// Here we compute a unique identifier for the row by computing the hash of
// its data. We exclude the current index, since the same row could have a
// different result index depending on the user permissions. We exclude also
// entity data, since serializing entity objects is very expensive. Instead
// we include entity cache tags, which are enough to identify all the
// entities associated with the row.

// into account: users having access to different sets of fields will get
// different row identifiers.

// Finally we compute a hash of row data and return it as row identifier.
