When using fate ids in persisted data, its a bit safer to call the canonical() method vs toString() because its more well defined what the intention is.

Could use the following String method then, can leave the rest of the code as is (like check for 2 and assume the field[1] is the entire fate id even if it has ":")
var fields = opid.split(":",2);| public TabletOperationType getType() { | ||
| var fields = canonical().split(":"); | ||
| Preconditions.checkState(fields.length == 2); | ||
| Preconditions.checkState(fields.length == 4); |

Could also use split(":",2) in this method.
