Can anyone please tell me how can I perform a transaction in redis while watching the the hash key foo and set a value with key test and value fooTest. The multi is executing with ok but the value is not set in redis.
redisClient.watch("foo", function (err) {
if (err) {
console.log('There was an error while watching the key foo.');
}
// Is this the correct usage of multi with hset i could not find it anywhere in documentation?
// The documentation just says that it will watch the whole hash and trigger if any value of the hash is modified.
redisClient.multi().hset(data.conversationID, helper.lastActivity, data.sentTimeStamp).exec(function (err, result) {
if (err) {
console.log('There was an error while executing the multi query');
}
if (result === null) {
console.log('The transaction was not performed since the data was accessed by someone else during the transaction and changed.');
}
});
});This gives a result [OK] when logged but the value is updated.
is this right https://www.npmjs.com/package/redis-streams or am i off into the blue?
I wanted to understand about redis pub/sub. Say if I have a producer which publish messages on multiple channels.
Now, should I create single subscriber and listen to all channel.
or should I create individual subscriber for every channel?
I want to understands what are the best practices..!

I want to increment a key every n seconds in redis using nodejs.
I thought of implementing it like below :
function func(id1, max){
for(i=0; i < max; i++){
client.incr(id1, (error, value) => {
if(error){
console.log("redis incr failed : " + error);
return error;
}
console.log("updated value : " + value);
});
sleep.sleep(1);
}
client.quit();
return("incr value ended for : " + id);
}
func(id1, max);But then in this case the complete redis incr happens in a stretch and the callback (console.log("updated value : " + value")) happens with delay (sleep 1).
Afaik, it is caused due to the nodejs being synchronous and (I think) the node_redis client being async.
Could anyone here please help me with this ? Thank you in advance!
null or undefined?
I have a set called "allguilds." I am using this to check if an ID is in there and if so apply a different element. But when I load the page It does probably half or so correct then mixes the set and guild ID.
Not working: 0 for guild undefined, set 373596097869905921.
Working: 1 for guild 539185945442910218, set allguilds.
I use this redis.check('allguilds', guild.id).then(function(res). That is
check: (set, guild) => client.sismemberAsync(set, guild).then(function(res) {
console.log(`${res} for guild ${guild}, set ${set}.`)in the Redis file. I check if res === 1 and if so apply the different element Sorry for the edits forgot the markdown
