| KahaDB : An Embedded Lightweight Non-Relational Database |
| ======================================================================= |
| |
| Goals: |
| * Provide a simple collections based interface for storing persistent |
| data. |
| * Provide a lower level key value interface for storing data. Secondary |
| keys should be supported. |
| * Fast recovery |
| |
| Status: |
| * Moved the org.apache.activemq.kaha package into this module |
| and renamed it as org.apache.kahadb |
| * Moved a refactored version of the low level indexing logic |
| used by Apache xindice to the org.apache.kahadb.xindice page. |
| |
| TODO: |
| * None of our current index support fast recovery. They suffer |
| from partial page write failures so on a crash, they have |
| to be fully rebuilt from the data logs. |
| * Indexes should know what the last transaction id that updated |
| it, so that missing operations can be replayed. |
| * Investigate implementing data log replication for HA. |
