Add contribute to the block cache option to the iterators.

[koculu]

Summary

The CreateIterator method now includes a contributeToTheBlockCache flag, giving you control over whether the iterator’s scan should impact the block cache:

IZoneTreeIterator<TKey, TValue> CreateIterator(
    IteratorType iteratorType = IteratorType.AutoRefresh,
    bool includeDeletedRecords = false,
    bool contributeToTheBlockCache = false);

New Flag: contributeToTheBlockCache

• contributeToTheBlockCache: When set to true, the blocks read by the iterator will be added to the block cache. When set to false (default), the iterator’s scan will not affect the block cache.

Example Usage:

using var iterator = zoneTree.CreateIterator(contributeToTheBlockCache: true);
while(iterator.Next()) {
    var key = iterator.CurrentKey;
    var value = iterator.CurrentValue;
}
