+ The above show the block distribution percentage according to the number of rows in each block. In the above example, `_block_dist: 3483 ||||||||||||||||| 1 (20.00%)` means there is one block whose rows is between 3,483 and 3,681. `_block_dist: 3881 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 4 (80.00%)` means there are 4 blocks whose rows is between 3,881 and 4,096. The number of blocks whose rows fall in other range is zero. ## SHOW TAGS -- GitLab
