Constants

const BatchSize = 100

BatchSize is the safe number of records to cache during Batch calls for SQLite without causing load problems. NOTE: Now we no longer support SQLite, perhaps this can be tuned?

Variables

	// ErrorNotFound is returned when finding a single value fails.

func (Config) EthBalanceMonitorBlockDelay added in v0.8.12 

func (c Config) EthBalanceMonitorBlockDelay() uint16

func (Config) EthFinalityDepth added in v0.8.7 

func (c Config) EthFinalityDepth() uint

EthFinalityDepth is the number of blocks after which an ethereum transaction is considered "final" BlocksConsideredFinal determines how deeply we look back to ensure that transactions are confirmed onto the longest chain There is not a large performance penalty to setting this relatively high (on the order of hundreds) It is practically limited by the number of heads we store in the database and should be less than this with a comfortable margin. If a transaction is mined in a block more than this many blocks ago, and is reorged out, we will NOT retransmit this transaction and undefined behaviour can occur including gaps in the nonce sequence that require manual intervention to fix. Therefore this number represents a number of blocks we consider large enough that no re-org this deep will ever feasibly happen.

	// When the connection is opened, it starts a transaction and all
	// operations performed on the DB will be within that transaction.
	//
	// HACK: This must be the string 'cloudsqlpostgres' because of an absolutely
	// horrible design in gorm. We need gorm to enable postgres-specific
	// features for the txdb driver, but it can only do that if the dialect is
	// called "postgres" or "cloudsqlpostgres".
	//
	// Since "postgres" is already taken, "cloudsqlpostgres" is our only
	// remaining option
	//
	// See: https://github.com/jinzhu/gorm/blob/master/dialect_postgres.go#L15
	DialectTransactionWrappedPostgres DialectName = "cloudsqlpostgres"
