From #2 (comment) :
We should use RocksDB instead via the Erlang bindings.
I see there are two RocksDB bindings on hex:
- https://hex.pm/packages/erocksdb i.e. https://github.com/leo-project/erocksdb
- https://hex.pm/packages/rocksdb i.e. https://gitlab.com/barrel-db/erlang-rocksdb
from aeternity.
I am writing here my state on this so far. Next steps are:
- Summarize differences in the two forks. Draft notes:
- One seems more stable, the other one more feature rich for the sake of operations (e.g. backup, snapshot);
- To be checked whether Erlang API is the same;
- Identify kind of integration i.e. NF, dirty.
- Select one;
- Attempt inclusion in project. The two bindings have different build system (rebar vs. rebar3) so the other could be taken for easing integration.
I see there are two RocksDB bindings on hex:
They diverged a year ago - see 1 that is the same as 2.
In the following is a summary of the differences:
leo-project/erocksdb | barrel-db/erlang-rocksdb | |
---|---|---|
Build system | rebar | rebar3 |
RocksDB version | 4.13.5 | 5.7.2 |
Retrieval of C deps | Downloaded by script called by rebar hook | Committed in the git repository itself |
