BufferingKnnVectorsWriter

abstract class BufferingKnnVectorsWriter : KnnVectorsWriter

Buffers up pending vector value(s) per doc, then flushes when segment flushes. Used for SimpleTextKnnVectorsWriter and for vectors writers before v 9.3 .

Properties

childResources

open val childResources: MutableCollection<Accountable>

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).

Functions

addField

open override fun addField(fieldInfo: FieldInfo): KnnFieldVectorsWriter<*>

Add new field for indexing

expect abstract fun close()

finish

abstract fun finish()

Called once at the end before close

flush

open override fun flush(maxDoc: Int, sortMap: Sorter.DocMap?)

Flush all buffered data on disk *

merge

fun merge(mergeState: MergeState)

Merges the segment vectors for all fields. This default implementation delegates to .mergeOneField, passing a KnnVectorsReader that combines the vector values and ignores deleted documents.

mergeOneField

open override fun mergeOneField(fieldInfo: FieldInfo, mergeState: MergeState)

Write field for merging

ramBytesUsed

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.
