   Event Store allows users to query events emitted from contracts running on our chain.

   The following is the config to enable Event Store

   EventStore:
     DBName: {{.EventStore.DBName}} // Set DB name (can be anything, default is events)
     DBBackend: {{.EventStore.DBBackend}} // Set DB type 'goleveldb' or 'cleveldb'
   {{end}}
   
   EventDispatcher:
     Dispatcher: {{.EventDispatcher.Dispatcher}} // Available dispatcher: "db_indexer" | "log" | "redis"
     # Redis will be use when Dispatcher is "redis"
     Redis:
       URI: "{{.EventDispatcher.Redis.URI}}"// Redis URI
   

   Config example

   EventDispatcher:
     Dispatcher: db_indexer
   
   EventStore:
     DBName: "event"
     DBBackend: "goleveldb"
   

   Now you can query emitted event fromBlock to toBlock
