----------------------------------------
Summary: Schema Registry client should have a proper caching
mechanism for schema IDs
Key: KAFKA-4579
URL: https://issues.apache.org/jira/browse/KAFKA-4579
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 0.10.1.1
Environment: Kafka version: 10.0.1
JVM: 1.8
OS: Ubuntu 14.01 LTS
Reporter: Justin Manchester
Problem:
Currently the Schema Registry client does not have a proper caching mechanism
for Schema IDs. This regularly leads to users writing producers which do not
reuses schema ID's and which then crash with the following:
Caused by: java.lang.IllegalStateException: Too many schema objects created
Suggested solution: It would better if we had a proper caching mechanism in
place to prevent hard crashes. This often leads to data loss, and the concept
of reusing schema ID's is not always intuitive to users.
