Functionsยง

decode_primary_key ๐Ÿ”’
is_reserved_column ๐Ÿ”’
rows_to_batch ๐Ÿ”’
series_index_schema
Returns the Arrow schema of a series index.
tag_columns ๐Ÿ”’
timestamp_values ๐Ÿ”’
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 โ€” the index schema or the searcher must record the unit per file, or the index must be rebuilt on such an alter.
