Here gather the long-term plans of Pegasus.
Shrink the size of Pegasus kernel
Pegasus targets to be a simple, robust key-value database with stable&predictable latency. To achieve the performance requirement, we use C++ for the "kernel", i.e MetaServer and ReplicaServer.
However, C++ is notorious for its inefficiency (in development) and high learning curve, which eventually leads to a high contribution barrier.
We expect the C++ codebase, including the functionalities of Pegasus kernel, can be simpler, smaller, and more stable.
Build an ecosystem around Pegasus
As Pegasus grows, we have learned that it's impossible to maintain a monolithic system bundled with sophisticated features. So we need an ecosystem with a variety of useful tools, controllers, surrounding the kernel and altogether manages the clusters more intelligently.
Improve the stability of Pegasus
Performance is usually the main reason people choose Pegasus,
