hi @Juanes ,    great!   So, let's assume I have a 500GB table and that table was created with 240 tablets, would that value be within the recommended range?   other point!   I'm using the following calculates as an example:   DATA_SIZE = (value taken from the graph "total_kudu_on_disk_size_across_kudu_replicas") NUM_REPLICAS = RF * Total Tablets (value taken from the ksck command) TABLET_SIZE = DATA_SIZE / NUM_REPLICAS   DATA_SIZE = 147G (converted to bytes, getting "157840048128") NUM_REPLICAS = 3 * 240 = 360   Name | RF | State | Total Tablets | Healthy | Recovering | Underreplicated | not available impala::DATABASE01.TABLE01 | 3 | HEALTHY | 240 | 240 | 0 | 0 | 0   TABLET_SIZE = 157840048128 / 720 = 219222289 (which equals 2.04GB)   the end result was 2.04GB, does that mean each tablet has 2.04GB? ...
