+===== RBD workloads =====
+  The general recommendation is to have block.db size in between 1% to 4% of block size. For RGW workloads, it is
+  recommended that the block.db size isn’t smaller than 4% of block, because RGW heavily uses it to store its
+  metadata.
+  For example, if the block size is 1TB, then block.db shouldn’t be less than 40GB.
+  For RBD workloads, 1% to 2% of block size is usually enough.
+rocksdb = 2%
