Table.readWhere() can be O(1) if you use indexing (see Column.createIndex() method). In addition, if your table is sorted, the indexing method is specially efficient for doing the retrieval, as can be seen in: http://www.pytables.org/docs/manual/ch05.html#Sorting-indexes -- Francesc Alted ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
