Answered 2021-Jun-14 at 16:35Support for _PIP_ADDITIONAL_REQUIREMENTS environment variable has not been released yet. It is only supported by the developer/unreleased version of the docker image. It is planned that this feature will be available in Airflow 2.1.1. For more information, see: Adding extra requirements for build and runtime of the PROD image.
For the older version, you should build a new image and set this image in the docker-compose.yaml. To do this, you need to follow a few steps.

QUESTION
I am using the ECK operator, to create an Elasticsearch instance.
The instance uses a StorageClass that has Retain (instead of Delete) as its reclaim policy.
Here are my PVCs before deleting the Elasticsearch instance
ANSWER
Answered 2021-Jun-14 at 15:38with the hope that due to the Retain policy, the new pods (i.e. their PVCs would bind to the existing PVs (and data wouldn't get lost)
It is explicitly written in the documentation that this is not what happens. the PVs are not available for another PVC after delete of a PVC.
the PersistentVolume still exists and the volume is considered "released". But it is not yet available for another claim because the previous claimant's data remains on the volume.
QUESTION
I am trying to use SqlDelight database in my app.
In my DAO, I have a function called getRecipeById to query the database and return a flow of domain model (Recipe). Here is the implementation of the function: (Note: RecipeTable is the name of the table, or I guess I should have called it RecipeEntity)
...ANSWER
Answered 2021-Jun-14 at 06:21I don't think MutableState is designed to be used in the ViewModel layer, since it's an observable integrated with the compose runtime.
You could create a MutableStateFlow instead and use collectAsState() from the view layer.
In your case the issue is probably, because of the state is captured in a coroutine invoked outside composition.
QUESTION
I've got a sample table:
I have a Sample table which has a "creationDate" as an atribute. What I want is a way to increment(update) the "numOfTimesUpdated" attribute each 24h since the creationdate. so lets say "creationdate" is 01.01.2021 12:12 AM => numOfTimesUpdated=0, 02.01.2021 12:12 AM => numOfTimesUpdated=1, 03.01.2021 12:12 AM => numOfTimesUpdated=3.
How can I implement something like this in the best way?
Does SQLite has some kind of background scheduler/trigger where a UPDATE Query gets automatically called? Or Is my only chance the client side(application) using smth. like an ApplicationManager?
...ANSWER
Answered 2021-Jun-14 at 06:08How can I implement something like this in the best way? You don't appear to even need a numberOfTimesUpdated column as the number of days since the creationDate can be calculated when required.
- If the date/time were stored in a supported format (e.g. YYYY-MM-DD HH:MM) it is very simple.
For example consider this :-

QUESTION
I have a large, heavily task oriented program, and I would like to explore variant scheduler policies. I am using Gnat Ada 2020. In particular, I would like to set the tasking model by use of the pragma:
pragma Task_Dispatching_Policy(Non_Preemptive_FIFO_Within_Priorities);
I don't think I understand the actual usage very well. I understand what the pragma does, but I am having difficulty placing the pragma correctly, at least according to GNAT. For various combinations of placement in the following small program, I always get the error : "incorrect placement for configuration pragma "Task_Dispatching_Policy" I have tried outside of the whole compilation unit, within the task type spec, within the task body spec, etc. Can anyone show me an example of usage of this pragma? Googling found many discussions but no actual examples of usage in source code. Thanks in advance.
...ANSWER
Answered 2021-Jun-13 at 17:46I am having difficulty placing the pragma correctly.
Focusing on correct placement, note that a Task_Dispatching_Policy pragma is a configuration pragma that must "appear before the first compilation_unit of a compilation."
at least according to GNAT.
As @egilhh comments, the GNAT User Guide describes how tp accomplish this in 3.4.1. Handling of Configuration Pragmas:
Configuration pragmas may either appear at the start of a compilation unit, or they can appear in a configuration pragma file to apply to all compilations performed in a given compilation environment.
In the case of a single compilation unit, simply place the pragma before the first context clause, as shown here:

Answered 2021-Jun-13 at 11:38From some research, it looks like computers have a hardware timer called a programmable interval timer (PIT), which the OS can use to set a time in the future to cause an "interrupt" in some milliseconds or nanoseconds in the future.

I'm beginner in Project Reactor and think it's pretty easy, but I can't find the solution.
I have N expensive tasks to do, and I want to implement something like Bounded Semaphore in Java (do not request next element until current count of running task less than K).
Shortly: complete all tasks, but no more K tasks at the same time

Install Scheduler
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
