Router Performance Optimization

Caching

In-Memory Caching

Use in-memory LRU cache for generated query plans and automatic persisted queries (APQ).

Go to In-Memory Caching

Distributed Caching

Share Redis-backed cache between router instances.

Go to Distributed Caching

Response Caching

Cache subgraph responses to improve query performance with Redis-backed entity-level caching.

Request Optimization

Traffic Shaping

Tune the performance and reliability of traffic to and from the router.

Go to Traffic Shaping

Query Batching

Improve request-handling throughput with client and subgraph query batching.
