             Summary: [Java[ Add cache to org.apache.avro.JsonProperties.getObjectProps
                 Key: AVRO-3721
                 URL: https://issues.apache.org/jira/browse/AVRO-3721
             Project: Apache Avro
          Issue Type: Improvement
          Components: java
    Affects Versions: 1.11.1
            Reporter: Moshe Elisha


Currently every time you invoke JsonProperties.getObjectProps on same instance, the code loops over the props and creates a new LinkedHashMap and a new UnmodifiableMap.

 

In our use case, we store a Protocol (and the JsonProperties) and access the same instances multiple times.

 

Storing a simple cache "private Map<String, Object> objectProps;" inside JsonProperties will slightly improve performance and memory usage.

objectProps can be lazy initialized in JsonProperties.getObjectProps and reset when "JsonProperties.addProp(String, JsonNode)" is invoked.

 

Thanks.
