Study the OpenTSDB at StumbleUpon described by Benoit "tsuna" Sigoure
(ts...@stumbleupon.com) in the
HBaseCon talk called "Lessons Learned from OpenTSDB".
His team have done a great job working with Time-series data, and he
gave a lot of great advices to work with this kind of data with HBase:
How does it deal with multiple writes in the same milliseconds for the same
rowkey/column? I can't see that info.

Can you give an example of what you are trying to do and how you would
use both the writes coming in at the same instant for the same cell
and why do you say that the nanosecond approach is tricky?

Hi All,
I have a secondary index(inverted index) table with a rowkey on the basis
of Timestamp of an event. Assume the rowkey as .
I also store some extra(apart from main_table rowkey) columns in that table
for doing filtering.
The requirement is to do range-based scan on the basis of time of

Here you can find the discussion, trade-offs and working code/API (even for
M/R) about this and the approach you are trying out.

If you read my solution carefully. I am already doing that.
Thanks,

Hey Anil,
The solution you've described is the best we've found for Phoenix (inspired
by the work of Alex at Sematext).
You can do all of this in a few lines of SQL:
CREATE TABLE event_data(
who VARCHAR, type SMALLINT, id BIGINT, when DATE, payload VARBINARY
CONSTRAINT pk PRIMARY KEY (who,
Hi James,
Great to hear that Phoenix supports this kind of table schema. Seems like
i'll go ahead with Bucketing for timeseries data.
Thanks,
Anil
