Cognite Data Fusion: Data extract enhancement request

It sounds like you are downloading an individual event by clicking the download button. I do see your pains on not having a way to download bulk data directly from fusion right in the UI; however, there are multiple other methods that one can leverage to explore data in CDF.

PowerBI would be a good option for someone not wishing to code.

Some code approaches:
I've tacked a similar problem by leveraging the Cognite Spark Data Source (some info in Cognite Docs) where you can execute sql to read the entirety of a particular resource type. The metadata is still in a similar format, but leveraging instructions here should flatten them out to columns. This approach would work best if you able to leverage databricks/pyspark. 

If you do not have access to databricks/pyspark a similar workflow could be accomplished using the python sdk. Where you can list all of a particular resource type, easily retrieve it as a pandas dataframe, and manipulate the code snippit below to flatten the metadata.

###importing pandas and cognite-sdk
cdf_df = c.events.list(limit=-1).to_pandas()
cdf_df = pd.concat([cdf_df.drop('metadata', axis=1), pd.json_normalize(cdf_df['metadata'])], axis=1)

How about enabling a better search and download capability with UI/UX in CDF?
