Database Engine
===============
You can choose from RocksDB, LevelDB or LMDB to store transaction
information on disk. Currently, the fastest seems to be RocksDB with
LevelDB being slightly slower. LMDB is slowest but that is because the
code needs reworking to be better usable with LMDB.
You can choose from LevelDB and RocksDB to store transaction
information on disk. The time taken and DB size is not significantly
different. We tried to support LMDB but its history write performance
was much worse.
You will need to install one of:
+ `plyvel <https://plyvel.readthedocs.io/en/latest/installation.html>`_ for LevelDB
+ `pyrocksdb <http://pyrocksdb.readthedocs.io/en/v0.4/installation.html>`_ for RocksDB
+ `lmdb <https://lmdb.readthedocs.io/en/release/#installation-unix>`_ for LMDB
