Hi, yonghu
I am not sure the following timestamp info. whether valuable for you, post
it anyway.
So, I wonder
1. If there are any predefined semantics of TS in HBase or the semantics of
TS is application-specific?
As I know, the timestamp is mainly used for
1. fetch order: from newest to
Can you make NetworkSpeed as column family ?
This way you can treat individual suppliers as columns within the column
family.
So for user Tom has a new supplier d instead of supplier c and its speed
is 15K:
rk NetworkSpeed
cd
Tom {10K:1}
Tom {15K:2}
Hi, Ted
Thanks for your response. This is also the way I use to avoid the problem.

In {10K:1, 20K:3, 15K:5}, what does the value (1, 3, 5) represent ?

Hello,
In my understanding, the timestamp of each data version is generated by Put
command. The value of TS is either indicated by user or

Can you tell me why readings corresponding to different timestamps would
appear in the same row ?

Not sure I follow.
You have a single row with two columns?
In your scenario you'd see that supplier c has 15k iff you query the latest
data, which seems to be what you want.
Note that you could also query as of TS 4 (c:20k), TS3 (d:20k), TS2 (d:10k)

To Ted,

Is that mean the data versions which belong to the same row should at least
have the same timestamps?
For adding a row into HBase, I can use single Put instance, for example,
Put put =
