IMPLEMENTATION_OFPackage

PERTAIN_TOProblem

it uploads the file successfully, but just dumps the file on the "root" directory in Vercel blob storage — upload an image for example via the Payload admin upload feature. Tension: This makes my blob storage explorer in Vercel look very messy. Outcome: I would therefore very much like a folder for each project.

PERTAIN_TOSolution

You can use the `prefix` field to set a sub-directory. — vercelBlobStorage({ enabled: true, collections: { media: { prefix: 'cms_images', }, }, token: process.env.BLOB_READ_WRITE_TOKEN, }). Tension: As of now, there's no fix for this. Outcome: You can manually handle uploads as shown here.

PERTAIN_TOSolution

Use upload(`content/temp/${file.name}`, file, { handleUploadUrl, clientPayload }) and return the pathname settings from onBeforeGenerateToken()

PERTAIN_TOSolution

Create a POST request to generate a signedUrl on the server — Send that URL to the client and POST the upload form with image to the S3 bucket. Tension: bypassing the server. Outcome: With that url you can POST directly to S3.

PERTAIN_TOProblem

The job is taking approximately 4 hours to complete — AWS Glue job that processes thousands of small JSON files from S3. Tension: which is unacceptable for our use case. Outcome: The job processes the files but is extremely slow.

PERTAIN_TOSolution

bypassing Spark's native S3 file reading and using Boto3 to read files in parallel — This reduced my processing time from 4 hours to 20 minutes. Tension: Spark's native S3 file reading.

PERTAIN_TOProblem

using pre-signed-url, I can't check the file size of each part — multipart upload in my application. Tension: all the options I thought do not appear to be good one. Outcome: I really would not like to get the file in any endpoint of my application.

PERTAIN_TOSolution

JavaScript can access the `size` from the File object — using a UI for the upload. Tension: I really would not like to get the file in any endpoint of my application. Outcome: Use this value to populate the `content-length` header value.

PERTAIN_TOProblem

fails with a 403 Forbidden error and the message CannotVerifyCopySource — I'm trying to copy a CSV file from an AWS S3 bucket to Azure Blob Storage using AzCopy. Tension: The command executes but fails.

PERTAIN_TOSolution

As of 5/8/2025, the only known workaround is to download the file and upload it using LocalBlob. Tension: the only known workaround. Outcome: download the file and upload it using LocalBlob.

PERTAIN_TOSolution

view an object's S3 Intelligent Tiering access tier through an S3 Inventory report — Configure S3 Inventory. Tension: This can be enabled on a bucket or prefix level and is generated on a daily or weekly frequency. Outcome: download the file from the S3 Inventory output location and parse if locally or query it via Athena.

PERTAIN_TOProblem

TypeError: 'S3File' object cannot be converted to 'PyString' — when I set `partition_by='b'` using the following code. Outcome: How do I write polars dataframe to S3 with `partition_by='b'`?

PERTAIN_TOSolution

df.write_parquet("s3://my-bucket-name/my/path/to/file", partition_by='b') — As I understand here is the line of the code which causes an error. Outcome: So try to pass python string explicitly.

PERTAIN_TOProblem

Finding duplicate objects in an S3 bucket by metadata values requires a way to search matching objects

PERTAIN_TOSolution

Use S3 Metadata tables and query e_tag with Athena or another Iceberg-compatible tool to locate duplicate objects

PERTAIN_TOProblem

Old backup objects/versions in an S3 bucket are not being deleted by the lifecycle rule even though the script and visible object listing suggest only the expected recent backups remain.

PERTAIN_TOSolution

Verify each object version’s Object Lock retention (mode and expiration) using `get-object-retention`, then adjust the lifecycle rule window to be compatible with the retention period or wait until the retention expires (or release/override retention per Object Lock settings).

PERTAIN_TOProblem

it creates a single table "mongodb_attempts" — I've created a crawler with data source `.../hist/mongodb/mongodb_attempts/`. Tension: instead of creating a table for each attempts_YYYYMMDD.

PERTAIN_TOSolution

Choose the option `Create single schema for each S3 path`. — This can be done via S3 schema grouping. Tension: define the depth level. Outcome: In your case I believe table level would be 5.

PERTAIN_TOProblem

All of the put/upload functions want a set content length. Tension: Building the zip locally is not an option, because the end size of the zip can be tens of GB. Outcome: I essentially need a zip "placeholder" on S3 that I can stream to.

PERTAIN_TOProblem

The HTTP request cannot be executed: The peer resets the connection. — When I try to upload files to S3 from storage via an application deployed on the stand. Tension: Everything is working locally. All files is uploading without errors. Outcome: com.amazonaws.SdkClientException exception.

PERTAIN_TOSolution

update to AWS SDK for Java V2 ASAP — when using V2 to upload larger files. Tension: The Amazon S3 Transfer Manager API can certainly handle larger files. Outcome: use software.amazon.awssdk.transfer.s3.S3TransferManager API.

PERTAIN_TOProblem

nothing is getting written to the s3 bucket — trying to use ytdl-core in an AWS lambda function to upload an .mp4 of a youtube video to an S3 bucket. Tension: I cannot get ytdl to create a stream with any data in it. Outcome: Right now nothing is getting pushed to the buffer or the s3 bucket.

PERTAIN_TOSolution

The package has been depreciated. — use ytdl-core in an AWS lambda function to upload an .mp4 of a youtube video to an S3 bucket. Tension: I can't seem to get anything to work. Outcome: Use this instead - distubejs/ytdl-core.

PERTAIN_TOProblem

Texts written in this way of course stop displaying images after this time — After adding an embedded/inline image in Trix, a temporary url is saved in the body content.

PERTAIN_TOSolution

with url from rails_blob_url, which would be converted to a temporary URL each time the text is loaded from the database — with ActiveStorage urls_expire_in 30 min option. Tension: or is this not the right way at all.

PERTAIN_TOProblem

understanding the event payload structure passed by EventBridge to my .NET Lambda function — an AWS serverless application using .NET, where I'm configuring a Lambda function to be triggered by S3 events routed through AWS EventBridge. Tension: I'm specifically seeking guidance on understanding the event payload structure passed by EventBridge to my .NET Lambda function and how to process it effectively. Outcome: How can I deserialize and process the event payload within my .NET Lambda function to perform actions based on the S3 event that triggered it?

PERTAIN_TOSolution

To handle S3 EventBridge events, you need to add the `Amazon.Lambda.CloudWatchEvents` NuGet package to the project. — The Lambda function will look like this. Tension: If you are wondering why the package is called `Amazon.Lambda.CloudWatchEvents`, it is because CloudWatch Events is the predecessor of EventBridge. Outcome: Run `dotnet add package Amazon.Lambda.CloudWatchEvents`.

PERTAIN_TOProblem

I want to use only those to run another transformation pipeline which flattens the json structure. — at the end of the analysis bucket I get some json files called result_.json. Tension: I tried to get the list of all the ids and then creating one format key like f'{projects_path}project_{project_id}/result_{project_id}.json' but that did not work.

PERTAIN_TOSolution

You can split the key of each file at some character (for example `/`). — in pseudocode (assuming you have boto3 setup in the environment you are executing your python code):. Tension: This is the most naive approach, and better solutions can be implemented specific to your task. Outcome: list the items in the bucket then just filter a list of strings with regex.

PERTAIN_TOProblem

it takes a lot of time — read these files in my pyspark job using `spark.read.parquet(*keys)`. Tension: The reading alone is take in neighborhood of 1hr for a 40CPU cluster. Outcome: All these parquet files have same schema.

PERTAIN_TOProblem

Timeout waiting for connection from pool. Tension: Task 4217 in stage 4.0 failed 4 times. Outcome: Job aborted due to stage failure.

PERTAIN_TOSolution

The default value in EMR 7.0.0 is 50. Tension: the number of incoming requests to S3 exceeds the capacity of the connection pool. Outcome: `--conf spark.sql.catalog.{ice_catalog}.http-client.apache.max-connections=3000`.

PERTAIN_TOSolution

Make sure you have the region in your s3 location — CREATE EXTERNAL DATA SOURCE s3_ds. Tension: did not have the region in the URL.

PERTAIN_TOProblem

If I read the documentation correctly, this should work. — I have 2 AWS Accounts. Tension: Account B has users, that would like to be able to see those documents in `my_awesome_files`.

PERTAIN_TOSolution

Create a helper to get the assumed role credentials — Using `CredentialProvider::memoize` cache's the credentials so if you need them elsewhere in your app. Tension: your app doesn't have to get new credentials every time. Outcome: Remember to register this Service Provider in your `app.php` config.

PERTAIN_TOProblem

I’ve successfully configured Weaviate to store both the image embeddings and the images themselves — using Weaviate as a vector database to store and search for images based on their embeddings. Tension: I’m interested in optimizing this setup to conserve storage space and streamline the search process. Outcome: I couldn’t find a way to disable the storage of image files in Weaviate.

PERTAIN_TOSolution

It has a `/vectors` endpoint that receives a POST request with body `{id: TEMP_FILENAME, image: BASE64_IMG}` — Here is a custom javascript function to produce a vector of an image (picture). Tension: Create a schema. Notice that here you don't specify a `vectorizer`. Outcome: followed the custom vector API tutorial.

PERTAIN_TOProblem

Minio upload with a stream blocks until the file stream is closed

PERTAIN_TOSolution

Use a FileStream in a using block and pass it to PutObjectAsync

PERTAIN_TOProblem

s3fs: unable to access MOUNTPOINT iotbigdatarawfilesft-lit:/InputFiles/OCOMC-mnt/: No such file or directory — I am trying to mount S3 sub-directories, using the following command:. Tension: I have tried a lot of fixes but with no success, actually I don't know what's the issue. Outcome: Check if your bucket name is correct it should be something like this and also check if path "/opt/SP/users/oracle/data/input/" also exist.

PERTAIN_TOSolution

Check if your bucket name is correct — "/opt/SP/users/oracle/data/input/" also exist. Tension: I have tried a lot of fixes but with no success. Outcome: also check if path "/opt/SP/users/oracle/data/input/" also exist.
