Constructor Details

ScalarQuantizationCompression

public ScalarQuantizationCompression(String compressionName)

Creates an instance of ScalarQuantizationCompression class.

Parameters:

compressionName - the compressionName value to set.

Method Details

fromJson

public static ScalarQuantizationCompression fromJson(JsonReader jsonReader)

Reads an instance of ScalarQuantizationCompression from the JsonReader.

Parameters:

jsonReader - The JsonReader being read.

Returns:

An instance of ScalarQuantizationCompression if the JsonReader was pointing to an instance of it, or null if it was pointing to JSON null.

Throws:

IOException

- If the deserialized JSON object was missing any required properties.

getKind

public VectorSearchCompressionKind getKind()

Get the kind property: Type of VectorSearchCompression.

Overrides:

ScalarQuantizationCompression.getKind()

Returns:

the kind value.

getParameters

public ScalarQuantizationParameters getParameters()

Get the parameters property: Contains the parameters specific to Scalar Quantization.

Returns:

the parameters value.

setParameters

public ScalarQuantizationCompression setParameters(ScalarQuantizationParameters parameters)

Set the parameters property: Contains the parameters specific to Scalar Quantization.

Parameters:

parameters - the parameters value to set.

Returns:

the ScalarQuantizationCompression object itself.

setRescoringOptions

public ScalarQuantizationCompression setRescoringOptions(RescoringOptions rescoringOptions)

Set the rescoringOptions property: Contains the options for rescoring.

Overrides:

ScalarQuantizationCompression.setRescoringOptions(RescoringOptions rescoringOptions)

Parameters:

rescoringOptions

setTruncationDimension

public ScalarQuantizationCompression setTruncationDimension(Integer truncationDimension)

Set the truncationDimension property: The number of dimensions to truncate the vectors to. Truncating the vectors reduces the size of the vectors and the amount of data that needs to be transferred during search. This can save storage cost and improve search performance at the expense of recall. It should be only used for embeddings trained with Matryoshka Representation Learning (MRL) such as OpenAI text-embedding-3-large (small). The default value is null, which means no truncation.

Overrides:

ScalarQuantizationCompression.setTruncationDimension(Integer truncationDimension)

Parameters:

truncationDimension

toJson

public JsonWriter toJson(JsonWriter jsonWriter)

Overrides:

ScalarQuantizationCompression.toJson(JsonWriter jsonWriter)

Parameters:

jsonWriter

Throws:
