RocksDB checkpointing dir per TM

[Taher Koitawala]

Hi All,
          Our current cluster configuration uses one HDD which is mainly
for root and an other NVME disk per node, [1]we want make sure all TMs
write their own RocksDB files to the NVME disk only, how do we do that?

[2] Is it also possible to specify multiple directories per TMs so that we
have an even spread when the RocksDB files are written?

Thanks,
Taher Koitawala
