Examples of VersionedSchemaSet

com.linkedin.databus2.schemas.VersionedSchemaSet
VersionedSchemaSet is a repository for schemas. Schemas may be retrieved either by SchemaId or by a name-version pair (aka VersionedSchemaId). "name" is usually name of the source (table). TODO It seems to be redundant to keep the "name" in the key as well as the value. One of these should be replaced with SchemaId. "Borrowed" largely from com.linkedin.avro.SchemaSet

    LOG.info("Schema = " + schemaRegistry.fetchLatestSchemaBySourceName(_queryStaticConfig.getSourceName()));


    _schema = Schema.parse(schemaRegistry.fetchLatestSchemaBySourceName(_queryStaticConfig.getSourceName()));
    VersionedSchema vs = new VersionedSchema(_schema.getFullName(), (short)1, _schema, null);


    VersionedSchemaSet schemaSet = new VersionedSchemaSet();
    schemaSet.add(vs);
    _decoder = new DbusEventAvroDecoder(schemaSet);
