# NOTE: the MS MARCO v2 documents have this really neat quality that they contain the offset
# position in the source file: <https://microsoft.github.io/msmarco/TREC-Deep-Learning.html>.
# Unfortunately, it points to the position in the *uncompressed* file, so for this to work, we'd
# need to decompress the source files, inflating the size ~3.3x. The options would be to:
# 1) Always de-compress the source files, costing everybody ~3.3x the storage. Ouch.
# 2) De-compress the source files the first time that the docstore is requested. This would
# only cost the users who use the docstore 3.3x, but increases the complexity of the
# iteration code to handle both compressed and non-compressed versions. Would also need code
# to handle stuff like fancy slicing, which wouldn't be trivial. Would we also keep
# the original source file around? If so, it actually ends up being 4.3x.
# 3) Build a PickleLz4FullStore on demand, as normal. This would only cost the users who use
# the docstore ~2.7x (accounting for worse lz4 compression rate and keeping around original
# copy of the data), but is also slightly slower because of the O(log n) position lookups and
# decompression. (This may be offset because pickle parsing is faster than json though.)
# It also reduces the complexity of the code, as it does not require a new docstore
# implementation for this dataset, and is just doing the normal procedure.
