Module metrics 

Streaming query lifecycle types: identifiers, states, configuration, errors, and metrics.

These types are always available (not gated behind jit) so that configuration, error handling, and metrics aggregation can be used without pulling in Cranelift.

Structs

QueryConfig

Configuration for a streaming query.

QueryId

Unique identifier for a streaming query, derived from hashing the SQL text.

QueryMetadata

Metadata about how a query was compiled.

QueryMetrics

Aggregated runtime metrics for a streaming query.

Enums

QueryError

Errors from streaming query operations.

QueryState

Lifecycle state of a StreamingQuery (requires jit feature).

StateStoreConfig

State store backend configuration (kept minimal for now).

SubmitResult

Result of submitting an event row to a streaming query.
