Syntax
public class JsonDeserializer<T> : AsyncDeserializer<T, JsonSchema>, IAsyncDeserializer<T> where T : class
Type Parameters
Name Description
T
Remarks

Serialization format: byte 0: A magic byte that identifies this as a message with Confluent Platform framing. bytes 1-4: Unique global id of the JSON schema associated with the data (as registered in Confluent Schema Registry), big endian. following bytes: The JSON data (utf8)

Internally, uses Newtonsoft.Json for deserialization. Currently, no explicit validation of the data is done against the schema stored in Schema Registry.

Note: Off-the-shelf libraries do not yet exist to enable integration of System.Text.Json and JSON Schema, so this is not yet supported by the deserializer.

Constructors

JsonDeserializer(ISchemaRegistryClient, Schema, IEnumerable<KeyValuePair<string, string>>, JsonSchemaGeneratorSettings)

Initialize a new JsonDeserializer instance with a given Schema.

Declaration
public JsonDeserializer(ISchemaRegistryClient schemaRegistryClient, Schema schema, IEnumerable<KeyValuePair<string, string>> config = null, JsonSchemaGeneratorSettings jsonSchemaGeneratorSettings = null)
Parameters
Type Name Description
ISchemaRegistryClient schemaRegistryClient

Confluent Schema Registry client instance.
Schema schema

Schema to use for validation, used when external schema references are present in the schema. Populate the References list of the schema for the same. Assuming the referenced schemas have already been registered in the registry.
IEnumerable<KeyValuePair<string, string>> config

Deserializer configuration properties (refer to JsonDeserializerConfig).
JsonSchemaGeneratorSettings jsonSchemaGeneratorSettings

JSON schema generator settings.

public JsonDeserializer(ISchemaRegistryClient schemaRegistryClient, JsonDeserializerConfig config, JsonSchemaGeneratorSettings jsonSchemaGeneratorSettings = null, RuleRegistry ruleRegistry = null)
Parameters
Type Name Description
ISchemaRegistryClient schemaRegistryClient
JsonDeserializerConfig config
JsonSchemaGeneratorSettings jsonSchemaGeneratorSettings
RuleRegistry ruleRegistry

JsonDeserializer(ISchemaRegistryClient, IEnumerable<KeyValuePair<string, string>>, JsonSchemaGeneratorSettings)

Parameters
Type Name Description
IEnumerable<KeyValuePair<string, string>> config

Deserializer configuration properties (refer to JsonDeserializerConfig).
