public CacheOptions(long hole_size_limit, long range_size_limit, bool lazy, long prefetch_limit = 0)

Parameters

hole_size_limit long

range_size_limit long

lazy bool

prefetch_limit long

Fields

hole_size_limit

The maximum distance in bytes between two consecutive ranges; beyond this value, ranges are not combined

public long hole_size_limit

Field Value

long

lazy

A lazy cache does not perform any I/O until requested. lazy = false: request all byte ranges when PreBuffer or WillNeed is called. lazy = True, prefetch_limit = 0: request merged byte ranges only after the reader needs them. lazy = True, prefetch_limit = k: prefetch up to k merged byte ranges ahead of the range that is currently being read.

public bool lazy

Field Value

bool

prefetch_limit

The maximum number of ranges to be prefetched. This is only used for lazy cache to asynchronously read some ranges after reading the target range.

public long prefetch_limit

Field Value

long

range_size_limit

The maximum size in bytes of a combined range; if combining two consecutive ranges would produce a range of a size greater than this, they are not combined

public long range_size_limit

Field Value

long
