Database.InfluxDB.Query

Query interface

data Query

An InfluxDB query.

A spec of the format is available at https://docs.influxdata.com/influxdb/v1.7/query_language/spec/.

A Query can be constructed using either

• the IsString instance with -XOverloadedStrings
• or formatQuery.

>>> :set -XOverloadedStrings
>>> "SELECT * FROM series" :: Query
"SELECT * FROM series"
>>> import qualified Database.InfluxDB.Format as F
>>> formatQuery ("SELECT * FROM "%F.key) "series"
"SELECT * FROM \"series\""

NOTE: Currently this library doesn't support type-safe query construction.

Instances

Show Query

Defined in Database.InfluxDB.Types

Methods

showsPrec :: Int -> Query -> ShowS

show :: Query -> String

showList :: [Query] -> ShowS

IsString Query

Defined in Database.InfluxDB.Types

Methods

fromString :: String -> Query

query :: forall a. QueryResults a => QueryParams -> Query -> IO (Vector a)

Query data from InfluxDB.

It may throw InfluxException.

If you need a lower-level interface (e.g. to bypass the QueryResults constraint etc), see withQueryResponse.

queryChunked

Arguments

:: QueryResults a

=> QueryParams

-> Optional Int

Chunk size

By Default, InfluxDB chunks responses by series or by every 10,000 points, whichever occurs first. If it set to a Specific value, InfluxDB chunks responses by series or by that number of points.

-> Query

-> FoldM IO (Vector a) r

-> IO r

Same as query but it instructs InfluxDB to stream chunked responses rather than returning a huge JSON object. This can be lot more efficient than query if the result is huge.

It may throw InfluxException.

If you need a lower-level interface (e.g. to bypass the QueryResults constraint etc), see withQueryResponse.

Following lenses are available to access its fields:

• server
• database

• manager
• authentication
• decoder

Database name to work on.

precision :: HasPrecision ty a => Lens' a (Precision ty)

Time precision parameter.

manager :: HasManager a => Lens' a (Either ManagerSettings Manager)

decoder :: Lens' QueryParams Decoder

Parsing results

class QueryResults a where

Types that can be converted from an JSON object returned by InfluxDB.

For example the h2o_feet series in the official document can be encoded as follows:

>>> :{
data H2OFeet = H2OFeet
  { time :: UTCTime
  , levelDesc :: T.Text
  , location :: T.Text
  , waterLevel :: Double
  }
instance QueryResults H2OFeet where
  parseMeasurement prec _name _tags columns fields = do
    time <- getField "time" columns fields >>= parseUTCTime prec
    levelDesc <- getField "level_description" columns fields >>= parseJSON
    location <- getField "location" columns fields >>= parseJSON
    waterLevel <- getField "water_level" columns fields >>= parseJSON
    return H2OFeet {..}
:}

parseMeasurement

Methods

parseMeasurement

Arguments

:: Precision 'QueryRequest

Timestamp precision

-> Maybe Text

Optional series name

-> HashMap Text Text

Tag set

-> Vector Text

Field keys

-> Array

Field values

-> Parser a

Parse a single measurement in a JSON object.

coerceDecoder :: proxy a -> Maybe Decoder

Always use this Decoder when decoding this type.

Just dec means decoder in QueryParams will be ignored and be replaced with the dec. Nothing means decoder in QueryParams will be used.

Instances

QueryResults Void

QueryResults instance for empty results. Used by manage.

NOTE: This instance is deprecated because it's unclear from the name whether it can be used to ignore results. Use Empty when expecting an empty result. Use Ignored if you want to ignore any results.

Low-level functions

withQueryResponse

Arguments

:: QueryParams

-> Maybe (Optional Int)

Chunk size

By Nothing, InfluxDB returns all matching data points at once. By Just Default, InfluxDB chunks responses by series or by every 10,000 points, whichever occurs first. If it set to a Specific value, InfluxDB chunks responses by series or by that number of points.

-> Query

-> (Request -> Response BodyReader -> IO r)

-> IO r

Lower-level interface to query data.

Helper types

data Ignored

Ignored can be used in the result type of query when the result values are not needed.

>>> v <- query @Ignored (queryParams "dummy") "SHOW DATABASES"
>>> v
[]

Instances

Show Ignored

Defined in Database.InfluxDB.Query

Methods

showsPrec :: Int -> Ignored -> ShowS

show :: Ignored -> String

showList :: [Ignored] -> ShowS

QueryResults Ignored

Defined in Database.InfluxDB.Query

Methods

parseMeasurement :: Precision 'QueryRequest -> Maybe Text -> HashMap Text Text -> Vector Text -> Array -> Parser Ignored

coerceDecoder :: proxy Ignored -> Maybe Decoder

data Empty

Empty can be used in the result type of query when the expected results are always empty. Note that if the results are not empty, the decoding process will fail:

>>> let p = queryParams "empty"
>>> Database.InfluxDB.Manage.manage p "CREATE DATABASE empty"
>>> v <- query @Empty p "SELECT * FROM empty" -- query an empty series
>>> v
[]

Instances

Show Empty

Defined in Database.InfluxDB.Query

show :: Empty -> String

showList :: [Empty] -> ShowS

QueryResults Empty

Methods

coerceDecoder :: proxy Empty -> Maybe Decoder

newtype Tagged (s :: k) b

A Tagged s b value is a value b with an attached phantom type s. This can be used in place of the more traditional but less safe idiom of passing in an undefined value with the type, because unlike an (s -> b), a Tagged s b can't try to use the argument s as a real value.

Moreover, you don't have to rely on the compiler to inline away the extra argument, because the newtype is "free"

Tagged has kind k -> * -> * if the compiler supports PolyKinds, therefore there is an extra k showing in the instance haddocks that may cause confusion.
