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_TORootCause

the tasks with no data will not create the files — Let's say I a pyspark dataframe having 20 partitions, out of that only 4 has data in it and 16 are empty. Outcome: 4 files will be created.

PERTAIN_TOProblem

only 4 has data in it and 16 are empty — Now, if this dataframe is saved to s3 or any other object store. Tension: how many part files will be created? Outcome: tasks with no data will not create the files.

PERTAIN_TOSolution

what kind of setting we have (AQE Enabled, maxRecordsPerFile configuration, etc..) — for the part files again. Tension: it really depends on how the shuffling is done. Outcome: it could be anywhere between 1 to max no.of records present per col5 value.

PERTAIN_TOSolution

df.repartition(5).partitionBy("col5").write.format("parquet").save("s3_path_2") — Scenario 2. Tension: the data is re-distributed amongst 5 partitions. Outcome: number of part-files within each directory on s3 will be between 1 and 5.

PERTAIN_TOProblem

Unable to inject and configure Aws\S3\S3Client as a Symfony service

PERTAIN_TOSolution

Use a Flysystem storage abstraction instead of injecting S3Client directly

PERTAIN_TOSolution

I made a proxy object — using the magic method `__call` in order to forward any method call towards to actual S3. Tension: I failed. Outcome: Then upon services.yaml you can do.

PERTAIN_TOSolution

Be sure to print the bucket name before calling the SDK — before calling the SDK. Tension: to be sure that 'the resource' to which access is denied is as expected. Outcome: the AWS error message is therefore correct.

PERTAIN_TOProblem

The bucket you are attempting to access must be addressed using the specified endpoint. Tension: Status Code: 301.

PERTAIN_TOSolution

Please modify to this : — S3Client.builder(). Tension: region(Region.EU_CENTRAL_1). Outcome: region(Region.of("eu-west-1")) // Use the region obtained from the command.

PERTAIN_TOProblem

I need to access certain S3 buckets programmatically using IAM Roles Anywhere — working on a Spring Boot backend service. Tension: I’m unsure how to use it to create IAM Roles Anywhere sessions and authenticate to access S3.

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_TOProblem

is not authorized to perform: s3:ListBucket on resource. Tension: I am assuming only s3:GetObject is needed for code. Outcome: What and why there is listing?

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

Uploading to LocalStack S3 from a Quarkus app fails with an UnknownHostException when interacting with the configured S3 endpoint.

PERTAIN_TORootCause

S3 does not technically have a directory or folder structure — Creating a folder from the console creates a 0-byte object with the name of their directory. Tension: a folder from the console creates a 0-byte object with the name of their directory. Outcome: creating an empty folder called `foo` actually creates an object with the key (name) `foo/`.

PERTAIN_TOProblem

Metadata: {} — when I try to view the metadata via `HeadObjectCommand` on the object in the bucket. Tension: `x-amz-meta-author` is nowhere to be found. Outcome: Adding `x-amz-meta-author` to the headers for the PUT request allowed the data to be available in the `HeadObjectCommand`.

PERTAIN_TOSolution

Adding `x-amz-meta-author` to the headers for the PUT request allowed the data to be available in the `HeadObjectCommand` — fetch(signedURL, { method: 'PUT', headers: {. Tension: `x-amz-meta-author` is nowhere to be found. Outcome: Metadata: { author: 'John Doe' }.

PERTAIN_TOProblem

There is no official numbers provided by AWS. — decide between Python jobs and spark jobs. Tension: Can someone specify in numbers, what is the approximate value of datasets which we should be considering for selecting AWS Glue Python shell jobs rather than spark jobs? Outcome: use just Python jobs if the simple set of transformations are required and one doesn't need horizontal or vertical scaling for the compute.

PERTAIN_TOSolution

If your job is simple and can be solved using vanilla python, you should choose that. — AWS Glue ETL job to update data stored in S3 Objects to an existing table in DDB. Tension: There is no official numbers provided by AWS. Outcome: Also consider using packages i.e. Pandas, PyArrow etc. for performance improvement.

PERTAIN_TOProblem

facing throttling issues (503 errors) — writing to S3, and facing throttling issues (503 errors). Tension: our ingestion service still encounters 503 errors. Outcome: the files are showing right under my bucket at the root level.

PERTAIN_TOSolution

make sure that the `write.object-storage.enabled` property is set to true — This will make sure the objects are distributed across the prefixes.

PERTAIN_TOSolution

The data is compacted periodically — This applies both to the Iceberg metadata that's stored in Avro, and the data files itself. Tension: This will combine small manifests into bigger ones that will reduce the number of requests when reading.

PERTAIN_TOSolution

you have to disable the dev service — make sure to set this in your `application.properties` file. Tension: By default it is set to true. Outcome: quarkus.s3.devservices.enabled=false.

PERTAIN_TOSolution

Set quarkus.s3.endpoint-override=https://s3.amazonaws.com for local machine testing

PERTAIN_TOProblem

Outcome: do not use the endpoint `http://localhost:4566`.

PERTAIN_TOSolution

use the standard formate endpoint i.e : `http://s3.localhost.localstack.cloud:4566` — In case of localstack. Tension: it resolve using public DNS thus it either needs internet connection or you will need to make host entries. Outcome: you can also create network alias for your localstack container.

PERTAIN_TOProblem

when I test the Lambda function using the S3-put option. Outcome: This is not the expected result.

PERTAIN_TOProblem

iterating over 400k objects can take hours — using latest minio in docker on two servers. Tension: Sometimes it works fine. Outcome: How to speed it up?

PERTAIN_TOSolution

Maybe use a DB to keep a file key list. — Bucket contains around 400k objects, ~70 GB. Tension: get all keys in bucket. Outcome: avoid listObject on minio.

PERTAIN_TOSolution

you should put a txt file extension for the key — This AWS S3 Java V2 code works:. Tension: Your code looks ok; however, you should put a txt file extension for the key. Outcome: You should also debug your S3 Service Client to ensure it's fine.

PERTAIN_TOProblem

there is no option for "key" in the method I'm using , only "prefix" — rollback an S3 object to a specific version. Tension: in this example i will end up delete all versions of objects named "questions copy". So as you see, I had to filter in python, which seems less efficient.

PERTAIN_TOSolution

it is necessary to use `.object_versions` (or `list_object_versions()` for client calls) — since your code is written to only roll-back a single object. Tension: it's not really possible to reduce the number of API calls to AWS. Outcome: An alternative approach that could be considered 'more efficient' would be to copy the desired previous version to the same Key.

PERTAIN_TOProblem

Header 'x-amz-tagging-directive' with value 'COPY' not implemented — when I'm trying to copy the object. Tension: I tried to remove the header after creating an instance of `CopyObjectRequest`, but there is no header with similar name. Outcome: you need to manually do `GetObject` & then `PutObject` in order to copy the object across.

PERTAIN_TOSolution

you need to manually do `GetObject` & then `PutObject` — until CloudFlare support this header. Tension: CloudFlare support this header. Outcome: in order to copy the object across.

PERTAIN_TOSolution

override the copy method, and use your own marshaller — inherit the AmazonS3Client class. Tension: your operations will succeed, although the tags behavior will not match the one you would expect with S3. Outcome: your operations will succeed, although the tags behavior will not match the one you would expect with S3.

PERTAIN_TOSolution

I have considered using decodeURIComponent to convert the + back to spaces — const key = decodeURIComponent(event.Records[0].s3.object.key);. Tension: I'm unsure if this is a reliable solution, or if I'm supposed to handle these keys differently. Outcome: convert the + back to spaces.

PERTAIN_TOSolution

Use the AWS SDK to call AssumeRole, then pass the returned temporary credentials to S3Client

PERTAIN_TOProblem

Unable to parse request (not well-formed (invalid token): line 1, column 0), invalid XML received — using node.js to upload image to my s3 bucket on my local environment using localstack. Tension: This issue stems from using `Virtual-Hosted` style requests against LocalStack when using `localhost` as the endpoint. Outcome: the simplest would be to use `s3ForcePathStyle` for your client.

PERTAIN_TOProblem

the value is nowhere to be seen — I'm trying to create a powershell script to get the Metadata Key/Value pair for a set of s3 files. Tension: I have no problem getting the key. Outcome: This will work:.

PERTAIN_TOSolution

This will work. Outcome: $buildId = $fileDetail["x-amz-meta-build-id"].

PERTAIN_TOProblem

I want to use S3 Lifecycle to remove non-current version object. Tension: There is no rule apply to `hello.tar`. Outcome: The lifecycle rule functioned correctly, but there was an issue with the UI.

PERTAIN_TOSolution

The applied rule hadn't been displayed in the Management Configuration section. — from the object screen. Tension: the "Noncurrent versions actions" rule cannot be checked from the S3 object. Outcome: The description of the "Expiration date" states "The object will be made noncurrent and generate a delete marker on this date.".

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

Creating a new folder in an existing bucket displays this message at the top of the AWS S3 Console page every time. Tension: I can't seem to find any answers as to why this is displayed, perhaps its just default no matter the policy setup? Outcome: Just confirmed that the new user interface of S3 bucket now shows this message when creating a folder!

PERTAIN_TOSolution

upload an empty folder and specify the following settings in the upload configuration. — If your bucket policy prevents uploading objects to this bucket without tags, metadata, or access control list (ACL) grantees. Tension: you can't create a folder by using the following procedure. Outcome: Instead, upload an empty folder and specify the following settings in the upload configuration.
