/* This module is used to test the propagation (replication + AOF) of
|
||
|
|
* commands, via the RedisModule_Replicate() interface, in asynchronous
|
||
|
|
* contexts, such as callbacks not implementing commands, and thread safe
|
||
|
|
* contexts.
|
||
|
|
*
|
||
|
|
* We create a timer callback and a threads using a thread safe context.
|
||
|
|
* Using both we try to propagate counters increments, and later we check
|
||
|
|
* if the replica contains the changes as expected.
