type DeleteAPI

type DeleteAPI interface {
	// Delete deletes series selected by the time range specified by start and stop arguments and optional predicate string from the bucket bucket belonging to the organization org.

DeleteAPI provides methods for deleting time series data from buckets. Deleted series are selected by the time range specified by start and stop arguments and optional predicate string which contains condition for selecting data for deletion, such as:

tag1="value1" and (tag2="value2" and tag3!="value3")

Empty predicate string means all data from the given time range will be deleted. See https://v2.docs.influxdata.com/v2.0/reference/syntax/delete-predicate/ for more info about predicate syntax.

package main

import (
	"context"

type PagingOption func(p *Paging)

PagingOption is the function type for applying paging option

func PagingWithAfter

func PagingWithAfter(after string) PagingOption

PagingWithAfter set after option - the last resource ID from which to seek from (but not including). This is to be used instead of `offset`.

func PagingWithDescending

func PagingWithDescending(descending bool) PagingOption

PagingWithDescending changes sorting direction

func PagingWithLimit

func PagingWithLimit(limit int) PagingOption

PagingWithLimit sets limit option - maximum number of items returned.

type QueryAPI

type QueryAPI interface {
	// QueryRaw executes flux query on the InfluxDB server and returns complete query result as a string with table annotations according to dialect
	QueryRaw(ctx context.Context, query string, dialect *domain.Dialect) (string, error)
	// QueryRawWithParams executes flux parametrized query on the InfluxDB server and returns complete query result as a string with table annotations according to dialect
	QueryRawWithParams(ctx context.Context, query string, dialect *domain.Dialect, params interface{}) (string, error)
	// Query executes flux query on the InfluxDB server and returns QueryTableResult which parses streamed response into structures representing flux table parts

	// QueryWithParams executes flux parametrized query  on the InfluxDB server and returns QueryTableResult which parses streamed response into structures representing flux table parts
	QueryWithParams(ctx context.Context, query string, params interface{}) (*QueryTableResult, error)
}

QueryAPI provides methods for performing synchronously flux query against InfluxDB server.

Flux query can contain reference to parameters, which must be passed via queryParams. it can be a struct or map. Param values can be only simple types or time.Time. The name of a struct field or a map key (must be a string) will be a param name. The name of the parameter represented by a struct field can be specified by JSON annotation:

type Condition struct {
    Start  time.Time  `json:"start"`
    Field  string     `json:"field"`
    Value  float64    `json:"value"`
	}

 Parameters are then accessed via the Flux params object:

 query:= `from(bucket: "environment")
		|> range(start: time(v: params.start))
		|> filter(fn: (r) => r._measurement == "air")
		|> filter(fn: (r) => r._field == params.field)
		|> filter(fn: (r) => r._value > params.value)`

NewQueryAPI returns new query client for querying buckets belonging to org

type QueryTableResult

type QueryTableResult struct {
	io.Closer
	// contains filtered or unexported fields
}

QueryTableResult parses streamed flux query response into structures representing flux table parts Walking though the result is done by repeatedly calling Next() until returns false. Actual flux table info (columns with names, data types, etc) is returned by TableMetadata() method. Data are acquired by Record() method. Preliminary end can be caused by an error, so when Next() return false, check Err() for an error

func NewQueryTableResult

func NewQueryTableResult(rawResponse io.ReadCloser) *QueryTableResult

NewQueryTableResult returns new QueryTableResult

func (*QueryTableResult) Close

func (q *QueryTableResult) Close() error

Close reads remaining data and closes underlying Closer

func (*QueryTableResult) Err

NewWriteAPI returns new non-blocking write client for writing data to bucket belonging to org

func (*WriteAPIImpl) Close

func (w *WriteAPIImpl) Close()

Close finishes outstanding write operations, stop background routines and closes all channels

func (*WriteAPIImpl) Errors

func (w *WriteAPIImpl) Errors() <-chan error

Errors returns a channel for reading errors which occurs during async writes. Must be called before performing any writes for errors to be collected. New error is skipped when channel is not read.

func (*WriteAPIImpl) Flush

func (w *WriteAPIImpl) Flush()

Flush forces all pending writes from the buffer to be sent. Flush also tries sending batches from retry queue without additional retrying.

func (*WriteAPIImpl) SetWriteFailedCallback

func (w *WriteAPIImpl) SetWriteFailedCallback(cb WriteFailedCallback)

SetWriteFailedCallback sets callback allowing custom handling of failed writes. If callback returns true, failed batch will be retried, otherwise discarded.

func (*WriteAPIImpl) WritePoint

func (w *WriteAPIImpl) WritePoint(point *write.Point)

WritePoint writes asynchronously Point into bucket. WritePoint adds Point into the buffer which is sent on the background when it reaches the batch size. Blocking alternative is available in the WriteAPIBlocking interface

func (*WriteAPIImpl) WriteRecord

func (w *WriteAPIImpl) WriteRecord(line string)

WriteRecord writes asynchronously line protocol record into bucket. WriteRecord adds record into the buffer which is sent on the background when it reaches the batch size. Blocking alternative is available in the WriteAPIBlocking interface

type WriteFailedCallback

type WriteFailedCallback func(batch string, error http2.Error, retryAttempts uint) bool

WriteFailedCallback is synchronously notified in case non-blocking write fails. batch contains complete payload, error holds detailed error information, retryAttempts means number of retries, 0 if it failed during first write. It must return true if WriteAPI should continue with retrying, false will discard the batch.
