We konw that murmur3_partitioner_ignore_msb_bits is used to select which bits are used for sharding. Is its value range between 0 and num_token? Its default value is 12. If we deploy a large-scale cluster (180 nodes), should its value be increased?
The range of valid values for this option is [0, 64), i.e. from 0 to the number of bits in the 64 bit token value. This option designates how many bits to ignore from the token’s MSB bits, when calculating the shard that owns this token.
This value is completely orthogonal to the number of nodes in the cluster. No need to change it for large deployments.
