Subject [jira] Commented: (HBASE-725) Maximum ColumnKey Lookup
Date Mon, 07 Jul 2008 16:01:33 GMT

Bryan Duxbury commented on HBASE-725:
-------------------------------------

It doesn't matter if the timestamp part of the qualifier can be anything. Getting the last
by lexical sort should be easy.

> When working with time series data, relative columnKeys 'indexes' are routinely shared
between the columnFamilies of a given row. To acquire the maximum key and increment it for
the next columnKey, you must first get all the keys. A quick lookup of the last columnKey
would benefit as the column size grows over time.
