Fabian Reinartz 62b8ded0a5 Rename iterator value getters to At() 2017-01-02 13:33:06 +01:00
Fabian Reinartz 5d75a3dc7b Add basic compaction
This adds a basic compactor that will merge two persisted blocks into
one. It simply fully rewrites the index and concatenates the chunk
lists.

It just writes into the current working dir and doesn't properly handle
which blocks to compact for now.

Fabian Reinartz fa181a34c1 chunks: cleanup anything but xor encoding
xor encoding is fast enough for our purposes and provides
very good compression.
We remove all other ones that partially don't support floats
for the sake of simplicity.
