Struct BigTableConfig 

pub struct BigTableConfig {
    pub endpoint: Option<String>,
    pub project_id: String,
    pub instance_name: String,
    pub table_name: String,
    pub connections: Option<usize>,
    pub rpc_timeout: Duration,
    pub cogs: Option<CostTrackerStreamConfig>,
}

Configuration for BigTableBackend.

Stores objects in Google Cloud Bigtable, a NoSQL wide-column database optimized for high-throughput, low-latency workloads with small objects. Authentication uses Application Default Credentials (ADC).

Note: The table must be pre-created with the following column families:

• fg: timestamp-based garbage collection (maxage=1s)
• fm: manual garbage collection (no GC policy)

Example

storage:
  type: bigtable
  project_id: my-project
  instance_name: objectstore
  table_name: objectstore

Fields

endpoint: Option<String>

Optional custom Bigtable endpoint.

Useful for testing with emulators. If None, uses the default Bigtable endpoint.

Default

None (uses default Bigtable endpoint)

Environment Variables

• OS__STORAGE__TYPE=bigtable
• OS__STORAGE__ENDPOINT=localhost:8086 (optional)

project_id: String

GCP project ID.

The Google project ID (not project number) containing the Bigtable instance.

Environment Variables

• OS__STORAGE__PROJECT_ID=my-project

instance_name: String

Bigtable instance name.

Environment Variables

• OS__STORAGE__INSTANCE_NAME=my-instance

table_name: String

Bigtable table name.

The table must exist before starting the server.

Environment Variables

• OS__STORAGE__TABLE_NAME=objectstore

connections: Option<usize>

Optional number of connections to maintain to Bigtable.

Default

None (defaults to 1)

Environment Variables

• OS__STORAGE__CONNECTIONS=16 (optional)

rpc_timeout: Duration

Timeout for an individual Bigtable RPC attempt.

Default

2s

Environment Variables

• OS__STORAGE__RPC_TIMEOUT=2s
• OS__STORAGE__HIGH_VOLUME__RPC_TIMEOUT=2s (tiered storage)

cogs: Option<CostTrackerStreamConfig>

Reports what this backend stores, for per-usecase cost attribution.

Default

None, which disables reporting for this backend.

Environment Variables

• OS__STORAGE__COGS__SHARED_RESOURCE_ID=bigtable_objectstore
• OS__STORAGE__COGS__SAMPLE_RATE=1.0 (optional)
