What are the limiations of the SchemaName within AWS Glue Schema Registry? In particular I would like to know:

• What is the maximum character limit for a schema name?
  • I ask because the TopicRecordNameStrategy could potentially lead to very long subject names.
• Does the name have to follow a specific character set (ASCII/UTF8)?
• Can it start with a number?
• Any other limitations with the name which should be known?

For reference: I asked the same question for the confluent schema registry here.
