Class DenseVectorBlockLoader<B extends BlockLoader.Builder>

java.lang.Object

org.elasticsearch.index.mapper.blockloader.docvalues.BlockDocValuesReader.DocValuesBlockLoader

org.elasticsearch.index.mapper.blockloader.docvalues.DenseVectorBlockLoader<B>

Type Parameters:

B - The type of builder used (FloatBuilder for vectors, DoubleBuilder for scores, etc.)

All Implemented Interfaces:

Field Details

ESTIMATED_SIZE

public static final long ESTIMATED_SIZE

Circuit breaker space reserved for each reader. Most of the data is held off heap and the reader itself is quite small. We've measured it at 600 bytes in heap dumps. 1kb is an overestimate.
