Asked 2021-Jun-15 at 23:55

            I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).

            Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?

            I thought that I could do this with generic type arguments:

            I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.

            Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:

            Swing JMenuBar not rendering properly
            Asked 2021-Jun-15 at 18:31

            First time actually using anything to do with swing - sorry for the poor code and crude visuals!
            Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
            But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

            The code for the visuals is as follows:

            You should separate creating your menu from your content. Please review the following example. I decoupled your menu, component, and event logic into meaningful phases.

            You are missing the listener type configuration so the default conversion service sees you want a list and splits the string by commas.

            If this isn't going to throw an exception then I don't know what is going to.

            This is caused by using blocking code within Netty's event loop.

            The code over here is making a blocking request 20 times in a row which cause the machine to break. I don't know what data is coming from the client but I would never recommend to do it in this manner.

            Azure Data Explorer High Ingestion Latency with Streaming
            Asked 2021-Jun-15 at 08:34

            We are using stream ingestion from Event Hubs to Azure Data Explorer. The Documentation states the following:

            The streaming ingestion operation completes in under 10 seconds, and your data is immediately available for query after completion.

            I am also aware of the limitations such as

            Streaming ingestion performance and capacity scales with increased VM and cluster sizes. The number of concurrent ingestion requests is limited to six per core. For example, for 16 core SKUs, such as D14 and L16, the maximal supported load is 96 concurrent ingestion requests. For two core SKUs, such as D11, the maximal supported load is 12 concurrent ingestion requests.

            But we are currently experiencing ingestion latency of 5 minutes (as shown on the Azure Metrics) and see that data is actually available for quering 10 minutes after ingestion.

            Our Dev Environment is the cheapest SKU Dev(No SLA)_Standard_D11_v2 but given that we only ingest ~5000 Events per day (per metric "Events Received") in this environment this latency is very high and not usable in the streaming scenario where we need to have the data available < 1 minute for queries.

            Is this the latency we have to expect from the Dev Environment or are the any tweaks we can apply in order to achieve lower latency also in those environments? How will latency behave with a production environment loke Standard_D12_v2? Do we have to expect those high numbers there as well or is there a fundamental difference in behavior between Dev/test and Production Environments in this concern?

            ...

            ANSWER

            Answered 2021-Jun-15 at 08:34

            Did you follow the two steps needed to enable the streaming ingestion for the specific table, i.e. enabling streaming ingestion on the cluster and on the table?

            In general, this is not expected, the Dev/Test cluster should exhibit the same behavior as the production cluster with the expected limitations around the size and scale of the operations, if you test it with a few events and see the same latency it means that something is wrong.

            If you did follow these steps, and it still does not work please open a support ticket.
