Types

type CassandraDevops 

type CassandraDevops struct {
	bulkQuerygen.CommonParams
	KeyspaceName string
}

CassandraDevops produces Cassandra-specific queries for all the devops query types.

func (*CassandraDevops) Dispatch

func (*CassandraDevops) MeanCPUUsageDayByHourAllHostsGroupbyHost 

func (d *CassandraDevops) MeanCPUUsageDayByHourAllHostsGroupbyHost(qi bulkQuerygen.Query)

MeanCPUUsageDayByHourAllHosts populates a Query with a query that looks like: SELECT mean(usage_user) from cpu where time >= '$DAY_START' and time < '$DAY_END' group by time(1h),hostname

type CassandraDevops8Hosts 

type CassandraDevops8Hosts struct {
	CassandraDevops
}

CassandraDevops8Hosts produces Cassandra-specific queries for the devops groupby case.

func (*CassandraDevops8Hosts) Dispatch 

func (d *CassandraDevops8Hosts) Dispatch(i int) bulkQuerygen.Query

type CassandraDevopsGroupby 

type CassandraDevopsGroupby struct {
	CassandraDevops
}

CassandraDevopsGroupby produces Cassandra-specific queries for the devops groupby case.

func (*CassandraDevopsGroupby) Dispatch 

func (d *CassandraDevopsGroupby) Dispatch(i int) bulkQuerygen.Query

type CassandraDevopsSingleHost 

type CassandraDevopsSingleHost struct {
	CassandraDevops
}

CassandraDevopsSingleHost produces Cassandra-specific queries for the devops single-host case.

func (*CassandraDevopsSingleHost) Dispatch 

func (d *CassandraDevopsSingleHost) Dispatch(i int) bulkQuerygen.Query

type CassandraDevopsSingleHost12hr

type CassandraIot 

type CassandraIot struct {
	bulkQuerygen.CommonParams
	KeyspaceName string
}

CassandraIot produces Cassandra-specific queries for all the devops query types.

func (*CassandraIot) AverageTemperatureDayByHourOneHome 

func (d *CassandraIot) AverageTemperatureDayByHourOneHome(q bulkQuerygen.Query)

func (*CassandraIot) Dispatch 

func (d *CassandraIot) Dispatch(i int) bulkQuerygen.Query

Dispatch fulfills the QueryGenerator interface.

type CassandraIotSingleHost 

type CassandraIotSingleHost struct {
	CassandraIot
}

CassandraIotSingleHost produces Cassandra-specific queries for the devops single-host case.

func (*CassandraIotSingleHost) Dispatch

type CassandraQuery 

type CassandraQuery struct {
	HumanLabel       []byte
	HumanDescription []byte

	MeasurementName []byte // e.g. "cpu"
	FieldName       []byte // e.g. "usage_user"
	AggregationType []byte // e.g. "avg" or "sum". used literally in the cassandra query.
	TimeStart       time.Time
	TimeEnd         time.Time
	GroupByDuration time.Duration
	TagsCondition   []byte
}

CassandraQuery encodes a Cassandra request. This will be serialized for use by the query_benchmarker program.
