type StorageConfig 

type StorageConfig struct {
	// Set to false to ensure ABCI responses are persisted. ABCI responses are
	// required for `/block_results` RPC queries, and to reindex events in the
	// command-line tool.
	DiscardABCIResponses bool `mapstructure:"discard_abci_responses"`
}

StorageConfig allows more fine-grained control over certain storage-related behavior.

func DefaultStorageConfig 

func DefaultStorageConfig() *StorageConfig

type TxIndexConfig 

type TxIndexConfig struct {
	// What indexer to use for transactions
	//
	// Options:
	//   1) "null"
	//   2) "kv" (default) - the simplest possible indexer,
	//      backed by key-value storage (defaults to levelDB; see DBBackend).
	//   3) "psql" - the indexer services backed by PostgreSQL.
	Indexer string `mapstructure:"indexer"`

}

----------------------------------------------------------------------------- TxIndexConfig Remember that Event has the following structure: type: [ 

key: value,
...

]

CompositeKeys are constructed by `type.key` TxIndexConfig defines the configuration for the transaction indexer, including composite keys to index.
