Moshe Elisha commented on AVRO-3721:
------------------------------------

Sounds good.

 

In my case, we are using
{code:java}
field.getObjectProps().getOrDefault("propName", someDefault) {code}
so adding a function like 
{code:java}
public V getObjectProp(String key, V defaultValue);{code}
will be best but also 
{code:java}
public V getObjectProp(String key); {code}
will be fine.

 

Perhaps it is best to keep "getObjectProps()" for backward compatibility for 
others.

>             Project: Apache Avro
>          Issue Type: Improvement
>          Components: java
>    Affects Versions: 1.11.1
>            Reporter: Moshe Elisha
>            Priority: Minor
>
> 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.
