=quote from http://www.sphinxsearch.com/docs/current.html 3.12. Index merging
Merging two existing indexes can be more efficient that indexing the data from scratch, and desired in some cases (such as merging 'main' and 'delta' indexes instead of simply reindexing 'main' in 'main +delta' partitioning scheme). So indexer has an option to do that. Merging the indexes is normally faster than reindexing but still not instant on huge indexes. Basically, it will need to read the contents of both indexes once and write the result once. Merging 100 GB and 1 GB index, for example, will result in 202 GB of IO (but that's still likely less than the indexing from scratch requires). The basic command syntax is as follows: indexer --merge DSTINDEX SRCINDEX [--rotate] = I think if I can merge delta data into main data, then we don't have to reindex everyday, that would be great. but I saw the post[1], Pat said something like that[2].) it seems delta doesn't merge into man index? we need reindex everyday or every few hours? -------- 1:(http://groups.google.com/group/thinking-sphinx/browse_thread/thread/ cdf0c676177d336a/83d756b221ba3a16?lnk=raot) 2:(If you were running the rake task every two hours, then changes made in that first hour after you run it will not be caught, until you do a full reindex (which should still happen regularly - once a day, perhaps?) -- You received this message because you are subscribed to the Google Groups "Thinking Sphinx" group.
