StackExchange.Redis | General purpose redis client | Command Line Interface library

Is it possible to run lua script on particular server endpoint using StackExchange.Redis server.Execute ( ExecuteAsync) call?

currently using following code:

I'm testing a simple project deployment, but after deploying it, the project has this error.I'm testing a simple project deployment, but I'm getting errors like the following in StackExchange.Redis when running.

I'm trying to create a powershell script to clear a redis cache, it's in Azure but I don't think that's relevant. I've seen 2 examples which I'm trying to copy where people have loaded StackExchange.Redis.dll into their script: https://www.powershellgallery.com/packages/Saritasa.Redis/1.2.0/Content/Saritasa.Redis.psm1 and Clearing Azure Redis Cache using PowerShell during deployment.

I've downloaded the current StackExchange.Redis.dll from nuget.org. I've tried to load it on 2 servers, one with .Net 4.61 installed, the other with .Net 4.8. I get the same problem on both.

If I try to use [System.Reflection.Assembly]::LoadFrom I get as below:

I encountered some strange behavior while mapping StreamEntry from StackExchange.Redis library to a C# record. While I found the way to write the mapping to make it work, I still do not understand, why does it work only this way (probably due to limited knowledge of AutoMapper internals). Also, I think this could be an example to anyone who hits this problem itself.

Short introduction: I was migrating .Net 5 project using StackExchange.Redis & AutoMapper to .Net 6, same time updating all the packages used. Automapper became version 11 and StackExchange.Redis version 2.2.88. When I ran our unit tests, mapping validation suddenly failed. I didn't change a lot in mappings, replaced only ForAllOtherMembers with ForAllMembers and it was quite strange for me.

The problem itself: .ForMember(dest => dest.Id, opt => opt.MapFrom(src => src.Id)) directive is invalid if src object is StreamEntry. It just throws error "Error mapping types." on validation like if there was no mapping!

Solution: After some trying around, I've managed to find out that you should use not MapFrom(Expression> mapExpression), but MapFrom(Func mappingFunction) and everything works. So just changing code line above to .ForMember(dest => dest.Id, opt => opt.MapFrom((src, _) => src.Id)) magically fixed everything.

Questions:

1. Why? I think this is related to how RedisValue is implemented, but I really don't understand why it stopped working in .Net 6 with AutoMapper 11.
2. To map all members that have string type we use .ForAllMembers(opt => opt.MapFrom(src => src[opt.DestinationMember.Name])) and it still work as it was, however if you try to replace it with .ForAllMembers(opt => opt.MapFrom((src, _) => src[opt.DestinationMember.Name])), it will break.

.Net 6 console example that shows both of issues and correct way to map could be found here. TLDR: Configurations A & C are invalid and B is how it should be done.

I am having some different scenario. I have redis hash for my project. The structure is as follow:

Earlier I have hosted a dotnet core web application in IIS, the app interacts with Redis using StackExchange.Redis (2.0.601) client For every request, it will make a Redis get & set when throughput is more than 1k calls per minute to Redis on an average it took 1-3ms for each interaction

Now we have hosted the same app in docker Linux container and started facing latency in Redis when throughput is more than 1k calls per minute its taking 40-70ms for each Redis interaction

I tried the following things but the issue was not resolved Upgraded the StackExchange.Redis client to the latest stable version Verified if multiple connections to Redis are made (Using only one connection for all Redis interactions)

I am trying to delete a Redis Key. I am using the StackExchange.Redis library and have tried searching on StackOverflow for a way to delete a key. I found this link: StackExchange Redis delete all keys that start with

But my library does not have a method called Database.KeyDelete. How do I get that method?

I am using StackExchange.Redis with NRediSearch in .Net core application.

I have a .Net DataTable and have created hash keys from the data within this DataTable using using IDatabase.HashSetAsync method and they look like below -

Does implementing a ConnectionMultiplexer pool make sense if we use it for synchronous methods?

So by pool I mean creating multiple instances of StackExchange.Redis ConnectionMultiplexer, storing those objects and when I want to communicate with Redis server I take the least used one from the pool. This is to prevent timeouts due to large queue size as per No. 10 suggestion in this article: https://azure.microsoft.com/en-us/blog/investigating-timeout-exceptions-in-stackexchange-redis-for-azure-redis-cache/

I'm having doubts because I'm not sure how can a queue even happen if connectionMultiplexer blocks a thread until a call returns.

It seems to me that having a pool is pointless with sync method calls, but Redis best practice articles suggest creating this kind of pool regardless of method type (sync/async)
