Compute the number of segments that would be needed to cover the totalSize, by climbing up a logarithmically growing staircase of segment tiers.

Plan() will functionally compute a merge plan.

Smaller result score is better.

ToBarChart returns an ASCII rendering of the segments and the plan.

ValidateMergePlannerOptions validates the merge planner options.

MaxSegmentSizeLimit represents the maximum size of a segment, this limit comes with hit-1 optimisation/max encoding limit uint31.

DefaultMergePlanOptions suggests the default options.

ErrMaxSegmentSizeTooLarge is returned when the size of the segment exceeds the MaxSegmentSizeLimit.

SingleSegmentMergePlanOptions helps in creating a single segment index.

A MergePlan is the result of the Plan() API.

The MergePlanOptions is designed to be reusable between planning calls.

A MergeTask represents several segments that should be merged together into a single segment.

A Segment represents the information that the planner needs to calculate segment merging.
