Syntax

public class MergePolicySettings : IMergePolicySettings

Properties

ExpungeDeletesAllowed

When expungeDeletes is called, we only merge away a segment if its delete percentage is over this threshold. Default is 10.

Declaration

public int? ExpungeDeletesAllowed { get; set; }

Property Value

Type	Description
int?

FloorSegment

Segments smaller than this are "rounded up" to this size, i.e. treated as equal (floor) size for merge selection. This is to prevent frequent flushing of tiny segments, thus preventing a long tail in the index. Default is 2mb.

Declaration

public string FloorSegment { get; set; }

Property Value

Type	Description
string

MaxMergeAtOnce

Maximum number of segments to be merged at a time during "normal" merging. Default is 10.

Declaration

public int? MaxMergeAtOnce { get; set; }

Property Value

Type	Description
int?

MaxMergeAtOnceExplicit

Maximum number of segments to be merged at a time, during optimize or expungeDeletes. Default is 30.

Declaration

public int? MaxMergeAtOnceExplicit { get; set; }

Property Value

Type	Description
int?

MaxMergedSegment

Maximum sized segment to produce during normal merging (not explicit optimize). This setting is approximate: the estimate of the merged segment size is made by summing sizes of to-be-merged segments (compensating for percent deleted docs). Default is 5gb.

Declaration

public string MaxMergedSegment { get; set; }

Property Value

Type	Description
string

ReclaimDeletesWeight

Controls how aggressively merges that reclaim more deletions are favored. Higher values favor selecting merges that reclaim deletions. A value of 0.0 means deletions don’t impact merge selection. Defaults to 2.0

Declaration

public double? ReclaimDeletesWeight { get; set; }

Property Value

Type	Description
double?

SegmentsPerTier

Sets the allowed number of segments per tier. Smaller values mean more merging but fewer segments. Default is 10. Note, this value needs to be >= than the max_merge_at_once otherwise you’ll force too many merges to occur.

Declaration

public int? SegmentsPerTier { get; set; }

Property Value

Type	Description
int?
