Build sst_dump:
sudo apt-get install libgflags-dev
scripts/du_rocksdb_fast/build.sh
Run the tool:
scripts/du_rocksdb_fast/run.py --rocksdb-data=~/.near/data
If you already have a built sst_dump tool you can skip the first step and specify the path to sst_dump:
scripts/du_rocksdb_fast/run.py --rocksdb-data=~/.near/data --sst-dump=~/rocksdb/build/tools/sst_dump
