Storage Settings

Tune performance, spread data across locations, and set the default location for your data.

Set Default Storage

You can configure a default storage bucket for any table in your Hydrolix cluster. When you assign a default storage bucket for a table, new data ingested into that table automatically uses that storage bucket, unless otherwise specified.

Set Default Storage for a Cluster

Hydrolix also provides the ability to set a bucket used as the default bucket for all tables that do not specify a default bucket. Use settings.is_default in your storage configuration to assign a default storage bucket in a Hydrolix cluster:

"storage" : {
	"name": "hdx_primary",
	"description": "The initial bucket that comes up with the hdx cluster",
	"org": "<example org>"
	"settings": {
		"bucket_name": "<example name>",
		"bucket_path": "/",
		"region": "<example region>",
		"cloud": "<vendor",
		"endpoint": "<endpoint URL>",
		"is_default": true
	}
}

If you do not specify a default storage bucket, but your cluster only contains a single storage bucket, Hydrolix automatically assigns that single bucket as the default.

Set Default Storage for a Table

This snippet assigns a default storage bucket to a table.

"example_table": {
  "name": "<example_table_name>",
  ...
  "storage_map": {
    "default_storage_id": "<example_storage_id>",
  }
}
