Redis TODO and Roadmap
-VERSION 1.2 TODO (Zsets, Integer encoding, Append only journal)
-===============================================================
-
-Most of the features already implemented for this release. The following is a list of the missing things in order to release the first beta tar.gz:
-
-* Continue adding tests accordingly to gcov output.
-
VERSION 1.4 TODO (Hash type)
============================
-* Blocking LPOP (BLPOP).
-* Hashes (HSET, HGET, HEXISTS, HLEN, ...).
+* BRPOPLPUSH
+* RPOPLPUSH should notify blocking POP operations
* List ops like L/RPUSH L/RPOP should return the new list length.
+* Save dataset / fsync() on SIGTERM
+* MULTI/EXEC should support the "EXEC FSYNC" form
+* Synchronous Virtual Memory
+* BLPOP & C. tests (write a non blocking Tcl client as first step)
+
+Virtual Memory sub-TODO:
+* Check if the page selection algorithm is working well.
+* Fix support for large files
+* Divide swappability of objects by refcount
+* While loading DB from snapshot or AOF, swap objects as needed if maxmemory
+ is reached, calling swapOneObject().
+* vm-swap-file <filename>. The swap file should go where the user wants, and if it's already there and of the right size we can avoid to create it again.
VERSION 1.6 TODO (Virtual memory)
=================================
-* Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd)
+* Asynchronous Virtual Memory
+* Hashes (HSET, HGET, HEXISTS, HLEN, ...).
VERSION 1.8 TODO (Fault tollerant sharding)
===========================================
* Specially encoded memory-saving integer sets.
* A command to export a JSON dump (there should be mostly working patch needing major reworking).
+* Specially encoded sets of integers (this includes a big refactoring providing an higher level layer for Sets manipulation)
+* ZRANK: http://docs.google.com/viewer?a=v&q=cache:tCQaP3ZeN4YJ:courses.csail.mit.edu/6.046/spring04/handouts/ps5-sol.pdf+skip+list+rank+operation+augmented&hl=en&pid=bl&srcid=ADGEEShXuNjTcZyXw_1cq9OaWpSXy3PprjXqVzmM-LE0ETFznLyrDXJKQ_mBPNT10R8ErkoiXD9JbMw_FaoHmOA4yoGVrA7tZWiy393JwfCwuewuP93sjbkzZ_gnEp83jYhPYjThaIzw&sig=AHIEtbRF0GkYCdYRFtTJBE69senXZwFY0w
SMALL ONES:
* Give errors when incrementing a key that does not look like an integer, when providing as a sorted set score something can't be parsed as a double, and so forth.
* MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41
+* Don't save empty lists / sets / zsets on disk with snapshotting.
+* Remove keys when a list / set / zset reaches length of 0.
-SHORT/LONG TERM RANDOM TODO ITEMS
-=================================
+THE "MAYBE" TODO LIST: things that may or may not get implemented
+=================================================================
Most of this can be seen just as proposals, the fact they are in this list
it's not a guarantee they'll ever get implemented ;)
* zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block. Already done for Mac OS X.
* Read-only mode.
* Pattern-matching replication.
-* Don't save empty lists / sets / zsets on disk with snapshotting.
-* Remove keys when a list / set / zset reaches length of 0.
* Add an option to relax the delete-expiring-keys-on-write semantic *denying* replication and AOF when this is on? Can be handy sometimes, when using Redis for non persistent state, but can create problems. For instance should rename and move also "move" the timeouts? How does this affect other commands?
