Abstract
Embodiments of the present disclosure provide techniques for deduplicating files to be ingested by a database. A bloom filter may be built for each of a first set of files that are ingested into the database. The set of bloom filters may be stored in a metadata storage associated with the database along with file loading metadata of the first set of files. In response to receiving a set of candidate files to be ingested into the database, one or more candidate files that are duplicative of a file in the first set of files are removed from the set of candidate files, based on file loading metadata of each the first set of files and the set of candidate files to generate a reduced set of candidate files. From the reduced set of candidate files, candidate files that are not duplicative are identified and set for ingestion while candidate files that are potentially duplicative are also identified and set for further scanning.
