Summary
new metrics
While selecting the blocks with the highest depth
segments no longer processed one by one, multiple segments might be squashed into one unit for selection, if the number of blocks of these segments reaches the value of setting FUSE_OPT_KEY_BLOCK_PER_SEGMENT.
tweak(fix) the logic of
ReclusterMutator::segment_can_recluster
the segment will be a candidate for recluster, only if it does not consist of constant blocks(only), or the number of blocks does not reach the value of setting FUSE_OPT_KEY_BLOCK_PER_SEGMENT.
adjusted log messages for clarity and precision.
