Enum Constant Summary

Enum Constants

Enum Constant	Description
CUSTOM	Custom mode allows you to customize buffer size and queue to balance resource utilization and desired performance.
PERFORMANCE	Performance mode provides best performance at the cost of more CPU and much much more memory usage - almost everything is loaded into working memory.
RESOURCE_EFFICIENT	Resource-efficient mode provides reasonable performance with least CPU and memory usage, which makes it ideal as default mode.

Method Summary

Modifier and Type	Method	Description
static ClickHouseBufferingMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static ClickHouseBufferingMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

RESOURCE_EFFICIENT

public static final ClickHouseBufferingMode RESOURCE_EFFICIENT

Resource-efficient mode provides reasonable performance with least CPU and memory usage, which makes it ideal as default mode. Only buffer size is considered in this mode, no queue is used for buffering.

CUSTOM

public static final ClickHouseBufferingMode CUSTOM

Custom mode allows you to customize buffer size and queue to balance resource utilization and desired performance.

PERFORMANCE

public static final ClickHouseBufferingMode PERFORMANCE

Performance mode provides best performance at the cost of more CPU and much much more memory usage - almost everything is loaded into working memory.

Method Detail

values

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

Returns:

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

valueOf

public static ClickHouseBufferingMode 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
