Types

type ColumnType

type ColumnType int

const (
	BOOLEAN               ColumnType = 0
	INT8                  ColumnType = 1
	INT16                 ColumnType = 2
	INT32                 ColumnType = 3
	INT64                 ColumnType = 4
	UINT8                 ColumnType = 5
	UINT16                ColumnType = 6
	UINT32                ColumnType = 7
	UINT64                ColumnType = 8
	FLOAT32               ColumnType = 9
	FLOAT64               ColumnType = 10
	BINARY                ColumnType = 11
	STRING                ColumnType = 12
	DATE                  ColumnType = 13
	DATETIME              ColumnType = 14
	TIMESTAMP_SECOND      ColumnType = 15
	TIMESTAMP_MILLISECOND ColumnType = 16
	TIMESTAMP_MICROSECOND ColumnType = 17
	TIMESTAMP_NANOSECOND  ColumnType = 18

	JSON ColumnType = 31

	// the following types are not from protocol buffer
	INT       ColumnType = 101
	UINT      ColumnType = 102
	FLOAT     ColumnType = 103
	TIMESTAMP ColumnType = 104
	BYTES     ColumnType = 105 // eq BINARY
	BOOL      ColumnType = 106 // eq BOOLEAN
)

DO NOT CHANGE THE ORDER OF THESE CONSTANTS THEY WILL KEEP EXACTLY THE SAME ORDER WITH PROTOCOL BUFFER https://github.com/GreptimeTeam/greptime-proto/blob/main/proto/greptime/v1/common.proto#L78-L110

ColumnType has richer types than ColumnDataType in protocol buffer

func (ColumnType) String

func (type_ ColumnType) String() string

type Operation

type Operation uint

Operation is to identify the operation type of the request. current supported:

• Insert
• Delete

TODO: [Update]

const (
	INSERT Operation = iota
	DELETE
)

type TimestampPrecision

type TimestampPrecision string

const (
	SECOND      TimestampPrecision = "second"
	MILLISECOND TimestampPrecision = "millisecond"
	MICROSECOND TimestampPrecision = "microsecond"
	NANOSECOND  TimestampPrecision = "nanosecond"
)

func (TimestampPrecision) String

func (p TimestampPrecision) String() string
