> Key: AVRO-4042
> URL: https://issues.apache.org/jira/browse/AVRO-4042
> Project: Apache Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.11.3
> Reporter: Andrew Craig
> Assignee: Oscar Westra van Holthe - Kind
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.12.1
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently, calling `JacksonUtils.toJsonNode(obj)`,
> `JacksonUtils.objectToMap(obj)` or `SchemaBuilder.toJsonNode(obj)` recreate
> at least one new instance of Jackson ObjectMapper each time.
> ObjectMapper is an expensive object to create, but is thread-safe. We can see
> in various other locations within Avro that we reuse the same object, and
> avoid recreation.
> We can perform the same reuse here - and only create the ObjectMapper once.
