fn timestamp_values(array: &ArrayRef) -> Result<Int64Array>Expand description
Extracts raw i64 timestamp values for the __series_min_ts/__series_max_ts
columns. NOTE: the unit is dropped; the values must always be interpreted in
the unit of the region metadata the index is written with. Once this index
is wired into scans, files written before/after a time index unit widening
would carry mixed units — the index schema or the searcher must record the
unit per file, or the index must be rebuilt on such an alter.
