issue: #34123 Benchmark case: The benchmark run the go benchmark function `BenchmarkDeltalogFormat` which is put in the Files changed. It tests the performance of serializing and deserializing from two different data formats under a 10 million delete log dataset. Metrics: The benchmarks measure the average time taken per operation (ns/op), memory allocated per operation (MB/op), and the number of memory allocations per operation (allocs/op). | Test Name | Avg Time (ns/op) | Time Comparison | Memory Allocation (MB/op) | Memory Comparison | Allocation Count (allocs/op) | Allocation Comparison | |---------------------------------|------------------|-----------------|---------------------------|-------------------|------------------------------|------------------------| | one_string_format_reader | 2,781,990,000 | Baseline | 2,422 | Baseline | 20,336,539 | Baseline | | pk_ts_separate_format_reader | 480,682,639 | -82.72% | 1,765 | -27.14% | 20,396,958 | +0.30% | | one_string_format_writer | 5,483,436,041 | Baseline | 13,900 | Baseline | 70,057,473 | Baseline | | pk_and_ts_separate_format_writer| 798,591,584 | -85.43% | 2,178 | -84.34% | 30,270,488 | -56.78% | Both read and write operations show significant improvements in both speed and memory allocation.
