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. |
