Christophe Le Saec commented on AVRO-3721:
------------------------------------------
What about using [Vavr collections|https://docs.vavr.io/#_sorted_set], that are
naturally immutable ? especially
[LinkedHashMap|https://www.javadoc.io/static/io.vavr/vavr/0.10.4/io/vavr/collection/LinkedHashMap.html]
class that preserve insert order.
> [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
> 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.
