Hi, I asked about parquet format yesterday and I had great feedback about my problem (https://community.safe.com/s/feed/0D54Q00008VE8CZSA1)
Right now I have a bigger problem - but I think, I have too small knowledge on this topic.
I have to connect to azure blob storage (datalake) based on SAS auth, I have permission into SAS key like:
ss=bfqt
srt=sco
sp=rl
So, I can create a list and I can read files, also I have SignedResourceTypes like Container, Service, and Object.
With parameters like that I see db, I see parquet files, also I can download files via Chrome (link+SAS)
But if I want to get attributes (and only it, without download files, because data are too big) - I used this kind of parameters:
and I have empty results:
My question:
Is it possible to get only attribute per parquet file which is existing in azure?
Or downloading data is required?
What I have:
- SAS key, which I can "modify", but as I mentioned - I think, I have required permissions
- name container
- account name to SAS auth
What I want:
- aggregated by filename (like fme basename on new collumn) attributes from azure.
