us, and *how* exactly this can be implemented to have good changes
of a merge. Otherwise it is probably wasted work! Thank you
-DISKSTORE TODO
-==============
-* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
-* Implement sync flush option, where data is written synchronously on disk when a command is executed.
-* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
-* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
-* Fix RANDOMKEY to really do something interesting
-* Fix DBSIZE to really do something interesting
-* Add a DEBUG command to check if an entry is or not in memory currently
+API CHANGES
+===========
+
+* Turn commands into variadic versions when it makes sense, that is, when
+ the variable number of arguments represent values, and there is no conflict
+ with the return value of the command.
+
+CLUSTER
+=======
+
+* Implement rehashing and cluster check in redis-trib.
+* Reimplement MIGRATE / RESTORE to use just in memory buffers (no disk at
+ all). This will require touching a lot of the RDB stuff around, but we may
+ hand with faster persistence for RDB.
+* Implement the slave nodes semantics and election.
+* Allow redis-trib to create a cluster-wide snapshot (using SYNC).
+* Allow redis-trib to restore a cluster-wide snapshot (implement UPLOAD?).
+
+SCRIPTING
+=========
+
+* MULTI/EXEC/...: should we do more than simply ignoring it?
+* Prevent Lua from calling itself with redis("eval",...)
+* SCRIPT FLUSH or alike to start a fresh interpreter?
+* http://redis.io/topics/sponsors
APPEND ONLY FILE
================
OPTIMIZATIONS
=============
+* Avoid COW due to incrementing the dict iterators counter.
* SORT: Don't copy the list into a vector when BY argument is constant.
* Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
* Read-only mode for slaves.
-
-REPORTING
-=========
-
-* Better INFO output with sections.
+* Redis big lists as linked lists of small ziplists?
+ Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.
RANDOM
======
+* Server should abort when getcwd() fails if there is some kind of persistence configured. Check this in the cron loop.
* Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
* Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
KNOWN BUGS
==========
-* What happens in the following scenario:
- 1) We are reading an AOF file.
- 2) SETEX FOO 5 BAR
- 3) APPEND FOO ZAP
- What happens if between 1 and 2 for some reason (system under huge load
- or alike) too many time passes? We should prevent expires while the
- AOF is loading.
-
+* #519: Slave may have expired keys that were never read in the master (so a DEL
+ is not sent in the replication channel) but are already expired since
+ a lot of time. Maybe after a given delay that is undoubltly greater than
+ the replication link latency we should expire this key on the slave on
+ access?
