QUESTION
i'm using predis integrated with laravel, in some case predis got connection timeout, but when i'm trying to connect redis server via cli, i got connected perfectly
can anyone help me how to resolve it ?
...ANSWER
Answered 2022-Apr-09 at 11:30As you can see in the debug data your Host is set to Host. I'm assuming you got redis on a localhost setup, in your .env file set the following variable. Also your password seems off, adjust that also, most local redis installs has a blank password.

I am trying to install league/flysystem-aws-s3-v3 package.. My current laravel version is 5.7.*
When I try to run composer require league/flysystem-aws-s3-v3 "^1.0"
I get lots of issues :(
...ANSWER
Answered 2021-Jul-26 at 07:05Composer is telling you what is wrong. It wants PHP8 and you offer php7.4, so it doesnt install.
From the comments it also says that laravel 9 is in development. As you're stuggling with this, I dont recommend using that version and go one back, using 8.
What I recommend doing (and what I've been doing lately to a much larger website), is first to run composer update. That way, you update all packages in a sem-ver method (so only minor updates). Deploy that to your server.
Than you can use compser outdated to see what you can update. Do composer update package/name -W (with all dependencies), just one at a time. if you run into a problem, just goto the next one, sometimes after you come back you can still do it.
If you go to packagist.org you can serach your package and see what the current versions are. Sometimes you can go up a few mayors, sometimes one, sometimes only minor. It's a bit of a puzzle.

I try to configure two cache pools in my Synfony5 app to use a certain namespace and set a default expiration date for the items. After trying for the umpteenth time the umteenth variation I get the feeling that my configuration is going in circles.
What I understood so far: In the constructor of the RedisAdapter you can set the namespace and the default expiration time In the createConnection method you set the url of your redis server.
However the constructor of the RedisAdapter seems to already need a redis client (= redis connection?) RedisAdapter:

QUESTION
By default, Laravel will use the phpredis extension to communicate with Redis but We can install predis in application. do I need to install predis in project? what is difference between phpredis and predis in laravel?
...ANSWER
Answered 2021-Jun-27 at 07:08phpredis is a binary package and pecl extension for php.which makes it faster than predis.
but you need root permission to install phpredis extension.when you use some webhost that do not support customize environment,make it impossible to run you appllication.
on the other hand.predis use pure php code to communicate with redis server.so there is no local php extension requirements.but it's a little slower.
so you can deploy you application to any webhost that support php.
As I remember.laravel default use predis to make it minial requirements.

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

QUESTION
I recently performed a rather large update to this web app, and for the most part it went off without a hitch... Until the app tries to send an SMS notification from staging/production.
The upgrade from laravel 7.x to 8.x was quite simple and straightforward. At the same time we also installed Laravel Horizon. Everything went according to plan, and all works fine locally.
When we deploy to staging/production however, queued SMS notifications fail with the following exception:
ReflectionException: Class Http\Adapter\Guzzle6\Client does not exist in /home/forge/dev.example.com/releases/20210609194554/vendor/laravel/framework/src/Illuminate/Container/Container.php:836
Looking in the stack trace we can see that Nexmo is the culprit:
#5 /home/forge/dev.example.com/releases/20210609194554/vendor/nexmo/laravel/src/NexmoServiceProvider.php(150): Illuminate\Foundation\Application->make()
However in our composer.json file we are requiring Guzzle 7 with the following:
"guzzlehttp/guzzle": "^7.3",
It is worth mentioning again at this point, I have no issues sending SMS locally, the main difference between local and staging environments is that locally I use Laravel Valet and Staging uses Laravel Envoyer.
What I've tried so far:
- Changing
"guzzlehttp/guzzle": "^7.3"to"guzzlehttp/guzzle": "^6.5|^7.3" - Running
php artisan horizon:purgeandphp artisan horizon:terminateboth manually and in a deployment hook. - Restarting the laravel horizon daemon on forge.
- trying
php artisan queue:restart - running
composer dump-autoloadandcomposer dump-autoload -o - deleting composer.lock and the vendor/ directory from current/ then running
composer install - Restarting PHP, Nginx, and eventually the entire server :(
and more...
Any help is greatly appreciated

Answered 2021-Jun-09 at 23:40I see that the NexmoServiceProvider is trying to use the defined http_client in the config, so can you share what the .env has for NEXMO_HTTP_CLIENT ? I am pretty sure you have something wrong there or even not defined.
And this is what it is defined in the config/nexmo.php related to that config:
QUESTION
I need a method to get all keys by prefix to delete them.
I've read about the KEYS not being suitable for production, so i made a few tests to check performance. Im using predis 1.1.6 (php) and i tested both in my local machine and in a testing AWS environment with elasticache redis. Im doing this on a node with about 300k items.
Im using prefixes: CLIENT/ID_CLIENT/MODULE:HASH which translates in client/9999/products:452a269b82c199ef27f5a299e3b0f98531216ccf
So i need to search and delete all keys from a client and module. Since i use prefixes, i've set the correct prefix and used the predis keys method:
...ANSWER
Answered 2021-Apr-15 at 14:26KEYS in production
First its important to understand why KEYS shouldn't be used in production.
KEYS has a time complexity of O(N), where N is the number of elements of the entire database. NOT how many satisfies the pattern. Since only one command can run at the same time (Redis not being multi-threaded), everything else will have to wait for that KEYS to complete.
see: Why KEYS is advised not to be used in Redis?
According to the docs:
While the time complexity for this operation is O(N), the constant times are fairly low. For example, Redis running on an entry level laptop can scan a 1 million key database in 40 milliseconds.
Warning: consider KEYS as a command that should only be used in production environments with extreme care. It may ruin performance when it is executed against large databases. This command is intended for debugging and special operations, such as changing your keyspace layout. Don't use KEYS in your regular application code. If you're looking for a way to find keys in a subset of your keyspace, consider using SCAN or sets.
This would indicate that if you have less than a million records, using keys should be okay ish. But as your database grows, or you have more concurrent users, issues may arise.
KEYS
SCAN
A common alternative to KEYS is SCAN (which is what you are using). Note that this is still a bad alternative, as its very similar to KEYS, except that the result is returned in chunks, and has O(N), where N is the number of elements of the entire database.
The advantage is that it doesn't block the server, but it has the same time complexity has KEYS. In fact, if all you want to get is the result, and don't care about blocking the database, it can be slower than KEYS as it has to perform multiple queries (as you have seen).
A much better alternative is to use a HSET.
When you want to put elements into a HSET, use:

Install predis
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
