Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The following page has been changed by stack: http://wiki.apache.org/hadoop/Hbase/HbaseFeatureRequests The comment on the change is: Feature Requests have been implemented or added to JIRA ------------------------------------------------------------------------------ - = Feature Requests = + deleted - Feel free to add feature or enhancement requests below. Note that only in rare occasions will a request be considered for the initial release to keep the effort focused. - - ---- - * Add ability for the user to specify the timestamp of a row, much like in bigtable. (our dataset is already mapped to a specific timestamp). Added ''2007-05-29 16:21:06 by johanoskarsson'' - * '''Implemented'''. See org.apache.hadoop.hbase.!TestTimestamp unit test. - - * Add to HClient something like `HClient#getNearest(Text row, Text [] column, long timestamp)` to return the results that fall closest to provided timestamp (Use case: wayback machine type applications). Also `HClient#getNearest(Text row, Text [] column, long timestamp, long delta)` where `delta` is a maximum for how far to go into the future -- or past -- beyond the supplied timestamp. Added ''2007-05-29 by stack'' - - * Clients should be able to open an !OutputStream for putting a value into a table. Right now the only interface for insertion is via a byte[], which severely limits the flexibility of the system. Added ''2007-10-08 by stuhood'' - * Tell us more Stu why you need this feature? (Because you want to write BLOBs of multiple Gigabytes into an hbase cell?) - - * Add ability to read a cell's timestamp. This can be used for sorting columns or removing old columns. - - This is possible with scanners as next() returns the row key and the time stamp in the H!StoreKey. Are you asking for a similar mechanism for get? -
