Test summary
According to the test results, the memory usage of the optimized connector is relatively stable when the read size of each batch of the source segment remains unchanged, and the impact of the write batch size on memory usage is small, and it also reduces the time due to insufficient memory. The problem of slow data processing caused by high CPU usage caused by GC.
