Hi all,
I know that the value in hbase is just a byte array. So before I put any
type of data, I should convert it to bytes.
But I found that if I convert String to bytes, I can see the real value in
hbase shell, while If I convert long to bytes, I will see byte array in
hbase shell which is not
Hi Jeff,
Do what is best for the most common use you anticipate will happen on query or
scan. Are you going to be most often displaying the value as a string? If so,
store as string via Bytes.toBytes(String). Or are you most often going to
perform some integer arithmetic or some other operation
Another thing to remember, that if you are using the ASCII expansion
of a integer as a key, it is sorted in _lexographic_ order which is
not numerical order. For example you'll get this ordering in ASCII:
1
12
2
...
You either have to pad with leading 0s, or use big-endian byte
"conversion". Eg:
