Import recipe into Google Cloud Data Fusion pipeline - google-cloud-data-fusion

Is it possible to import a recipe exported from dataprep into a pipeline in Data Fusion?

No unfortunately they are currently not compatible and you cannot export a recipe from Cloud Dataprep (Wrangler) and import to Cloud Data Fusion (Wrangler). Two distinct engines/services, Cloud Dataprep based on Trifacta and Cloud Data Fusion from OSS CDAP

What's the difference between using Data Export Service and Export to Data Lake, regarding dataverse replication?

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.

Data analytics (join mongoDB and SQL data) through Azure Data Lake and power BI

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.

How to migrate object storage from one instance to another in IBM cloud?

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

Triggering a Dataflow job when new files are added to Cloud Storage

I'd like to trigger a Dataflow job when new files are added to a Storage bucket in order to process and add new data into a BigQuery table. I see that Cloud Functions can be triggered by changes in the bucket, but I haven't found a way to start a Dataflow job using the gcloud node.js library.
Is there a way to do this using Cloud Functions or is there an alternative way of achieving the desired result (inserting new data to BigQuery when files are added to a Storage bucket)?
This is supported in Apache Beam starting with 2.2. See Watching for new files matching a filepattern in Apache Beam.
Maybe this post would help on how to trigger Dataflow pipelines from App Engine or Cloud Functions?
