            ServiceStack.Redis WaitBeforeForcingMasterFailover
            Asked 2021-Apr-30 at 09:01


            I'm trying to understand the motivation behind existence of WaitBeforeForcingMasterFailover property (and the code associated with it) inside of ServiceStack.Redis.RedisSentinel.

            If I interpreted the code right - the meaning behind this property seems to cover cases like:

            1. We have a connection to a healthy sentinel that tells us that a master is at host X
            2. When we try to establish a connection to the master at host X - we fail due to some reason.

            So the logic will be - if we continuously fail to create a connection to X for WaitBeforeForcingMasterFailover period - initiate a force failover.

            The failover does not need to reach a quorum and can elect a new master just with 1 sentinel available.

            SENTINEL FAILOVER Force a failover as if the master was not reachable, and without asking for agreement to other Sentinels (however a new version of the configuration will be published so that the other Sentinels will update their configurations).


            The way it seems to me - this feature can be beneficial in some cases and troublesome in other cases.

            For example in case of a network partition if a client is left connected to a minority of sentinels (they can't reach a quorum) and these sentinels point to a master that is no longer reachable - this force failover option will trigger a failover within reachable partition, thus potentially creating a split brain situation.

            Coming from Java background I also haven't seen such features available in popular redis clients such as Jedis and Lettuce.

            This got me wondering on the following questions:

            1. Are there strong reasons for this feature to be enabled by default? (I understand that you can effectively disable it if you want to by setting a huge value in it). Do they really worth the risk of interfering with natural sentinels workflow and potentially introducing problems like the one I've mentioned before?

            2. Will the library work fine with this option disabled? Are there are cases that I might have missed and turning this feature off will lead to problems even with some happy paths (no network partition, just regular failovers because of a deployment or a sudden node failure)?



            Answered 2021-Apr-30 at 04:41

            It's a fallback that if RedisSentinel is unable to establish a connection to a master client within 60s (default) it will instruct the connected sentinel to force a failover.

            You can increase the wait time when configuring RedisSentinel:



            ServiceStack.Redis relationship between RedisSentinelWorker and RedisPubSubServer
            Asked 2021-Apr-20 at 16:31


            I'm curious what is the relationship between RedisSentinelWorker and RedisPubSubServer.

            From what I've observed the library holds at most 1 active sentinel connection even if there are more sentinel hosts available. That sentinel connection is wrapped in RedisSentinelWorker, which wraps RedisPubSubServer under the hood.

            What bothers me is that RedisSentinelWorker and RedisPubSubServer might actually represent connections to two different sentinels.

            Here is why this is happening:



            Answered 2021-Apr-20 at 16:31

            RedisPubSubServer provides a managed Pub/Sub Server for processing Redis Pub/Sub messages.

            RedisSentinelWorker uses RedisPubSubServer to listen for sentinel messages, it was looking at connecting to any of the available active Sentinel Hosts for Sentinel message events but I can see how it would be more intuitive to only look at the sentinel host the worker is currently configured with so I've changed the behavior in this commit which will be available in the next v5.11 release.



            ServiceStack.Redis authentication Redis Sentinel + Redis
            Asked 2021-Apr-20 at 15:12

            The problem:

            It is not obvious how to correctly authenticate with:

            • sentinels
            • redis instances themselves

            when using the ServiceStack.Redis solution.

            According to the docs a proper way to provide a password for redis/sentinel is to set it via URLs in the following manner:



            Answered 2021-Apr-20 at 15:12

            You can use a RedisSentinel HostFilter to customize the connection string for the individual hosts the sentinel connects to, e.g:



            ServiceStack.Redis RedisTypedClient TTL
            Asked 2021-Mar-03 at 18:11

            I'm using ServiceStack.Redis v5.10.4 and trying to set the TTL using the following code:

            Note: mClientsManager = IRedisClientsManager ttl = TimeSpan?

            I've just fixed this typed API in this commit. This change is available from the latest v5.10.5 that's now available on MyGet.

            Alternatively you can explicitly change the TTL for a key using this async API:



            Connecting to TSL Redis Cloud using ServiceStack.Redis
            Asked 2021-Jan-15 at 13:45

            I'm attempting to use ServiceStack.Redis to connect to a cloud based Redis instance using SSL Certificates. The ServiceStack documentation provides information on how to connect to an Azure based Redis using SSL, but has no information or examples on how to connect to a non Azure Redis instance.

            I've got a pem, crt, and key file but nothing I do with them seems to actually pass them across to the service. I've set ssl=true&sslprotocols=tls12 in the connectionstring which seems like the first step, but beyond that I'm not sure what I should be doing to correctly pass across the certificate for verification

            EDIT: Current Code



            Answered 2021-Jan-15 at 01:20

            ServiceStack.Redis uses .NET's SslStream to establish its SSL connection where you can configure its RemoteCertificateValidationCallback to validate whether to accept the specified certificate for authentication:

            Could not load file or assembly System.Runtime.CompilerServices.Unsafe
            Asked 2020-Dec-04 at 01:36

            I created a Visual Studio (Community 2019) project with C# using ServiceStack.Redis. Since it is C#, I use Windows 10 (there is a Redis version for Windows but it is really old and as I know, it is unofficial so I am afraid that might be the problem). Here is an excerpt from my code:



            Answered 2020-Jul-07 at 06:58

            I assume that your are using .NET Framework. This error is known for ServiceStack.Redis and is tracked on GitHub. It occurs because you use libraries that depend on different versions of System.Runtime.CompilerServices.Unsafe. These transitive dependencies need to be resolved and consolidated to end up with one assembly in your output folder. You will end up with the latest of these versions. Consequently, if one of the libraries depends on a specific version that is older, it will not be found.

            The bug that causes this issue is fixed in System.Runtime.CompilerServices.Unsafe 4.6.0. Use binding redirects, to load the specific version of the assembly that you need. Insert this snippet into all of your app.config files.



            How to represent this structure in Redis
            Asked 2020-Jul-16 at 10:50

            Let's say I'm building a cards game (I'm using an analogy as I can't disclose the original project details). Consider the following structure:



            Answered 2020-Jul-16 at 10:50

            Create a redis set for each card dealer.
            For example,

            "dealer_1_set" : ["91,"A1"]

            "dealer_2_set" : ["A2,"A3"]

            "dealer_3_set" : ["B9,"B10","36"]

            For each card rejected by John, maintainn a redis set for him.

            "cards_rejected_by_john_set" : ["91","A3","36"]

            Now to calculate the available cards from dealer 1 and dealer 2 for John

            use redis command

            SINTER dealer_1_set dealer_2_set ... (add more dealer sets if you want)

            You get new set, say temp_set ["91","A1","A2,"A3"]

            Then use redis command

            SDIFF temp_set cards_rejected_by_john_set

            Then you get ["A1", "A2"] , which is the result.

            The above operations should be pretty fast. But to make the above actions atomic, you'll need to write a Lua script.



            ServiceStack.Redis: PooledRedisClientManager and RedisManagerPool waits for prev req to finish
            Asked 2020-May-30 at 23:50

            I am testing out the Redis "full duplex" communication as shown here, and reading the docs, I thought that the PooledRedisClientManager as well as RedisManagerPool have a pool of clients, and thus being able to process several MQ messages in parallel.

            However, in the test project, found here on Github, it seems to me that this is not the case, or I am missing something. The solution consists of:

            • EventPublisher: .NET Core WinForms application for publishing Hello DTOs to the MQ
            • EventConsumer: .NET Core WinFOrms application that has Service impl for handling Hello DTOs

            I added a Thread.Sleep inside the HelloService Any(Hello req) and when I from the EventPublisher send several Hello DTOs quickly, I was expecting them to be handled concurrently in the EventConsumer, as I thought the pool of clients would be used. This, however, doesn't seem to be the case.

            The HelloResponses are handled one after the other, on the same thread it seems. Please take a look at this short video:


            Here, I fire off three Hello DTOs to the MQ in quick succession, and in the Output window in VS, you can see that the three DTOs are handled one after each other.

            I did not find a setting in PooledRedisClientManager nor RedisManagerPool where I could specify the pool size.



            Answered 2020-May-03 at 23:33

            I thought that the PooledRedisClientManager as well as RedisManagerPool have a pool of clients

            This statement is true.

            and thus being able to process several MQ messages in parallel.

            This is an invalid conclusion that's meaningless without context. The Pooled Redis Client Managers do not do any execution themselves, i.e. they only manage a pool of redis clients meaning when a client is retrieved from the pool:
