Hi can someone let me know if its possible to create linked service to lake database in Azure Data Factory?
I've googled it but there is not tangible information?
There is no direct way to connect to a lake database present in Azure Synapse Analytics (like connecting to dedicated SQL pool). The lake databases in Azure synapse analytics store their data inside an azure data lake storage. This is done with the help of the linked service to the data lake storage account. By default, the data lake account created at the time of creation of synapse workspace will be used to store all the data of lake database.
When you choose Lake Database -> <your_database> -> open, then you can see in the storage settings about the details of linked service and the input folder where it will be stored.
So, you can simply create a linked service to the data lake storage account which was used to store the data of lake database in azure synapse. Refer to this official Microsoft documentation to understand about the Lake Databases.

Is there any possibility to take the backup of mongodb which hosted in Azure-vm(ubuntu18.04)from azure services?
I already have the script to take the backup of mongodb and send it to azure blob storage.
But I don't want to take the backup in azure-VM server and send it to blob.
Instead is there any other way to take backup from any azure services?
I analyzed and found that we can migrate the database to azure cosmos and take backup. I can't afford to pay cost for that. So i want to know any other way to take backup directly from azure
I need to copy one year of historical data from Azure data lake storage to Azure PostgreSQL database. 1 day data = 65 GB. How can I load that much data in less time
You can try Azure Data Factory. ADF has connectors for both ADLS and Azure Database for PostgreSQL. Refer to below metrics based on network bandwidth and data size for copy activity in ADF:
Copy activity performance and scalability guide
Below are some sample articles to use ADLS and Azure Postgres with ADF:
Copy and transform data in Azure Data Lake Storage Gen2 using Azure Data Factory or Azure Synapse Analytics
Copy and transform data in Azure Database for PostgreSQL using Azure Data Factory or Synapse Analytics
I know Data Export Service has a SQL storage target where as Export to Data Lake is Gen2 but seeing that Dataverse (aka Common Data Service) is structured data, I can't see why you'd use Export to Data Lake option in Powerapps, as Gen2 is for un-structured and semi-structured data!
Am I missing something here? Could they both be used e.g. Gen2 to store images data?
Data Export service is v1 used to replicate the Dynamics CRM online data to Azure SQL or Azure IaaS SQL server in near real time.
Export to Datalake is similar to v2, for the same replication purpose with new trick :) snapshot is advantage here.
There is a v3 coming, almost similar to v2 but additionally with Azure synapse linkage.
These are happening very fast and not sure how community is going to adapt.
We have an app hosted on Azure using mongoDB (running on a VM) and Azure SQL dbs. The idea is to build a basic data analysis pipeline to "join" the data between both these DBs and visually display the same using power BI.
For instance we have a "user" table in SQL with a unique "id" and a "data" table in mongo that has a reference of "id" + other tables in SQL that have reference of 'id'. So we wish to analyse the contents of data based on user and possibly join that further with other tables as needed.
Is azure data lake + power BI enough to implement this case? Or we need azure data analytics or azure synapse for this?
Azure Data Lake (ADL) and Power BI on its own is not going to be able to build a pipeline, ADL it is just a storage area and Power BI is a very much a lightweight ETL tool limited by features and capacity.
It would be highly recommended that you have some better compute power behind it using, as you mentioned Azure Synapse. That will be able to have a defined pipeline to orchestrate data movement into the data lake, then do the processing to transform the data.
Power BI on it own will not be able to do this, as you will still be limited by the Dataflow and Dataset size of 1GB if running Pro. Azure Synapse does contain Azure Data Factory Pipelines, Apache Spark and Azure SQL Data Warehouse so you can choose between Spark and SQL for your data transformational steps as both will connect to the Data Lake.
Note: Azure Data Lake Analytics (ADLA) (and USQL) is not a major focus for MS, and never widely used. Azure Databricks and Azure Synapse with Spark has replaced ADLA in all of the modern data pipeline and architectures examples for MS.
i am trying to migrate object storage from ibm cloud's one account to another account.I am trying to use rclone but it is very confusing.Please some one help me with proper steps.
You can use IBM App Connect to move all data from a partner cloud storage system like Amazon S3 to Cloud Object Storage or in the same cloud between Cloud storages
Suppose your organization needs to move all data from a partner cloud
storage system like Amazon S3 to Cloud Object Storage. This task
involves the transfer of a large amount of data. By using a batch
retrieve operation in App Connect, you can extract all the files from
an Amazon S3 bucket and upload them to a Cloud Object Storage bucket.
Before you start: This article assumes that you’ve created accounts
for Amazon S3 and Cloud Object Storage.
Follow the instructions in this post and just replace Amazon S3 instance with IBM Cloud Object storage from where you want to migrate the data from
