> Priority: Major

> The specs only has added bloom_filter_offset to locate the bloom filter. The
> reader cannot load the bloom filter in a single shot until it parses the
> bloom filter header to get the total size.
> This issue proposes to add an optional bloom_filter_length field to track the
> size of bloom filter to facilitate I/O scheduling.
