Functions ¶
func GetFieldNames ¶
func GetFieldNames(qctx *logstorage.QueryContext) ([]logstorage.ValueWithHits, error)
GetFieldNames executes qctx and returns field names seen in results.
func GetFieldValues ¶
func GetFieldValues(qctx *logstorage.QueryContext, fieldName string, limit uint64) ([]logstorage.ValueWithHits, error)
GetFieldValues executes the given qctx and returns unique values for the fieldName seen in results.
If limit > 0, then up to limit unique values are returned.
func GetStreamFieldNames ¶
func GetStreamFieldNames(qctx *logstorage.QueryContext) ([]logstorage.ValueWithHits, error)
GetStreamFieldNames executes the given qctx and returns stream field names seen in results.
func GetStreamFieldValues ¶
func GetStreamFieldValues(qctx *logstorage.QueryContext, fieldName string, limit uint64) ([]logstorage.ValueWithHits, error)
GetStreamFieldValues executes the given qctx and returns stream field values for the given fieldName seen in results.
If limit > 0, then up to limit unique stream field values are returned.
func GetStreamIDs ¶
func GetStreamIDs(qctx *logstorage.QueryContext, limit uint64) ([]logstorage.ValueWithHits, error)
GetStreamIDs executes the given qctx and returns streamIDs seen in query results.
If limit > 0, then up to limit unique streamIDs are returned.
func GetStreams ¶
func GetStreams(qctx *logstorage.QueryContext, limit uint64) ([]logstorage.ValueWithHits, error)
GetStreams executes the given qctx and returns streams seen in query results.
If limit > 0, then up to limit unique streams are returned.
func Init ¶
func Init()
Init initializes vtstorage.
Stop must be called when vtstorage is no longer needed
func RequestHandler ¶
func RequestHandler(w http.ResponseWriter, r *http.Request) bool
RequestHandler is a storage request handler.
func RunQuery ¶
func RunQuery(qctx *logstorage.QueryContext, writeBlock logstorage.WriteDataBlockFunc) error
RunQuery runs the given qctx and calls writeBlock for the returned data blocks
func UpdatePerQueryStatsMetrics ¶ added in v0.3.0
func UpdatePerQueryStatsMetrics(qs *logstorage.QueryStats)
UpdatePerQueryStatsMetrics updates query stats metrics with the given qs.
Types ¶
type Storage ¶
type Storage struct{}
Storage implements insertutil.LogRowsStorage interface
func (*Storage) CanWriteData ¶
CanWriteData returns non-nil error if it cannot write data to vtstorage
func (*Storage) MustAddRows ¶
func (*Storage) MustAddRows(lr *logstorage.LogRows)
MustAddRows adds lr to vtstorage
It is advised to call CanWriteData() before calling MustAddRows()
