Azure Blob Storage

Runs in

The Phloem cloud — nothing to install

Turns CSV, JSON and Parquet files in your Azure storage containers into tables you and Hamming can query, listed in Trace.

#What Phloem reads

• CSV, JSON and Parquet files, including gzipped .csv.gz and .json.gz, in the containers you pick
• Files are grouped into tables by path and format, with partition folders detected and column names and types sampled
• The tables you keep, with their columns, listed in Trace for Hamming and SQL autocomplete

Files are read in place. Phloem never writes to your storage account.

#What you need

• A storage account, and one of: its connection string, its account name and key, or a SAS token
• A credential that can list the account's containers and read their blobs

#Connect

1. In the console, open Connectors, choose Add connector, then Azure Blob Storage.
2. On Azure Credentials, choose an Authentication Method:
   • Connection String — paste it into Connection String (Azure Portal › Storage Account › Access Keys).
   • Account Name & Key — enter Storage Account Name and Account Key.
   • SAS Token — enter Storage Account Name and SAS Token, including the leading ?.
3. On Testing Credentials, Phloem lists the account's containers.
4. On Select Containers, pick the containers to connect.
5. On Discovered Tables, review the proposed tables. Each is a File Pattern (e.g. raw/events/**/*.parquet) matching files with the same layout. Edit a table's Table Name, File Pattern or Description, or turn it off.
6. On Save Connection, name the connector and save it.

#Notes

• Discovery samples each folder instead of listing every file. A table it is unsure of starts turned off, so check the patterns before saving.
• Files and folders starting with _ or ., and tmp, temp and log folders, are skipped.
