+ | ===== 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% | ||
+ | waldb = 0.02% | ||
