Detailed Description

Representation of column storage attributes.

Member Enumeration Documentation

EncodingType

enum kudu::client::KuduColumnStorageAttributes::EncodingType

Column encoding types.

Enumerator
GROUP_VARINT	Deprecated: GROUP_VARINT is not supported for valid types, and will fall back to another encoding on the server side.

Constructor & Destructor Documentation

KuduColumnStorageAttributes()

inlineexplicit

Deprecated:

This constructor is deprecated for external use, and will be made private in a future release.

Todo:

Make this constructor private.

Parameters

[in]	encoding	Encoding type for the column storage.
[in]	compression	Compression type for the column storage.
[in]	block_size	Block size (in bytes, uncompressed data) for the column storage.
