## Google Cloud Storage Extension
|
|
|
|
This extension allows you to do 2 things:
|
|
* [Ingest data](#reading-data-from-google-cloud-storage) from files stored in Google Cloud Storage.
|
|
* Write segments to [deep storage](#deep-storage) in S3.
|
|
|
|
To use this Apache Druid extension, make sure to [include](../../development/extensions.md#loading-extensions) `druid-google-extensions` extension.
|
|
|
|
### Required Configuration
|
|
|
|
To configure connectivity to google cloud, run druid processes with `GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_keyfile` in the environment.
|
|
|
|
### Reading data from Google Cloud Storage
|
|
|
|
The [Google Cloud Storage input source](../../ingestion/native-batch.md#google-cloud-storage-input-source) is supported by the [Parallel task](../../ingestion/native-batch.md#parallel-task)
|
|
to read objects directly from Google Cloud Storage. If you use the [Hadoop task](../../ingestion/hadoop.md),
|
|
you can read data from Google Cloud Storage by specifying the paths in your [`inputSpec`](../../ingestion/hadoop.md#inputspec).
|
|
|
|
Objects can also be read directly from Google Cloud Storage via the [StaticGoogleBlobStoreFirehose](../../ingestion/native-batch.md#staticgoogleblobstorefirehose)
|
|
|
|
### Deep Storage
|
|
|
|
Deep storage can be written to Google Cloud Storage either via this extension or the [druid-hdfs-storage extension](../extensions-core/hdfs.md).
|
|
|
|
#### Configuration
|
|
|
|
To configure connectivity to google cloud, run druid processes with `GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_keyfile` in the environment.
