Enable or Disable to show SQL details.

Print SQL details can help developers debug easier. The details includes: logic SQL, parse context and rewrote actual SQL list. Enable this property will log into log topic: Sharding-Sphere-SQL, log level is INFO. Default: false

EXECUTOR_SIZE

public static final ShardingPropertiesConstant EXECUTOR_SIZE

Worker thread max size.

Execute SQL Statement and PrepareStatement will use this thread pool. One sharding data source will use a independent thread pool, it does not share thread pool even different data source in same JVM. Default: same with CPU cores.

Method Detail

values

public static ShardingPropertiesConstant[] 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 (ShardingPropertiesConstant c : ShardingPropertiesConstant.values())
    System.out.println(c);

Returns:

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

valueOf

public static ShardingPropertiesConstant 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

findByKey

public static ShardingPropertiesConstant findByKey(String key)

Find value via property key.

Parameters:

key - property key

Returns:

value enum, return null if not found
