# 100 chunks of 500 state groups per night. Progress is stored in the
# state_compressor_* tables, so each run continues where the last one stopped.
# Every state group is rewritten in its own transaction, after the compressed
# state is checked against the original; a chunk that would not shrink is skipped.
