stormRoomOccupancy | basic Storm topology that updates DB persistent state | Database library

I want to be able to (at run time) create or alter a DB schema dynamically on a particular event (e.g. click of a button) using FormHandler microservice of Gramex.

I am getting the following error while trying to upload a dataset to Hub (dataset format for AI) S3SetError: Connection was closed before we received a valid response from endpoint URL: "<...>".

So, I tried to delete the dataset and it is throwing this error below.

CorruptedMetaError: 'boxes/tensor_meta.json' and 'boxes/chunks_index/unsharded' have a record of different numbers of samples. Got 0 and 6103 respectively.

Using Hub version: v2.3.1

I ran into an issue that I haven't found a solution to yet. I have a collection with dozens of documents that every one of the documents contains a list (let's use the name 'list' as a key for that list) with ids of other documents(they are connected in some way).

some of the documents in the collection were deleted and I try to find all the documents that contain the ids of documents that do not exist anymore in the collection.

example:

As to the example above: I want to get the document with the id : 5e3266e9bd724a000107a902 because it contains a list with the id 5e32a7f7bd724a00012c1104 that does not exist anymore.

Given a connection to the PostgreSQL database for user 'Alice', is there a statement that could be executed to switch to user 'Bob'?

Motivation: Looking to avoid having separate pools for each user (i.e. re-use a connection that was previously used by another user).

I made login page and now i'm trying to replace simple user.js to Sqlite Database (react-native-sqlite-storage). When i launch my project with database, i get this error.

As the title suggests I'm wondering how to create an effective index for GROUP BY queries in CosmosDB.

Say the documents look something like:

Doing a query to find out the SUM of the speed grouped by the partition key would look something like:

With about ~1.6 million documents this query costs 1489.51 RUs. However, splitting this up into two queries such as:

each of them cost only ~2.8 RUs each. Obviously the results would need some post-processing compared to the GROUP BY query to match. But a total of 5.6 RUs compared to 1489 RUs makes it worth it.

The indexing on the collection is as follows:

Am I completely missing something or how can the GROUP BY be so much more expensive? Is there any indexing I can do to bring it down?

Thanks in advance!

i have a database field that is set to decimal, while in my Go project i am having problem choosing which datatype can be use. each time i send a create reuquest to my code, i get a "cannot marshal 'decimal' into #golang datatype#

Thansks for your Help in Advance

I want to copy one big database table to another. This is my current approach:

But the problem is that I get a error "Enterprise]ASE has run out of LOCKS". I tried to use COMMIT statement after insert some piece of records, but it closes the cursor. I don't want to increase max locks by database setting or make a copy on database level. I want to understand how I can copy with best performance and low usage memory in ABAP... Thank you.
