ExperimentalOptional Readonly ExperimentalcancelReadonly ExperimentalcreateOptional Readonly ExperimentalmaxIncludes the active request. Defaults to 16; there is no unbounded mode.
Optional Readonly ExperimentalstreamCross-request ordering contract. Defaults to none, which accepts every
request independently. strict declares that this session carries one
ordered batch stream and rejects a non-increasing sequence or a
non-contiguous rowOffset before the batch is transferred.
Optional Readonly ExperimentaltelemetryOptional observer for this session. Off by default. Every execute emits
one columnar-worker-operation span spanning enqueue through settlement,
and the ownership handoff it performs emits its own columnar-transfer
span, both bound to the input batch's identity.
Milliseconds a cancelled in-flight request may take to be acknowledged by the worker before the transport is retired. Defaults to 50. A cooperative operation that observes its signal acknowledges well inside the window and keeps the worker warm; a non-cooperative one is retired at the deadline.
