http://inaka.net/edis/Edis_Implementing_Redis_In_Erlang.pdf

current branch crashes with no errmsg unless .hosts.erlang file is found

creating .hosts.erlang file in home dir solves the issues

Somehow [xx]STORE is extra faster than [xx] when compared to redis (check it on the edis benchmarks) for all such set commands. We need to fix that.

Erldocs changed its command-line syntax, we should cope with it.
To reproduce the error, try make doc without a doc folder

fix it!

I have a problem with make run

What should I do?

We need to add tests for Pub/Sub commands.
We will need to improve pubsub support in erldis, too.

I am using redis-py client. It expects an int answer from SADD command, but

  File "worker.py", line 305, in update_list
    rserver.sadd(key, *members)
  File "/usr/local/lib/python2.7/dist-packages/redis/client.py", line 1477, in sadd
    return self.execute_command('SADD', name, *values)
  File "/usr/local/lib/python2.7/dist-packages/redis/client.py", line 565, in execute_command
    return self.parse_response(connection, command_name, **options)
  File "/usr/local/lib/python2.7/dist-packages/redis/client.py", line 579, in parse_response
    return self.response_callbacks[command_name](response, **options)
Thread-2    <type 'exceptions.TypeError'>: int() argument must be a string or a number, not 'NoneType'

Same thing happens with LLEN. What does it mean? According to Redis protocol, this shouldn't happen.

Also, I get sometimes records like this in logs:

00:52:49.556 [info] Unexpected info: {#Ref<0.0.0.38537>,{ok,<<MY_DATA_HERE>>}}

It has nothing to do with None answer, happens rarely, but can be related somehow.
I had same issues with building as in #44, maybe this is also can be related.

@zohaibhassan recommends trying Tokyo Cabinet as a backend, since it's pretty fast and mature.

HMSET performance is awful. That's because we're simply looping through the values and executing a HSET for each one. We should find a way to set all values in a single pass.

Edis should not let clients to try to use AUTH when there is no password set.

Make the system auto-multi-node aware, most likely using:

• net_adm:world()
• .hosts.erlang
• erlang:monitor_nodes()

You can check how that's done on conflux but bear in mind that that application uses a database to keep the node names and we can't.

I hacked in an architecture for user-defined hooks as part of my EF 2012 talk. I wanted to discuss them here so we can figure out if this is the official way we want to do it or we want to tweak it a bit. Code is in my branch as it's not ready for a pull request yet.

The idea is that the administrator adds a edis config item for hooks on a per-datatype basis. The hooks are regular expressions like this:

[{edis, [{list_hooks,[{"foo*",{edis,test_hook}}]}]]

this means for all list operations, any key that starts with foo will trigger the M/F/A

edis:test_hook(Command, Result) 

to run.

Now, the result this function returns is the NEW result for the operation. Important notes:

• the function currently can't change the return type
• the function can throw an error but it doesn't roll back whatever the command did
• the function can't yet easily modify what the command did because it doesn't have the handle to the db

I'm thinking of some interface changes that could expose the internal state of command_runner that would make at least the last item go away, but I need to think through the use cases a bit more.

My main use cases are:

• A "Resque" like queuing system that allows workers to pull off items but auto-restarts after a timeout.
• A similar system where the workers are triggered actively upon pushing an item into the list.
• Auto push items to a downstream system like Rabbit.
• Refresh secondary indexes or keys (facebook friends) when items change.

We need to add tests for Keys commands

Related to Issue #2, MSET and MSETNX performances are awful, too.

It's not currently used and it's not multi-node-safe

First attempt at multi-nod'ing properly…
Connect edis_db processes on different nodes (most likely using pg2) so that, when a put, write, delete or destroy operation is done in the backend of one of them, it's automatically propagated to the rest. get and is_empty should still be executed as they're now.

On http://inaka.github.io/edis/ there's a typo:

"Edis is a protocol-compatable Server replacement for Redis,"

Should be compatible?

We need to add tests for Keys commands

We need a backend that combines the virtues of edis_pb_backend and edis_leveldb_backend. It should keep things in memory but periodically send them to disk using levelDB

We need to rewrite our zset module to improve its performance and readability.

ERROR: compile failed while processing /edis/deps/erldocs: rebar_abort
make: *** [erl] Error 1

I have the R15B03 version of erlang and latest rebar installed. I think it more of an issue with erldocs than edis, but I am not very sure.

Regards
Rajesh

How to reproduce:

$ git clone git://github.com/inaka/edis
$ cd edis/
edis$ make
rebar get-deps compile
==> edis (get-deps)
Pulling lager from {git,"git://github.com/basho/lager.git","master"}
Cloning into 'lager'...
Pulling eper from {git,"git://github.com/mhald/eper.git","HEAD"}

How to fix: change version at edis/deps/eper/src/eper.app.src to 0.60
