Kubernetes: When using `Deployment` resources, be aware that their default strategy is "Recreate" which can lead to downtime during updates. Consider setting `strategy: RollingUpdate` to minimize service disruption. #k8s #cloudnative

Kubernetes: Use `DeploymentConfig` instead of `ReplicationController` for stateless applications, as it provides more features like rolling updates, self-healing, and rollbacks. #k8s #devops

When using Docker Compose, make sure to set `docker-compose.yml` file's `build` directive to `.` when building an image from your project directory to avoid copying unnecessary files and speed up the build process. #Docker #DevOps

In C++, when using `std::map` with custom key types, ensure your key type implements `<operator<` correctly to avoid unexpected behavior. This ensures correct sorting and iteration.

Redis's `SET` command has an optional `NX` (non-exist) flag that allows atomic set operations only if the key doesn't exist. This prevents race conditions and ensures consistent data integrity. #redis #distributedsystems

When working with Kafka, remember that partitioning key should be designed to ensure even data distribution across partitions, as uneven distribution can lead to performance issues. Use a combination of timestamp and user_id as the partitioning key to achieve this. #KafkaTips ...

In C++, when using `const` with a non-static member function, it only prevents the object's state from being modified, not the object itself. This means the object can still be copied or moved. #cpp #programming

When designing distributed systems, consider using an eventual consistency model with strong consistency guarantees for write-heavy services, while using weak consistency models for read-mostly services to optimize performance and availability. #SystemDesign #DistributedSystems

Redis's built-in `WATCH` command allows you to detect concurrent modifications of a key while executing a transaction, preventing lost updates & ensuring atomicity. Use it to avoid conflicts in distributed systems! #Redis #Concurrency

In Go, when using channels as a queue, remember that `range` on a channel returns the sent value and a boolean indicating whether the loop should continue. This allows for efficient handling of closed channels without needing explicit checks.

When designing systems with multiple microservices, consider using a centralized logging service like ELK (Elasticsearch, Logstash, Kibana) to collect and analyze logs from each service, allowing for easier debugging, monitoring, and incident response.

When using JavaScript's `JSON.stringify()`, be aware that it will recursively serialize all enumerable properties, including those inherited from prototype chains. Use `JSON.stringify(obj, replacer, space)` with a custom `replacer` function to filter out unwanted properties.

In Kubernetes, when using persistent volumes (PVs) with StatefulSets, ensure that PV's reclaim policy is set to "Retain" to prevent data loss during pod recreation or node updates. #k8s #persistence
