Near Protocol’s Remote Procedure Call (RPC) interface is the contact point through which dApps communicate with the NEAR blockchain, a key component in its architecture. Developers’ main task in developing DAps is to eliminate NEAR RPC ideally. The following will trace out some of the most vital areas of development to upgrade the speed of RPC NEAR requests and ensure that applications are highly effective and NEAR RPC nodes are considered in this process.
What is NEAR RPC?
We will briefly present NEAR RPC and how it works, then discuss the optimization techniques. NEAR RPC offers an API for dApps to call for data from the NEAR blockchain without communicating with the nodes over HTTP or WebSocket. This kind of solicitation can be illustrated by performing actions, including reading blockchain data, executing intelligent contract functions, and sending transactions. Near RPC nodes execute polling and provide services between dApps and the blockchain, receiving commands and further passing data. Consider the RAC structure shown below as an illustration.
Optimization Techniques for NEAR RPC
- Batching Requests: Instead of asking multiple RPC calls, batch-related requests are split into one. With this in place, the overall network usage is reduced, making it faster and more responsive. For instance, instead of making intelligent contracts separately, combine the various requests on one single list and send the whole list simultaneously.
- Caching Responses: Make caching of frequently accessed data happen in the local area of your app, which would act as a normalization process, thus storing it locally. By exploiting RPC calls caching reactions, you will avoid repetitive requests and improve response times. At the same time, it is essential to ensure that the current state of the blockchain in the cache does not differ from the original one and not to provide outdated info to healthcare professionals.
- Optimizing Query Parameters: Be aware of the types of NEAR RPC requests used throughout the code and optimize the parameters for performance. Development of this could, for example, be based upon the limitation of types of queries and pagination to gradually retrieve the large datasets and filter the data at the source if possible, avoiding needless processing methods.
- Asynchronous Processing: Apply asynchronous programming mechanisms to simultaneously parallelize NEAR RPC queries and other computing processes in your dApp. A high number of concurrent executions prevents the delay of process flow. Thus, a good user experience is made.
- Monitoring and Profiling: Continuously assess NEAR RPC calls as they are within the implementation of your dApp using appropriate tools and metrics. Monitor performance metrics, including response times, error rates, and network latency, to troubleshoot and enhance potential bottlings and bottlenecks. Profile-based tools may help break down a system into particular functions or queries that take away opposite resources.
Role of NEAR RPC Nodes in Performance Optimization
NEAR RPC nodes built closer to the RPC nodes are in charge of maximizing their efficiency. These nodes often act as the interchange between dApp and NEAR blockchain, where incoming RPC requests are handled, and operations are carried out on behalf of the user. To ensure optimal performance, developers should consider the following aspects related to NEAR RPC nodes: To ensure optimal performance, developers should consider the following aspects related to NEAR RPC nodes:
- Node Configuration: Instill the NEAR RPC nodes with resources and bandwidth beyond sufficient to cope with incoming demands faultlessly. Take precautions so that nodes are correctly tuned and match precisely the workload of your dApp. Network latencies, bright contract complexity, and many other factors must be considered.
- Load Balancing: Provide a load balance to incoming RPC requests via multiple NEAR RPC nodes using suitable load balancing techniques. Doing so makes traffic better distributed between peers, and dApp users will enjoy fast and reliable performance.
- Network Connectivity: Select NEAR RPC node providers that operate with top-notch network connectivity and low latency and prioritize an improved user experience about the response time issue. Evaluate hiring node container providers based on their location and the available network infrastructure.
By implementing these best practices and leveraging open-sourced NEAR RPC nodes, developers can have a higher speed of the NEAR RPC calls and, thus, develop applications with high performances and a seamless user experience.
