kandi X-RAY | stream-ops-java Summary

stream-ops-java is a Java library typically used in Utilities, JSON Processing, Kafka applications. stream-ops-java has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub, Maven.

Stream Ops for Java is a fully embeddable data streaming engine and stream processing API for Java. The data streaming engine and the stream processing API can be used together, or separately. Stream Ops addresses the same use cases as Kafka, but with some significant design differences which gives you a higher degree of architectural freedom. You can embed Stream Ops in a mobile app, desktop app, microservice, web app backend, and possibly also inside serverless functions like AWS Lambda etc. (we are still looking into how this can be done) and Google App Engine apps. Stream Ops design differences also supports a wider set of use cases than Kafka does out-of-the-box. We will describe these differences as the code that provides them is cleaned up and released. Stream Ops is developed by Nanosai:

st_read path for shinyapp in R

Asked 2021-Oct-03 at 00:33

Usually when st_read is used you put path in dsn, but in case of shiny if you put a full path inside dsn it will give an error as that file path does not exist on the server. So, now I put the shapefile in the www folder, but I don't know what path to put in dsn so that the app picks up the shapefile.

How can I fix this?

Current function code in the app:

Answered 2021-Oct-03 at 00:33

Thanks to Guillaumme for his comment, so I was able to fix the problem by first moving the shiny app to a R project. Then in the app code write st_read as follows, and the app is able to pick up the shapefile when its published on shinyapps.io.

Answered 2021-Aug-17 at 05:22

The evaluation of the JSON path is a bit different between the jsonb_path_xxx() functions and the equivalent operator. Most importantly you do not need the ? (...) condition as that is implied when using the operator.

The following should be equivalent:

The for loop statement seems to be wrong since dynJson is an object and not an array. You need to loop through the dynJson.orders, like below.

SSIS Script Task Fails with NewtonSoft.Json

Asked 2021-Jan-26 at 19:47

I have a C# code embedded in a script task in SSIS, and I installed NewtonSoft.Json for some json processing. When I run the package, below error shows up:

Could not load file or assembly 'Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

Despite trying all solutions and recommendations (uninstall & re-install the package, both from NuGet manager and through console, or adding the reference manually, etc.. ), whenever I run the SSIS package I still get the same error and the script task component fails.

I am using Visual Studio 2017 (SSDT).

How to solve the issue permanently?

Answered 2021-Jan-26 at 17:24

With SSIS, you can only reference assemblies installed on the GAC. Use gacutil, from Windows SDK to install the required assembly to the GAC

There is no way to make this dynamic. The number (and types) of all columns of a query must be known to the database when parsing the statement, long before it's actually executed.

If you always have the same structure you can create a type:

The problem mentioned here is described in this Github issue: https://github.com/FasterXML/jackson-dataformat-xml/issues/187

Basically what is happening is that Jackson is translating XML tree structure in JsonNode data model and this will not work as it's not supported.

There is 2 options described in that Github issue:

ANSWER

Answered 2020-Jul-16 at 18:20

Now that I see how you are deploying the app, I can say that this is expected behavior. Yes, your custom_shiny_deployment() has access to the data, but the deployed app does not because rsconnect::deployApp() does not ship objects from the calling environment. If you want the data to be available to the app, I recommend saving it (and tracking it with file_in() and file_out()) then passing it to the appFiles argument of deployApp() via custom_shiny_deployment().

EDIT

Your app.R can stay like it is.

app.R is the same as what you wrote.

Install stream-ops-java

The easiest way to use Stream Ops is via Maven. See the Maven dependency for Stream Ops in the next section. Alternatively you can clone Stream Ops and build it yourself. Stream Ops have 2 small dependencies which you may (or may not) have to clone too. That depends on what you are trying to do. The dependencies are also available from the central Maven repository though, so it is not necessary to clone and build them. Not unless you want to compile them all using a different Java version than the Java version they are currently built with.
