Connector Google Cloud Storage
The Google Cloud Storage Connector allows you to connect the Google Cloud Storage bucket with Meiro Integrations so that it can be used as a data source for the data workflow.
Google Cloud Storage provides unified object storage for live or archived data.
Requirements
To set up the configuration for the Google Cloud Storage Connector, you will need a Google Cloud Storage account. You can create your account here. If you have not used Google Cloud Storage before, we recommend you to check the official Google Cloud Storage documentation.
Features
Wildcard
Using *
(wildcard) at the end of an expression in a key field allows you to search for the necessary files in the bucket. For example: use MyFolder/*
to connect to all the files in the MyFolder
directory.
Data In/Data Out
Data In
N/A
Data Out
Your results will be saved in the Data Out bucket data/out/files
folder.
You can read more about the folder structure here.
Authorization
After creating the Google Cloud Storage connector, you will first need to authorize it to access your Google account.
Parameters
Bucket Name (required)
Provide a Google Cloud Storage bucket name. As all bucket names reside in a single Cloud Storage namespace. To find the bucket name go to your Google Cloud Storage account, go to the Storage section and the Browser.
You can read more about Google Cloud storage buckets here.
Search Key (required)
In order to search for the key prefix for the files from the Google Cloud Storage bucket, it is possible to use a * wildcard at the end. For example, if you would like to connect only the files from the folder myfolder
, please insert myfolder/*
.
Include Sub-folders (true/false)
By marking that field you will download the data from the bucket with all subfolders. This option is available only with the wildcard *
.
New Files Only (true/false)
Checking the New Files option enables you to load the data in incremental loads.
After the first run of the configuration in the incremental mode, the state.json
file of the Data Out bucket is showing properties like:
"last_downloaded_file_timestamp"
that is the timestamp of the last change in the Google Cloud Storage connector (seconds since Jan 01 1970 UTC)"files_modified_in_last_downloaded_file_timestamp"
that lists names of the processed files in the last Timestamp
Each time you run the configuration, Meiro Integrations is checking the values of these properties and downloads only the unprocessed files to the Data Out bucket.
Limit (required)
The Limit field describes the maximum number of files to download. If the key matches more files than chosen, only the oldest files will be downloaded.
