QUESTION
From Spring boot project we are calling GraalVM for processing some rules written in JavaScript. But when I am calling GraalVM using multiple threads, it is giving the below exception. If we use synchronized then the below issue is not coming. I know JavaScript runs on a single thread but I wanted to run graalVM using multiple threads. Is there any way to run multiple GraalVMs on multiple threads simultneously?
Some more details about project structure: I have kafka consumer, which is receiving huge messages from Kafka topics and then calling graalvm to process them using some JavaScript rules.

...ANSWER
Answered 2020-Aug-17 at 13:16Yes you can run multiple GraalVM contexts simultaneously.
As described in the following article: https://medium.com/graalvm/multi-threaded-java-javascript-language-interoperability-in-graalvm-2f19c1f9c37b
GraalVM’s JavaScript runtime supports parallel execution via multiple threads in a simple yet powerful way, which we believe is convenient for a variety of embedding scenarios. The model is based on the following three simple rules:
- In a polyglot application, an arbitrary number of JS runtimes can be created, but they should be used by one thread at a time.
- Concurrent access to Java objects is allowed: any Java object can be accessed by any Java or JavaScript thread, concurrently.
- Concurrent access to JavaScript objects is not allowed: any JavaScript object cannot be accessed by more than one thread at a time.
GraalVM enforces these rules at runtime, therefore making it easier and safer to reason about parallel and concurrent execution in a polyglot application.
So when you're trying to access a JS object (function) concurrently from multiple threads, you see the exception you showed.
What you can do is ensure that only 1 thread has access to your JS objects. One way to do this is to use synchronization. Another -- creating multiple Context objects 1 per thread.
This approach is used in this demo application: https://github.com/graalvm/graalvm-demos/tree/master/js-java-async-helidon
it uses a context provider helper class:
QUESTION
I worked on creating a SSIS datamigration using kingswaysoft for Dynamics. i was tried to migrate createdon field from source to destination, once migrated there is a time difference of 12 Hrs, CRM time zone is set to GMT+12 for both source and destination, it looks like its migration time in UTC so is there a way in SSIS packages to convert UCT to GMT+12? or is there any expression i can use to solve my problem.
ANSWER
Answered 2020-Jul-22 at 12:39In our CDS/CRM Source component, there is an option to select the Output Timezone. The Output Timezone option specifies how CRM datetime values are produced. There are three options available.
- UTC (Default)
- Adjust to timezone of Connection User
- Adjust to timezone of Impersonation User
If you are going to use "Adjust to timezone of Impersonation User", make sure that you have the "Impersonate As" set.
Similarly, our CDS/CRM Destination Component includes an optional setting to "Send datetime values in UTC format". This option indicates whether datetime values should be submitted to CRM server in UTC format. This option will apply to all datetime fields when selected. When not selected, the datetime values are submitted based on the timezone setting of the connection or impersonation user.
Finally, our SSIS Productivity Pack also includes the Time Zone Conversion component which is used to convert values from a date column from one time zone to another. The component also automatically adjusts for daylight saving changes when converting between different time zones including UTC.

QUESTION
I'm having a lot of issues migrating a localhost Cosmos DB database hosted in the Cosmos DB Emulator to an online Cosmos DB instance on Azure. I have used Microsoft's data migration tool to upload the current database, converted to JSON files, to a storage account, and using a Data Migration Service to pull the data from the storage account, to the Cosmos DB database, according to the steps shown here.
At the start of the migration, i get the following fatal error:
Cannot deserialize a 'BsonDocument' from BsonType 'Array'
I don't know how to proceed. Does anyone have experience with such conversions and know how to get past this error?
...ANSWER
Answered 2019-Dec-09 at 09:26For when others encounter this same problem in the future: I applied the following to make this work:
- Download Mongodump Full MongoDB Server download here
- Dump the Cosmos DB emulated database using mongodump
- Copy the resulting .bson and metadata files to an Azure Storage account (Blob storage)
- Get a SAS url for this account using Azure Storage Explorer
- Create a new Azure Database migration service (MongoDB => Cosmos DB (MongoDB API))
- Set Azure Storage as source, and enter the SAS url
- Set your Cosmos DB database as the target
Using mongodump, the data gets generated into a file structure which Cosmos DB understands.

QUESTION
This issue is only present on the server I've published to. Locally I'm having zero issues.
After publishing from VS2017, the web page is displaying an Internal Server error with no further description on that page. This is not the first time I've published, so this issue is very random.
I'm at my wits end and am totally stumped as to what's causing this. Especially since before I hit publish, it was working fine. Although, it has been quite awhile since I've published from VS.
Things I've tried:
- Restarting Server
- Repairing IIS and ensuring correct .net core versions are installed.
- More server restarting
- Ensuring correct DLL's are present(even though this isn't first time publishing)
- Check connection strings in appsettings
- View stdoutLog output
- View event log - this didn't display anything helpful

ANSWER
Answered 2018-Oct-18 at 17:05This is a log warning to tell you that this package is not ready to support async syntax, and this is true, we released the first part of the runtime in msrest 0.6.0, but we didn't released any packages with async support yet.
For reference that it's just a warning: https://github.com/Azure/msrest-for-python/blob/master/msrest/async_paging.py#L40
It will not impact any code and will not raise any exception. You will get a problem only if you try to use async for of async syntax (because as the warning tells you, it's not ready for).
When we'll start shipping async compatible packages by the end of this year, this warning will disappear automatically as more and more package becomes ready.
If this warning is really a problem for you, you can disable the logger "msrest.async_paging" or pin msrest to 0.5.5 (before async core support).
Feel free to open an issue on our tracker if you feel this is really a massive problem, and depending on how many people I get bad feedback, I might change it to debug for a few months. But once async packages will be released, it will be an important source of feedback and I truly think it would deserve a warning. https://github.com/Azure/azure-sdk-for-python/issues
Thank you for your feedback!
(I own this code at Microsoft).
Edit: Being that you're not the only one with questions about this, I released a 0.6.1 that removes this warning.
