Support 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.

PVCs not created at all after deletion, when using Retail reclaim policy in corresponding StorageClass

Asked 2021-Jun-14 at 15:38

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 15:38

with 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.

I 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

room/SQLite background scheduler/trigger that runs automatically

Asked 2021-Jun-14 at 06:08

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 06:08

How 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

Usage example of pragma Task_Dispatching_Policy(Non_Preemptive_FIFO_Within_Priorities);

Asked 2021-Jun-13 at 17:46

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 17:46

I 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:

From 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.
