Usage:
default is lmdb for blockchain branch:
$ make release
same as:
$ DATABASE=lmdb make release
for original in-memory implementation:
$ DATABASE=memory make release
COMMITS:
- Add compile-time support for both db implementations: in-memory and LMDB
NOTE:
The default should be changed to lmdb when this is merged upstream
unless we're 100% sure the LMDB implementation is ready.
