Enum Constant Summary

Enum Constants

Enum Constant and Description
PARQUET_1_0 Enable only pre-2.2 Parquet format features when writing This setting is useful for maximum compatibility with legacy readers.
PARQUET_2_0 DEPRECATED: Enable Parquet format 2.6 features This misleadingly named enum value is roughly similar to PARQUET_2_6.
PARQUET_2_4 Enable Parquet format 2.4 and earlier features when writing This enables UINT32 as well as logical types which don't have a corresponding converted type.
PARQUET_2_6 Enable Parquet format 2.6 and earlier features when writing This enables the NANOS time unit in addition to the PARQUET_2_4 features.
PARQUET_2_LATEST Enable latest Parquet format 2.x features This value is equal to the greatest 2.x version supported by this library.

Enum Constant Detail

PARQUET_1_0

public static final ParquetVersion.type PARQUET_1_0

Enable only pre-2.2 Parquet format features when writing This setting is useful for maximum compatibility with legacy readers. Note that logical types may still be emitted, as long they have a corresponding converted type.

PARQUET_2_0

public static final ParquetVersion.type PARQUET_2_0

DEPRECATED: Enable Parquet format 2.6 features This misleadingly named enum value is roughly similar to PARQUET_2_6.

PARQUET_2_4

public static final ParquetVersion.type PARQUET_2_4

Enable Parquet format 2.4 and earlier features when writing This enables UINT32 as well as logical types which don't have a corresponding converted type. Note: Parquet format 2.4.0 was released in October 2017.

PARQUET_2_6

public static final ParquetVersion.type PARQUET_2_6

Enable Parquet format 2.6 and earlier features when writing This enables the NANOS time unit in addition to the PARQUET_2_4 features. Note: Parquet format 2.6.0 was released in September 2018.

PARQUET_2_LATEST

public static final ParquetVersion.type PARQUET_2_LATEST

Enable latest Parquet format 2.x features This value is equal to the greatest 2.x version supported by this library.

Method Detail

values

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

Returns:

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

valueOf

public static ParquetVersion.type 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

intern

public ParquetVersion.type intern()

toString

public String toString()

Overrides:

toString in class Enum<ParquetVersion.type>
