Usage counters for an opt-in query memory domain.

Fields

domain_id: u64

Caller-supplied query-memory-domain identity.

active: bool

Whether the domain remains active for allocation.

active_members: u64

Number of stream members currently attached to the domain.

ceiling_bytes: u64

Immutable logical ceiling declared when this domain was created, in bytes.

allocation_limit_bytes: u64

Enforced live allocation limit in bytes, charged using aligned allocation sizes.

current_bytes: u64

Requested bytes in allocations still retained at this snapshot.

peak_bytes: u64

Largest observed sum of requested bytes in simultaneously retained allocations.

total_bytes: u64

Cumulative requested bytes across successful allocations, including allocations later released.

current_aligned_bytes: u64

Live allocation charge in bytes after alignment.

peak_aligned_bytes: u64

Largest observed live allocation charge in bytes after alignment.

total_allocations: u64

Cumulative count of successful allocations, including allocations later released.

current_allocations: u64

Number of allocations still retained at this snapshot.

peak_allocations: u64

Largest observed number of simultaneously retained allocations.

failed_allocation_count: u64

Number of allocation requests rejected by a limit or the upstream allocator.

largest_failed_allocation_bytes: u64

Largest failed allocation request in bytes; zero when no allocation failure was recorded.
