I'd like to use the DataImportHandler running against a slave database that, at any given time, may be significantly behind the master DB. This can cause updates to be missed if you use the clock-time as the "last_index_time." E.g., if the slave catches up to the master between two delta-imports.
Has anyone run into this? In our non-DIH indexing system we get around this by either using the slave DB's seconds-behind-master or the max last update time of the records returned. Thanks. Gregg
