etcd features and specs

  • Consistency
    etcd uses the Raft consensus algorithm to ensure strong consistency across distributed systems, making it ideal for scenarios where reliable data storage is critical.
  • High Availability
    By distributing data across multiple nodes, etcd ensures high availability and fault tolerance, allowing services to remain operational even if some nodes fail.
  • Simplicity
    etcd offers a simple key-value store interface, making it easy to understand and integrate with other services without requiring complex configurations.
  • Performance
    Optimized for fast reads and writes, etcd can handle large volumes of concurrent requests, making it suitable for high-performance applications.
  • Secure
    etcd provides excellent security features, including SSL/TLS encryption for data in transit and role-based access control to ensure that data access is tightly controlled.

Possible disadvantages of etcd

  • Resource Intensive
    Running etcd, especially in a clustered configuration, can be resource-intensive, requiring significant CPU and memory to ensure optimal performance and reliability.
  • Operational Complexity
    Although etcd itself is simple, managing a distributed etcd cluster can become complex, requiring expertise to configure and maintain properly.
  • Data Volume Limitations
    etcd is not designed as a general-purpose database and has limitations on how much data it can efficiently store, typically up to a few gigabytes per cluster.
  • Write Throughput
    The write throughput of etcd can be a bottleneck under heavy load, as it needs to ensure data consistency across nodes, which can introduce latency.
  • Limited Query Capabilities
    As a key-value store, etcd lacks the advanced querying capabilities of traditional databases, which may limit its use for complex data retrieval operations.

Apache APISIX features and specs

  • High Performance
    Apache APISIX is built on top of Nginx and designed to handle thousands of requests per second. This makes it suitable for high-performance applications and services requiring efficient request processing.
  • Dynamic Configuration
    APISIX allows for dynamic load balancing, routing, and plugin configuration without the need to restart or reload the service, offering robust flexibility and reducing downtime.
  • Extensive Plugin Ecosystem
    APISIX offers a wide range of plugins to extend its functionalities, covering authentication, security, traffic control, and more, allowing for customization and scalability.
  • Open Source and Community-driven
    Being an Apache project, APISIX is open-source and actively maintained by a community of contributors, ensuring continuous improvement and support.
  • Multi-language Support
    APISIX supports multi-language plugins such as Java, Go, and Python, thereby allowing developers to write plugins in the language they are most comfortable with.

Possible disadvantages of Apache APISIX

  • Complexity of Setup
    Setting up Apache APISIX can be complex for new users, requiring familiarity with Nginx and understanding its configuration model, which might involve a steep learning curve.
  • Documentation Gaps
    While the project is actively improved, some users might experience gaps or inconsistencies in the documentation, posing challenges during setup and customization.
  • Limited Enterprise Support
    Compared to some commercial API management solutions, APISIX might lack dedicated enterprise-level support, which could be a concern for organizations requiring rapid troubleshooting and expert assistance.
  • Evolving Features
    As a relatively new project, some features and components may still be evolving, which means users may encounter changes that require adaptation and adjustments over time.

  • Designing a fault-tolerant etcd cluster
    Etcd is an open-source leader-based distributed key-value datastore designed by a vibrant team of engineers at CoreOS in 2013 and donated to Cloud Native Computing Foundation (CNCF) in 2018. Since then, etcd has grown to be adopted as a datastore in major projects like Kubernetes, CoreDNS, OpenStack, and other relevant tools. Etcd is built to be simple, secure, reliable, and fast (benchmarked 10,000 writes/sec),... - Source: dev.to / 6 months ago

  • Fastly and the Linux kernel
    The open source projects Fastly uses and the foundations we partner with are vital to Fastly’s mission and success. Here's an unscientific list of projects and organizations supported by the Linux Foundation that we use and love include: The Linux Kernel, Kubernetes, containerd, eBPF, Falco, OpenAPI Initiative, ESLint, Express, Fastify, Lodash, Mocha, Node.js, Prometheus, Jenkins, OpenTelemetry, Envoy, etcd, Helm,... - Source: dev.to / 11 months ago
  • Is Kubernetes a database? CRDs explained in five minutes
    Each time we create or update a K8s resource, the Kubernetes API stores it in its database — etcd. Etcd is a distributed key-value store used to store all of your resource configurations, such as deployments, services, and so on. A neat feature of etcd is that you can subscribe to changes in some keys in the database, which is used by other Kubernetes mechanisms. - Source: dev.to / 11 months ago

  • Free tier API with Apache APISIX
    Lots of service providers offer a free tier of their service. The idea is to let you kick their service's tires freely. If you need to go above the free tier at any point, you'll likely stay on the service and pay. In this day and age, most services are online and accessible via an API. Today, we will implement a free tier with Apache APISIX. - Source: dev.to / 9 months ago
  • OpenResty on NixOS for an API Gateway
    We have been using Apache APISIX for a while now. It is a high-performance, cloud-native API gateway solution. It also has a nice dashboard for managing APIs. However, I have been looking for a simpler and more portable solution for our use case. In particular, I want to be able manage the API gateway as a NixOS service so that the configuration can be tested and redeployed easily. - Source: dev.to / 9 months ago
  • Advanced URL rewriting with Apache APISIX
    I spoke at Swiss PgDay in Switzerland in late June. The talk was about how to create a no-code API with the famous PostgreSQL database, the related PostgREST, and Apache APISIX, of course. I already wrote about the idea in a previous post. However, I wanted to improve it, if only slightly. - Source: dev.to / 10 months ago
