Fields

otlp_grpc_addr: String

rest_api_addr: String

rest_api_socket: Option<String>

data_dir: String

wal_dir: String

storage: StorageBackend

query_shards: Vec<String>

When non-empty, this process runs as a stateless query tier: reads are served by a FanoutStore that scatter-gathers across these shard base URLs (http://shard-0:7701,...) instead of a local engine. Set via TAEL_QUERY_SHARDS. See docs/tael-server-scaling-ha.md §3.

wal_standbys: Vec<String>

Standby base URLs this node ships its WAL to as a leader (http://standby-1:7701,...). Set via TAEL_WAL_STANDBYS. Only honored by the tael-backend engine. See §5.1.

wal_required_acks: Option<usize>

How many standbys must ack a write before it returns. None = all (fully synchronous); Some(0) = async best-effort. Set via TAEL_WAL_REQUIRED_ACKS.

cluster: Option<ClusterSettings>

Cluster coordination (chitchat) for automatic leader election + epoch fencing of WAL replication. Some when TAEL_CLUSTER_LISTEN is set. See docs/tael-server-scaling-ha.md §5.1.

object_store: ObjectStoreConfig

Where the cold tier and blob store keep their objects. Defaults to local filesystem (unchanged single-binary behavior); GCS is opt-in and needs the cloud build feature.

comments: CommentsConfig

Where trace comments are stored. Defaults to the local JSONL file; Postgres (Cloud SQL) is opt-in and needs the cloud build feature.
