In particular will it exceed the > 32bit Long limit on Windows? A reftable file is organized as a sequence of blocks. Each block has max size 2^24, and the zlib compression is done per-block. So zlib should not introduce a new 4G limit. The intra-file offsets for the blocks themselves are encoded either as varint (index values) or as uint64 (file footer), so reftable files beyond 4G should be no problem. -- Han-Wen Nienhuys - Google Munich I work 80%.
