====================
- Added the keep-history option. Set it to false to keep no history.
(Packing is still required for garbage collection and blob deletion.)
- Added the replica-conf and replica-timeout options. Set replica-conf
to a filename containing the location of database replicas. Changes
to the file take effect at transaction boundaries.
- Expanded the option documentation in README.txt.
- Revised the way RelStorage uses memcached. Minimized the number of
trips to both the cache server and the database.
- Added an in-process pickle cache that serves a function similar to the
ZEO cache.
- Added a wrapper module for pylibmc.
- Store operations now use multi-insert and multi-delete SQL
statements to reduce the effect of network latency.
- Renamed relstorage.py to storage.py to overcome import issues.
Also moved the Options class to options.py.
- Updated the patch for ZODB 3.7 and 3.8 to fix an issue with
blobs and subtransactions.
- Divided the implementation of database adapters into many small
objects, making the adapter code more modular. Added interfaces
that describe the duties of each part.
- Oracle: Sped up restore operations by sending short blobs inline.
- Oracle: Use a timeout on commit locks. This requires installation
of a small PL/SQL package that can access DBMS_LOCK. See README.txt.
- Oracle: Used PL/SQL bulk insert operations to improve write
performance.
- PostgreSQL: use the documented ALTER SEQUENCE RESTART WITH
statement instead of ALTER SEQUENCE START WITH.
- Moved MD5 sum computation to the adapters so they can choose not
to use MD5.
- Changed loadSerial to load from the store connection only if the
load connection can not provide the object requested.
- Stopped wrapping database disconnect exceptions. Now the code
catches and handles them directly.
- Use the store connection rather than the load connection for OID
allocation.
- Detect and handle backward time travel, which can happen after
failover to an out-of-date asynchronous slave database. For
simplicity, invalidate the whole ZODB cache when this happens.
- Replaced the speed test script with a separately distributed package,
``zodbshootout``.
- Added the ``zodbpack`` script.
