Is it possible to delete a blob using any settings in the Azure portal or via code in c#?
Let's say, I am creating log files and uploading it to a blob container. I would like to delete all the log files which are older than a week time.
Please see the Tasks option under Automation section.
you probably want to look into azure blob storage lifecycle management:
https://azure.microsoft.com/en-us/blog/azure-blob-storage-lifecycle-management-public-preview/
#savagepanda is right. Azure Blob Storage has support for lifecycle management.
Manage the Azure Blob storage lifecycle
Azure Blob storage lifecycle management offers a rich, rule-based
policy for GPv2 and Blob storage accounts. Use the policy to
transition your data to the appropriate access tiers or expire at the
end of the data's lifecycle.
The lifecycle management policy lets you:
Transition blobs to a cooler storage tier (hot to cool, hot to
archive, or cool to archive) to optimize for performance and cost
Delete blobs at the end of their lifecycles Define rules to be run
once per day at the storage account level Apply rules to containers or
a subset of blobs (using prefixes as filters)

I want to configure an azure lifecycle policy to containers such that the blobs are moved to cool tier after some specific time, but the blobs are inside dynamically created directory inside container, e.g
mycontainer/test-123/blob1.pdf;
mycontainer/test-98765/blob2.pdf;
mycontainer/test-qw9876/blob3.pdf
where "mycontainer/test-" remains same for all the blobs, but file names are dynamic, we need to apply the policy for the all blobs under the container "mycontainer/test-*".
Note: * values will be dynamically generated.
I tried to add the blobs in the container and move to cool tiers I'm getting result successfully without any dynamical creation
In your storage account -> use storage browser -> under blob container -> create container -> upload files directly in the container
After configuring an azure lifecycle policy to containers moving blobs to cool tier try to remove the character and update the rule
Here, blobs are moved to cool tier without any changes even after specific time

Unexpected links generated when creating a folder hierarchy in blob storage - Stack Overflow
I create service which uses few ADF pipelines, which will be responsible for processing of large amount of big files.
The main purpose is not to create azure services like database, azure storage account and pipelines on local developer account with 50Euro credit. The biggest drawback of such solution is size of processed file. Such big files could burn credit and blue CK such account.
Structure of a project looks like:
web-ui - API server - azure data factory with pipelines (unit used for processing and calculation files). In order to develop and debug such project everything should be configurable on local machine. Data factory with pipelines will use database information in order to process and create calculations on files
I looked for different approaches to deploy such projects with ADF pipelines, but there is no general solution for such structure. Is it possible to simulate and create local instance of pipeline on developer's machine?
Good day , I'm new in azure blob and don't know what kinds of experiments can be done with it, I have searched about it but still isn't clear to me. I'll be really gratefull if you can tell me about easy experiments that can be done in azure blob.
Blob storage stores unstructured data such as text, binary data, documents or media files.
Hope you meant the samples or the operations that can be done using azure blob when you say experiments.
You can do operations like uploading the files, downloading , listing etc. programmatically or through the UI.
You can above operations using languages such as .Net, Java,Python,JS..etc which you can find links in this documentation Azure Storage samples
But to access Azure Storage, you'll need an Azure subscription or free trial account. All access to Azure Storage takes place through a storage account. For this quickstart, create a storage account using the Azure portal.
Refer to Create a storage account
You can do above operations in portal directly .This sample blog can give you quick insights to perform them through portal.
A number of solutions exist for migrating existing data to Blob storage like AzCopy ,Azure datafactory etc
Introduction to Blob (object) storage - Azure Storage | Microsoft Docs
I'm looking to setup a Lifecycle Management rule in Azure Storage account to move blobs to an Archive storage account after X days.
When I go to create the rule, the only option is to Delete the blob:
In these docs, I see options like Move to cool storage, etc.:
How do I enable these options?
Setup:
ADLS Gen 2
Hierarchical Namespaces enabled
Standard performance / Hot access tier
RA-GRS replication
Aha! Selecting Append Blobs checkbox disables all options other than Delete the blob.
Append Blobs are not allowed to be moved to Cold / Archived storage using the current Lifecycle Management blade.
There has been numerous discussions related to storing images (or binary data) in the database or file system (Refer: Storing Images in DB - Yea or Nay?)
We have decided to use the file system for storing images and relevant image specific metadata in the database itself in the short term and migrate to an amazon s3 based data store in the future. Note: the data store will be used to store user pictures, photos from group meetings ...
Are there any off the shelf java based open source frameworks which provide an abstraction to handle storage and retrieval via http for the above data stores. We wouldn't want to write any code related to admin tasks like backups, purging, maintenance.
Jets3t - http://jets3t.s3.amazonaws.com/index.html
We've used this and it works like a charm for S3.
I'm not sure I understand if you are looking for a framework that will work for both file-system storage and S3, but as unique as S3 is, I'm not sure that such a thing would exist. Obviously with S3, backups and maintenance are handled for you.
