### Purpose Current Blob Bunch will sort merge blob files EACH TIME adding a new blob. This will cause significant efficiency decrease. We should check blob file ranges after adding all files. Sort merge them only once. Result: | Number of Blob files | Before: merge on every `add` (ms) | After: merge once in `finish` (ms) | Speedup | |---:|---:|---:|---:| | 10 | 0.042 | 0.011 | 3.8× | | 100 | 3.482 | 0.104 | 33.6× | | 500 | 83.519 | 0.495 | 168.8× | | 1,000 | 330.831 | 1.003 | 329.9× | | 2,000 | 1,319.063 | 1.959 | 673.5× | ### Tests Unit Test -- This is an automated message from the Apache Git Service.
