>                 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
>            Priority: Minor
>              Labels: pull-request-available
>          Time Spent: 0.5h
>  Remaining Estimate: 0h
>
> 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.
