Fields

id: u64

max_frame_no: u64

Max frame number that this transaction can read

max_offset: u64

db_size: u32

current: Arc<CurrentSegment<F>>

created_at: Instant

conn_id: u64

pages_read: usize

number of pages read by this transaction. This is used to determine whether a write lock will be re-acquired.
