Types ¶
type Descriptor ¶
type Descriptor struct {
// Current is the current descriptor
Current *pb.DescriptorProto

type Iter ¶
type Iter interface {

Next() (bool, error)
// Key returns the key of the current row.
Key() string
// Timestamp returns the timestamp of the current row.
Timestamp() int64
// Value returns the value of the current row.
Value() []byte
// Close closes the iterator.
Close()
}
Iter is an iterator over rows.
func NewIterFromRows ¶
NewIterFromRows returns an Iter represents rows. rows must not be modified after.
type Options ¶
type Options struct {
SstDir string
MemtableFlushSize int64
LogDir string
TargetLogSize int64
// BlockCacheSize is the size of the block cache. 0 disables the cache.
BlockCacheSize int64
DescriptorDir string
}
func DefaultOptions ¶
