values := map[string]map[string][]byte{"cf": map[string][]byte{"a": []byte{0}}}
putRequest, err := hrpc.NewPutStr(context.Background(), "table", "key", values)
rsp, err := client.Put(putRequest)
Get an entire row
getRequest, err := hrpc.NewGetStr(context.Background(), "table", "row")
getRsp, err := client.Get(getRequest)
Get a specific cell
// Perform a get for the cell with key "15", column family "cf" and qualifier "a"
family := map[string][]string{"cf": []string{"a"}}
getRequest, err := hrpc.NewGetStr(context.Background(), "table", "15",
hrpc.Families(family))
getRsp, err := client.Get(getRequest)
Get a specific cell with a filter
pFilter := filter.NewKeyOnlyFilter(true)
family := map[string][]string{"cf": []string{"a"}}
getRequest, err := hrpc.NewGetStr(context.Background(), "table", "15",
hrpc.Families(family), hrpc.Filters(pFilter))
getRsp, err := client.Get(getRequest)
Scan with a filter
pFilter := filter.NewPrefixFilter([]byte("7"))
scanRequest, err := hrpc.NewScanStr(context.Background(), "table",
