Element Detail

name

public abstract String name

Group index name.

Returns:

Name.

inlineSize

public abstract int inlineSize

Index inline size in bytes. When enabled part of indexed value will be placed directly to index pages, thus minimizing data page accesses, thus increasing query performance.

Allowed values:

• -1 (default) - determine inline size automatically (see below)
• 0 - index inline is disabled (not recommended)
• positive value - fixed index inline

When set to -1, Ignite will try to detect inline size automatically. It will be no more than CacheConfiguration.getSqlIndexMaxInlineSize(). Index inline will be enabled for all fixed-length types, but will not be enabled for String.

Returns:

Index inline size in bytes.

Default:

-1
