When using the index you must provide it with an IndexMapping. The IndexMapping provides the index with the contract it needs to populate the entire index and traverse a populated index correctly. The IndexMapping provides a way to retrieve the key on which to index with when provided with the value from the source. It also provides the way to access the source bucket.

The following is an illustration of its use:

byUserID := func(v []byte) ([]byte, error) {
    auth := &influxdb.Authorization{}

    if err := json.Unmarshal(v, auth); err != nil {
        return err
    }

    return auth.UserID.Encode()
}

// configure a write only index
indexByUser := NewIndex(NewSource([]byte(`authorizationsbyuserv1/), byUserID))

indexByUser.Insert(tx, someUserID, someAuthID)

indexByUser.Delete(tx, someUserID, someAuthID)

indexByUser.Walk(tx, someUserID, func(k, v []byte) error {
    auth := &influxdb.Authorization{}
    if err := json.Unmarshal(v, auth); err != nil {
        return err
    }

    // do something with auth

    return nil
})

// populate entire index from source
indexedCount, err := indexByUser.Populate(ctx, store)

// verify the current index against the source and return the differences
// found in each
diff, err := indexByUser.Verify(ctx, tx)

func NewIndex

func NewIndex(mapping IndexMapping, opts ...IndexOption) *Index
