Enum Constant Detail

COLUMNS_DIFF

public static final PostgresConnectorConfig.SchemaRefreshMode COLUMNS_DIFF

Refresh the in-memory schema cache whenever there is a discrepancy between it and the schema derived from the incoming message.

COLUMNS_DIFF_EXCLUDE_UNCHANGED_TOAST

public static final PostgresConnectorConfig.SchemaRefreshMode COLUMNS_DIFF_EXCLUDE_UNCHANGED_TOAST

Refresh the in-memory schema cache if there is a discrepancy between it and the schema derived from the incoming message, unless TOASTable data can account for the discrepancy. This setting can improve connector performance significantly if there are frequently-updated tables that have TOASTed data that are rarely part of these updates. However, it is possible for the in-memory schema to become outdated if TOASTable columns are dropped from the table.

Method Detail

values

public static PostgresConnectorConfig.SchemaRefreshMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PostgresConnectorConfig.SchemaRefreshMode c : PostgresConnectorConfig.SchemaRefreshMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PostgresConnectorConfig.SchemaRefreshMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getValue

public String getValue()

Specified by:

getValue in interface EnumeratedValue

parse

public static PostgresConnectorConfig.SchemaRefreshMode parse(String value)

Determine if the supplied value is one of the predefined options.

Parameters:

value - the configuration property value; may not be null

Returns:

the matching option, or null if no match is found
