Methods in org.apache.sysds.runtime.compress that return CompressionSettingsBuilder

Modifier and Type	Method	Description
CompressionSettingsBuilder	CompressionSettingsBuilder.addValidCompression(AColGroup.CompressionType cp)	Add a single valid compression type to the EnumSet of valid compressions.
CompressionSettingsBuilder	CompressionSettingsBuilder.clearValidCompression()	Clear all the compression types allowed in the compression.
CompressionSettingsBuilder	CompressionSettingsBuilder.copySettings(CompressionSettings that)	Copy the settings from another CompressionSettings Builder, modifies this, not that.
CompressionSettingsBuilder	CompressionSettingsBuilder.setAllowSharedDictionary(boolean allowSharedDictionary)	Allow the Dictionaries to be shared between different column groups.
CompressionSettingsBuilder	CompressionSettingsBuilder.setCoCodePercentage(double coCodePercentage)	Set the coCode percentage, the effect is different based on the coCoding strategy, but the general effect is that higher values results in more coCoding while lower values result in less.
CompressionSettingsBuilder	CompressionSettingsBuilder.setColumnPartitioner(CoCoderFactory.PartitionerType columnPartitioner)	Set the type of CoCoding Partitioner type to use for combining columns together.
CompressionSettingsBuilder	CompressionSettingsBuilder.setCostType(CostEstimatorFactory.CostType costType)	Set the cost type used for estimating the cost of column groups default is memory based.
CompressionSettingsBuilder	CompressionSettingsBuilder.setEstimationType(SampleEstimatorFactory.EstimationType estimationType)	Set the estimation type used for the sampled estimates.
CompressionSettingsBuilder	CompressionSettingsBuilder.setIsInSparkInstruction()	Inform the compression that it is executed in a spark instruction.
CompressionSettingsBuilder	CompressionSettingsBuilder.setLossy(boolean lossy)	Set the Compression to use Lossy compression.
CompressionSettingsBuilder	CompressionSettingsBuilder.setMaxColGroupCoCode(int maxColGroupCoCode)	Set the maximum number of columns to CoCode together in the CoCoding strategy.
CompressionSettingsBuilder	CompressionSettingsBuilder.setMaxSampleSize(int maxSampleSize)	Set the maximum sample size to extract from a given matrix, this overrules the sample percentage if the sample percentage extracted is higher than this maximum bound.
CompressionSettingsBuilder	CompressionSettingsBuilder.setMinimumCompressionRatio(double ratio)	Set the minimum compression ratio to be achieved by the compression.
CompressionSettingsBuilder	CompressionSettingsBuilder.setMinimumSampleSize(int minimumSampleSize)	Set the minimum sample size to extract from a given matrix, this overrules the sample percentage if the sample percentage extracted is lower than this minimum bound.
CompressionSettingsBuilder	CompressionSettingsBuilder.setPreferDeltaEncoding(boolean preferDeltaEncoding)	Set whether to prefer delta encoding during compression estimation.
CompressionSettingsBuilder	CompressionSettingsBuilder.setSamplingRatio(double samplingRatio)	Set the sampling ratio in percent to sample the input matrix.
CompressionSettingsBuilder	CompressionSettingsBuilder.setScaleFactor(double[] scaleFactors)	Sets the scale factors for compression, enabling quantization-fused compression.
CompressionSettingsBuilder	CompressionSettingsBuilder.setSDCSortType(InsertionSorterFactory.SORT_TYPE sdcSortType)	Set the sort type to use.
CompressionSettingsBuilder	CompressionSettingsBuilder.setSeed(int seed)	Set the seed for the compression operation.
CompressionSettingsBuilder	CompressionSettingsBuilder.setSortValuesByLength(boolean sortValuesByLength)	Set the sortValuesByLength flag.
CompressionSettingsBuilder	CompressionSettingsBuilder.setTransposeInput(String transposeInput)	Specify if the input matrix should be transposed before compression.
CompressionSettingsBuilder	CompressionSettingsBuilder.setValidCompressions(EnumSet<AColGroup.CompressionType> validCompressions)	Set the valid compression strategies used for the compression.
