Functions

func BackupHandler

func BackupHandler(db Database) func(http.ResponseWriter, *http.Request)

BackupHandler for accepting requests to initiate a new database backup.

Types

type Database

type Database = iface.Database

Database defines the necessary methods for Prysm's eth2 backend which may be implemented by any key-value or relational database in practice. This is the full database interface which should not be used often. Prefer a more restrictive interface in this package.

func NewDB

func NewDB(dirPath string, stateSummaryCache *cache.StateSummaryCache) (Database, error)

NewDB initializes a new DB with kafka wrapper.

type HeadAccessDatabase

type HeadAccessDatabase = iface.HeadAccessDatabase

HeadAccessDatabase exposes Prysm's eth2 backend for read/write access with information about chain head information. This interface should be used sparingly as the HeadFetcher is the source of truth around chain head information while this interface serves as persistent storage for the head fetcher.

See github.com/prysmaticlabs/prysm/blockchain.HeadFetcher

type NoHeadAccessDatabase

type NoHeadAccessDatabase = iface.NoHeadAccessDatabase

NoHeadAccessDatabase exposes Prysm's eth2 data backend for read/write access, no information about head info. For head info, use github.com/prysmaticlabs/prysm/blockchain.HeadFetcher.

type ReadOnlyDatabase

type ReadOnlyDatabase = iface.ReadOnlyDatabase

ReadOnlyDatabase exposes Prysm's eth2 data backend for read access only, no information about head info. For head info, use github.com/prysmaticlabs/prysm/blockchain.HeadFetcher.
