Hi Everyone!

We have an existing process (running in FIFO order), all business hosts having pool size=1.

Currently we are reading records from a file (one record at a time) then that record goes to business process for further processing and finally through the business operation. As of now we are using synchronous call in our existing code. Before processing the last record we are using hang of 50 seconds because we need to initiate a batch once the processing of last record is finished.

Hi Developers!

Sometimes we need to deal with classes/tables where the primary key and the IdKey are something that is maintained by yourself.

What is the proper way to generate a new ID in case where ID is a %BigInt?

Property id As %Library.BigInt

Are there any system methods to provide it?

There is data already imported via SQL, so there is no last ID stored in ^myclassD, so I cannot do $I(^myclassD).

Thinking of:

Hello community!
I have a small challenge for you :)

One of customers is sending quite a lot of messages between interoperability components, which mix standard request content and streams representing serialized JSON objects. As these JSON streams can be quite long (but not too long, just couple hundreds of characters) they would appreciate if the JSON content of stream was displayed in a nice-to-read way, using syntax highlighting by message trace view.

Code Golf: Binary encoding!

Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

  • First Step: Reverse Cipher

    • Reverse the entire input string.
    • Relocate the last character of the original string (now the first character of the reversed string) to the end.

  • Second Step: Alphabetic Index Binary Encoding

Dear Community members,

We are currently performing technical work, and during this time, you may experience issues with the Developer Community portal, Developer Community AI, and search functionality:

🔹 Ask DC AI is temporarily unavailable
🔹 Search may take longer than usual or may not return results
🔹 You may experience problems with logging into the Developer Community and Open Exchange

We’re working to restore full functionality as quickly as possible. Thank you for your patience and understanding.
