--- Comment #1 from Stefan Brüns <stefan.bru...@rwth-aachen.de> --- Unfortunately even the two most fundamental databases in baloo, the Terms and the FileNameTerms DBs, show O(M^2) behaviour on updates. Everytime e.g. a "pdf" is changed, the associated value (i.e. the IDs of all matching documents) for the "pdf" term is updated. An update may happen in two cases: 1. an existing file is appended, tagged, renamed ... 2. an existing file is replaced by an updated one (i.e. application creates a temporary file on saving and atomically replaces the old one). For (1.), the update can be minimized, i.e. only updating the terms which have actually changed. I have some experimental patches for this. For (2.), the database scheme has to be changed significantly. -- You are receiving this mail because: You are watching all bug changes.
