Key-Value Map in APIGEE for Efficient API Management
In this blog, we will learn about the Key-Value Map in APIGEE for Efficient API Management.
Apigee is a premier platform for creating, securing, managing, and analyzing APIs, where efficient data storage and retrieval are crucial for optimal performance and scalability. One feature that addresses this need is Key-Value Maps (KVM), which allows developers to flexibly store and quickly access frequently used data. This blog explores KVM, its benefits, and effective implementation strategies in Apigee.
Key-Value Map(KVM) is a straightforward data storage model that associates keys with values. In Apigee, KVM acts as a mechanism for persisting key-value pairs accessible through API calls. It is particularly useful for storing configuration settings, tokens, user sessions, or any data represented as key-value pairs.
Consider an API that provides current exchange rates between currencies. Instead of hardcoding these rates, they can be stored in a KVM and retrieved based on user requests. When a user queries the exchange rate for two currencies, the API checks the KVM for the rate. If found, it returns the rate; if not, an error message is sent, facilitating efficient currency management.
Characteristics of KVM
KVM consists of unique keys paired with corresponding values, allowing for easy storage and retrieval. It can handle numerous key-value pairs, making it suitable for dynamic data requirements. KVM supports various data types, enabling the storage of JSON, strings, and binary data, accessible or modifiable at runtime through apigee’s policies and API calls
KVM Features
- KVMs offer dynamic storage for real-time access and updates, ideal for configurations and caching.
- They can be created at different organizations, environments, or API proxies for flexibility.
- KVMs also support encrypted storage for sensitive data and facilitate real-time access during API requests, while TTL options help manage data expiry and ensure information remains current.
Adding KVM policy to the flow:
Key-value maps (KVM) in Apigee enhance API management by providing dynamic storage, flexible scope options, and secure data handling. They enable seamless data updates and include TTL options to maintain relevance, optimize API performance, and improve user experience.
