PackedArrayEstimator

public PackedArrayEstimator(CircuitBreaker breaker,
                            IndexNumericFieldData.NumericType type,
                            String fieldName)

メソッドの詳細

bytesPerValue

public long bytesPerValue(org.apache.lucene.util.BytesRef term)

定義:

bytesPerValue インタフェース内 AbstractIndexFieldData.PerValueEstimator

戻り値:

number of bytes per term, based on the NumericValue.requiredBits()

beforeLoad

public org.apache.lucene.index.TermsEnum beforeLoad(org.apache.lucene.index.Terms terms)
                                             throws IOException

インタフェースからコピーされた説明: AbstractIndexFieldData.PerValueEstimator

Execute any pre-loading estimations for the terms. May also optionally wrap a TermsEnum in a RamAccountingTermsEnum which will estimate the memory on a per-term basis.

定義:

beforeLoad インタフェース内 AbstractIndexFieldData.PerValueEstimator

パラメータ:

terms - terms to be estimated

戻り値:

A TermsEnum wrapped in a RamAccountingTermsEnum

例外:

IOException

afterLoad

public void afterLoad(org.apache.lucene.index.TermsEnum termsEnum,
                      long actualUsed)

Adjusts the breaker based on the aggregated value from the RamAccountingTermsEnum

定義:

afterLoad インタフェース内 AbstractIndexFieldData.PerValueEstimator

パラメータ:

termsEnum - terms that were wrapped and loaded

actualUsed - actual field data memory usage

adjustForNoTerms

public void adjustForNoTerms(long actualUsed)

Adjust the breaker when no terms were actually loaded, but the field data takes up space regardless. For instance, when ordinals are used.

パラメータ:

actualUsed - bytes actually used
