Class ConfigDef

java.lang.Object

org.apache.kafka.common.config.ConfigDef

public class ConfigDef
extends Object

This class is used for specifying the set of expected configurations. For each configuration, you can specify the name, the type, the default value, the documentation, the group information, the order in the group, the width of the configuration value and the name suitable for display in the UI. You can provide special validation logic used for single configuration validation by overriding ConfigDef.Validator. Moreover, you can specify the dependents of a configuration. The valid values and visibility of a configuration may change according to the values of other configurations. You can override ConfigDef.Recommender to get valid values and set visibility of a configuration given the current configuration values.

To use the class:

 ConfigDef defs = new ConfigDef();

 defs.define("config_with_default", Type.STRING, "default string value", "Configuration with default value.");
 defs.define("config_with_validator", Type.INT, 42, Range.atLeast(0), "Configuration with user provided validator.");
 defs.define("config_with_dependents", Type.INT, "Configuration with dependents.", "group", 1, "Config With Dependents", Arrays.asList("config_with_default","config_with_validator"));

 Map<String, String> props = new HashMap<>();
 props.put("config_with_default", "some value");
 props.put("config_with_dependents", "some other value");

 Map<String, Object> configs = defs.parse(props);
 // will return "some value"
 String someConfig = (String) configs.get("config_with_default");
 // will return default value of 42
 int anotherConfig = (Integer) configs.get("config_with_validator");

 To validate the full configuration, use:
 List<Config> configs = defs.validate(props);
 The Config contains updated configuration information given the current configuration values.
 

This class can be used standalone or in combination with AbstractConfig which provides some additional functionality for accessing configs.

defineBalancerConfigs

public ConfigDef defineBalancerConfigs()

configKeys

public Map<String,ConfigDef.ConfigKey> configKeys()

Get the configuration keys

Returns:

a map containing all configuration keys

groups

Get the groups for the configuration

Returns:

a list of group names

withClientSslSupport

public ConfigDef withClientSslSupport()

Add standard SSL client configuration options.

Returns:

this

parse

public Map<String,Object> parse(Map<?,?> props)

Parse and validate configs against this configuration definition. The input is a map of configs. It is expected that the keys of the map are strings, but the values can either be strings or they may already be of the appropriate type (int, string, etc). This will work equally well with either java.util.Properties instances or a programmatically constructed map.

Parameters:

props - The configs to parse and validate.

Returns:

Parsed and validated configs. The key will be the config name and the value will be the value parsed into the appropriate type (int, string, etc).

validate

public List<ConfigValue> validate(Map<String,String> props)

Validate the current configuration values with the configuration definition.

Parameters:

props - the current configuration values

Returns:

List of Config, each Config contains the updated configuration information given the current configuration values.

validateAll

public Map<String,ConfigValue> validateAll(Map<String,String> props)

parseType

public static Object parseType(String name,
                               Object value,
                               ConfigDef.Type type)

Parse a value according to its expected type.

Parameters:

name - The config name

value - The config value

type - The expected type

Returns:

The parsed object

convertToString

public static String convertToString(Object parsedValue,
                                     ConfigDef.Type type)

convertToStringMapWithPasswordValues

public static Map<String,String> convertToStringMapWithPasswordValues(Map<String,?> configs)

Converts a map of config (key, value) pairs to a map of strings where each value is converted to a string. This method should be used with care since it stores actual password values to String. Values from this map should never be used in log entries.

toHtmlTable

public String toHtmlTable()

toHtmlTable

public String toHtmlTable(Map<String,String> dynamicUpdateModes)

Converts this config into an HTML table that can be embedded into docs. If dynamicUpdateModes is non-empty, a "Dynamic Update Mode" column will be included n the table with the value of the update mode. Default mode is "read-only".

Parameters:
