Method Detail

getPayloadType

protected String getPayloadType()

Description copied from class: SQLMetadataConnector

SQL type to use for payload data (e.g. JSON blobs). Must be a binary type, which values can be accessed using ResultSet.getBytes() The resulting string will be interpolated into the table creation statement, e.g. CREATE TABLE druid_table ( payload NOT NULL, ... )

Overrides:

getPayloadType in class SQLMetadataConnector

Returns:

String representing the SQL type

getSerialType

protected String getSerialType()

Description copied from class: SQLMetadataConnector

Auto-incrementing SQL type to use for IDs Must be an integer type, which values will be automatically set by the database The resulting string will be interpolated into the table creation statement, e.g. CREATE TABLE druid_table ( id NOT NULL, ... )

Specified by:

getSerialType in class SQLMetadataConnector

Returns:

String representing the SQL type and auto-increment statement
