To handle cases of recreation of bucket with the same name, something like
this could be done.
1. Bucket cache should store bucket Object ID along with other required
metadata such as bucket/volume name.
2. When a request is sent to the server say a rename request , on the OM
there needs to be a check b/w bucketObjID in the request and bucketObjID of the
stored BucketInfo object on the DB. If they mismatch, send an error response
asking the client to invalidate its cache.
```java
OmBucketInfo rocksdbBucketInfo =
bucketTable.get(request.getRenameRequest().getBucketName);
if
(request.getRenameRequest().getBucketObjectID!=rocksdbBucketInfo.getBucketObjectID){
// return error response with 'INVALIDATE_BUCKET_CACHE";
}
```
