Field Detail

WRAP_READER_RATIO

public static final org.elasticsearch.common.settings.Setting<java.lang.Double> WRAP_READER_RATIO

Allows tests to wrap an index reader randomly with a given ratio. This is disabled by default ie. 0.0d since reader wrapping is insanely slow if AssertingDirectoryReader is used.

DISABLE_FLUSH_ON_CLOSE

public static final org.elasticsearch.common.settings.Setting<java.lang.Boolean> DISABLE_FLUSH_ON_CLOSE

Allows tests to prevent an engine from being flushed on close ie. to test translog recovery...
