UtxoState on MvStore #2

Closed pragmaxim closed 1 year ago

pragmaxim commented 1 year ago

Agenda :

switch UtxoState to H2.MvStore
configurable Modes :
- MvStore (single JVM process only - lightweight p2p explorer mode suitable for dApps devs)
- MvStore + Cassandra
- MvStore + Cassandra + JanusGraph
- MvStore + JanusGraph on Cassandra

MvStore :

supports rollback to previous revisions which is perfect for handling blockchain forks
has much better querying possibilities than LevelDB or RocksDB
is a bit slower and more complicated than LevelDB/RocksDB

From data perspective :

MvStore can hold UtxoState + limited data by requirements
Cassandra contains all data accessible in real-time
JanusGraph - data indexed as a graph for analysis
