I cycled through the compaction on another node. Again after 3 rounds compaction has stopped. On one node the merge index is 26 GB on the other 21 GB. So it looks like I've hit the 5 segment compaction no-op condition on both nodes.
What would account for the difference in merge_index size? Shouldn't these be relatively the same? There must still be tombstones in there... On my production cluster the merge_index is ~44GB. I estimate that approximately 90 - 95% of the index data belongs to the bucket I no longer want indexed. Manually deleting items from the index then manually triggering compaction doesn't look like it will scale. Will this workflow work to re-build the search index. I need to keep the cluster available for writes while doing this: 1. In a rolling fashion, disable Riak Search one node at a time. 2. Delete the contents of the merge_index on each node. 3. In a rolling fashion, re-enable Riak Search on each node. 4. Reindex the items to be included in the search index. This should do the trick right? Do I need to disable search before clearing out the merge_index folders or would disabling the search index on the buckets via search-cmd be enough (and then re-enabling) before re-indexing? -- Jeremy On Fri, Nov 2, 2012 at 11:19 AM, Ryan Zezeski <rzeze...@basho.com> wrote: > "Active" is any segment file that has the suffix .data. > > [Sent from my iPhone] > > On Nov 2, 2012, at 11:11 AM, Jeremy Raymond <jeraym...@gmail.com> wrote: > > When do segments become active/inactive? > > -- > Jeremy > > > On Fri, Nov 2, 2012 at 10:50 AM, Ryan Zezeski <rzeze...@basho.com> wrote: > >> >> >> On Fri, Nov 2, 2012 at 9:52 AM, Jeremy Raymond <jeraym...@gmail.com>wrote: >> >>> Some files changed and some didn't. >>> Not really sure how to interpret the differences. >>> >>> >> Another thing, compacting will occur only if there are 6 or more active >> segments.
