NEWS

-Release 1.2 2011-05-16
-----------------------
-
-Fixes for larger databases (tested up to one billion 100-byte entries,
-i.e., ~100GB).
-
-(1) Place hard limit on number of level-0 files.  This fixes errors
-of the form "too many open files".
-
-(2) Fixed memtable management.  Before the fix, a heavy write burst
-could cause unbounded memory usage.
-
-A fix for a logging bug where the reader would incorrectly complain
-about corruption.
-
-Allow public access to WriteBatch contents so that users can easily
-wrap a DB.

TODO

-ss
-- Stats
-
-db
-- Maybe implement DB::BulkDeleteForRange(start_key, end_key)
-  that would blow away files whose ranges are entirely contained
-  within [start_key..end_key]?  For Chrome, deletion of obsolete
-  object stores, etc. can be done in the background anyway, so
-  probably not that important.
-
-After a range is completely deleted, what gets rid of the
-corresponding files if we do no future changes to that range.  Make
-the conditions for triggering compactions fire in more situations?
