If this is actually a bug and not an error on my end, I can create a JIRA

We have done almost no tuning for HBase, but I'd be willing to bet
that it would handily beat MySql in a drag race.

Stonebraker has a new column oriented store called H-Store. It is also talked
about in the paper.
And now I'll shut up. I didn't intend to create such a firestorm.

Yes, see hbase.HColumnDescriptor.java compression is controlled on a per column
family basis.

won't), and both the update and the next scanner.next should both fail.
Hope that helps.

be more inclined to merge the scripts since they would have more in common.
For now, I think keeping them separate is probably the right thing to do.

Subject: HBase question on HRegions server
Hi,
I am confused with some thing in HBase.
1. All data is stored in HDFS. Data is served to clients
in the META
directly or ask the Master to write a new tablet row in the META?
It depends on the circumstances. Sometimes the region server does,
sometimes the master does.
thanks.

Currently, HBase supports specifying a maximum number of versions to
keep. Older versions are removed during compaction.
However, we do not currently support a TTL for columns. Please enter
a Jira using the component contrib/hbase and request a feature improvement.
Thanks.

Well, it depends on how the Text object is initialized. If it is initialized
with a String, it sets its internal length to the length of the string.

Hi
The only examples we have at this point are the unit tests. They
are rather contrived but it's what we have. You can find them in
the source tree under

Are you referring to snapshots of the entire DFS or of HBase?

You're probably right - column names are not base64 encoded.
Isn't the contract of
a fault tolerant
upgrade utility, should HBase's file structure change again.
Additionally, we will be able to provide the equivalent of
fsck for HBase after HADOOP-2478.
