Method Details

initKeySchema

SchemaEntry initKeySchema(String storeName,
 String schemaStr)

Set up key schema for the given store

addValueSchema

default SchemaEntry addValueSchema(String storeName,
 String schemaStr)

Add a new value schema for the given store

addValueSchema

SchemaEntry addValueSchema(String storeName,
 String schemaStr,
 DirectionalSchemaCompatibilityType expectedCompatibilityType)

Add a new value schema for the given store

addValueSchema

SchemaEntry addValueSchema(String storeName,
 String schemaStr,
 int schemaId)

Add a new value schema for the given store by specifying schema id. This API is mostly intended to be used in cross-colo mode. When there are multiple colos, we'd like to have consistent value id across colos, so that deserializer can work properly while reading records. Caller should figure out the schema id number by themselves. TODO: Might want to remove it from the interface and make it invisible from the outside

addDerivedSchema

DerivedSchemaEntry addDerivedSchema(String storeName,
 String schemaStr,
 int valueSchemaId)

Add a new derived schema for the given store and value schema id

addDerivedSchema

DerivedSchemaEntry addDerivedSchema(String storeName,
 String schemaStr,
 int valueSchemaId,
 int derivedSchemaId)

Add a new derived schema for the given store by specifying derived schema id. Mostly used in cross-colo mode.

removeDerivedSchema

DerivedSchemaEntry removeDerivedSchema(String storeName,
 int valueSchemaId,
 int derivedSchemaId)

Remove an existing derived schema

Returns:

the derived schema that is deleted or null if the schema doesn't exist

preCheckValueSchemaAndGetNextAvailableId

int preCheckValueSchemaAndGetNextAvailableId(String storeName,
 String valueSchemaStr,
 DirectionalSchemaCompatibilityType expectedCompatibilityType)

preCheckDerivedSchemaAndGetNextAvailableId

int preCheckDerivedSchemaAndGetNextAvailableId(String storeName,
 int valueSchemaId,
 String derivedSchemaStr)

addReplicationMetadataSchema

RmdSchemaEntry addReplicationMetadataSchema(String storeName,
 int valueSchemaId,
 String replicationMetadataSchemaStr,
 int replicationMetadataVersionId)

removeValueSchema

void removeValueSchema(String storeName,
 int schemaID)
