Description
This is an experimental feature release based on v1.6.1-beta, with binary version: v1.6.100.
v1.6.1-beta-feature-ScalableDB introduces a multi-database architecture (scalaledb) that divides chaindata into four separate stores which incluing BlockDataBase(with meta), TrieDataBase, SnapDataBase and IndexDataBase according to data schema . Scalaledb provides stronger storage scalability. Different DBs can be allocated customized resources and tuned configurations. In particular, databases can compact independently, avoiding interference and improving read performance under heavy I/O.
Run
Run geth from genesis with "multidatabse" flag:
./geth --config config.toml --datadir data-seed init --multidatabase genesis.json
If you run geth from snapshot, you need to use migrate tool to convert an existing snapshot to the scalaledb layout with
./geth -datadir <your-data-dir> db migrate . You can directly start after migration , no additional flags are required if your snapshot has already been migrated.
Performance Test Results:
In large-scale simulated benchmarks, Multi-DB improves Geth block sync performance by ~3.8%. Starting from the same block height, after seven days of syncing, the Multi-DB node was ahead by ~200,000 blocks.
