...ngs We are looking into a solution to set up full text search for our multiple Dovecot instances. According to the Dovecot Wiki, fts_solr is one of the recommended plugins to use. Since we have more than just a few hundred mailboxes, I guess one Solr instance will not suffice. So I took a look at SolrCloud and set up a small cluster with three nodes and shards. I have no preceding experience with Solr or SolrCloud and now it's not clear to me, how dovecot can interact with this cluster. Has anyone ever tried to setup dovecot FTS with a SolrCloud cluster and is willing to share his findings? Reg...

Hi, guys, Can you give me an example of solr usage in dovecot? As far as I know, you can search email easily by MUA like outlook, so which role does solr play? And based on https://dovecot.org/pipermail/dovecot/2019-April/115575.html I'm going to use an VIP to host 2 mail servers. Currently, it works in fail over and fail back test except solr index, so how to resolve this? Is it

Probably the easiest is SolrCloud, because the legacy master-slave replication option basically has the master as a single point of failure. Switching a slave to master is a very manual job. SolrCloud is a true cluster -- no masters and no slaves. Normally I would suggest a load balancer in front of Solr, but with SolrCloud...

Hi all, Has anyone implemented larger Dovecot+Solr clusters and would be willing to give some details about how it works for you? My understanding about it so far is: - SolrCloud isn?t usable with Dovecot. Replication isn?t useful, because nobody wants to pay for double the disk space for indexes that could be regenerated anyway. The autosharding isn?t very useful also, because: I think the shard keys could be created in two possible ways: a) Mails would be entirely randoml...

Hi I have set up SOLR in accordance with documentation and it runs well. I use solr like: ....... fts = solr fts_solr = debug url=http://IP:8983/solr/ (solr in external machine) ...... Is replication of this system really essential ?? Due to my tests, rollback of the solr server on external machine lasts less than minute and it is nearly non-visible from client side. On the other hand solr
