Struct CounterMetrics

pub struct CounterMetrics {
    pub call_atomic_op: u64,
    pub call_clear: u64,
    pub call_clear_range: u64,
    pub call_get: u64,
    pub keys_values_fetched: u64,
    pub bytes_read: u64,
    pub call_set: u64,
    pub bytes_written: u64,
}

CounterMetrics is used in two contexts within the metrics system:

• As current metrics: tracking operations for the current transaction attempt
• As total metrics: aggregating operations across all transaction attempts including retries

Each counter is incremented when the corresponding operation is performed, allowing for detailed analysis of transaction behavior and performance characteristics.

Fields

call_atomic_op: u64

Number of atomic operations performed (add, and, or, etc.)

call_clear: u64

Number of key clear operations performed

call_clear_range: u64

Number of range clear operations performed

call_get: u64

Number of get operations performed

keys_values_fetched: u64

Total number of key-value pairs fetched across all read operations

bytes_read: u64

Total number of bytes read from the database

call_set: u64

Number of set operations performed

bytes_written: u64

Total number of bytes written to the database

Implementations

impl CounterMetrics

pub fn increment(&mut self, fdb_command: &FdbCommand)

Increments the metrics for a given FDB command.

This method updates the metrics counters based on the type of FDB command.

Arguments

• fdb_command - The FDB command to increment metrics for
