API Latency Benchmark

Learn about Reltio’s baseline API performance and the key factors that affect it.


The Reltio platform powers complex implementations. As you plan your implementation, it’s important to predict the impact of your implementation on performance. This article helps you predict performance by providing:
  • Baseline latency for the seven API types mentioned in Table 1.
  • Factors that affect latency for each API type.

Baseline API Latency and Parameters

We calculated the latency API types with the following assumptions:
  • No Lifecycle Actions (LCA) are used in the tenant
  • Simple address cleanser is used
  • No ordering and scoring is used in GET requests
  • No queries to the data history storage as part of the GET calls
  • Transitive matching isn’t enabled (parameter deep = 1)
  • URI only flag is set to true for the POST API
The following table summarizes the baseline (average) latency you can expect:
Table 1. Latency Details
API Call Description Baseline Latency, ms
POST Entities API Latency (POST /entities) Load data into tenant 130
GET Entities API Latency (GET /entities) Get entities using a filter 47
GET Entity ID API Latency ((GET /entity/{id})) Find entity by ID 51
GET Entities Matches API Latency (GET /entity/_matches) Find all matches for an entity 97
GET Entities Tree API Latency (GET /entity/{id}_tree) Discover tree 260
GET Entities Hops API Latency (GET /entity/{id}_hops) Get Hops 85
POST Entities Connections API Latency (POST /entities{id}/_connections) Find Connections 227
We calculated the latency based on the following baseline parameters. Changes in these parameters will change the API latency.
