    Properties

    client_heap: bigint | null

    Total available bytes for allocation on the [Client]. This is only available if trace-allocator is enabled.

    client_used: bigint | null

    Bytes allocated for use on the [Client]. This is only available if trace-allocator is enabled.

    cpu_time: number

    Wall-clock time spent processing requests on the [Server], in milliseconds (estimated). This does not properly account for the internal thread pool (which enables column-parallel processing of individual requests).

    cpu_time_epoch: number

    Milliseconds since internal CPU time accumulator was reset.

    heap_size: bigint

    Total available bytes for allocation on the [Server].

    timestamp: bigint | null

    Timestamp (POSIX) this request was made. This field may be omitted for wasm due to perspective-client lacking a dependency on wasm_bindgen.

    used_size: bigint

    Bytes allocated for use on the [Server].
