var DefaultOptions = &Options{
CacheCapacity: 512 * 1024 * 1024,
WriteBufferSize: 60 * 1024 * 1024,
}
DefaultOptions is the default Options struct passed to Open when not otherwise given one.
Functions ¶
func CompactRange ¶ added in v0.0.30
CompactRange runs a manual compaction on the Range of keys given. If r == nil, the entire table will be compacted.
func Open ¶
Open returns a keyvalue DB backed by a LevelDB database at the given filepath. If opts==nil, the DefaultOptions are used.
func OpenGraphStore ¶
func OpenGraphStore(path string, opts *Options) (graphstore.Service, error)
OpenGraphStore returns a graphstore.Service backed by a LevelDB database at the given filepath. If opts==nil, the DefaultOptions are used.
Types ¶
type Options ¶
type Options struct {
// CacheCapacity is the caching capacity (in bytes) used for the LevelDB.
CacheCapacity int
// CacheLargeReads determines whether to use the cache for large reads. This
// is usually discouraged but may be useful when the entire LevelDB is known
// to fit into the cache.
CacheLargeReads bool
// WriteBufferSize is the number of bytes the database will build up in memory
// (backed by a disk log) before writing to the on-disk table.
WriteBufferSize int
// MustExist ensures that the given database exists before opening it. If
// false and the database does not exist, it will be created.
MustExist bool
}
Options for customizing a LevelDB backend.
