Re: Solr background merge in case of pull replicas

Hi Kshitij What I can guess over here. Pull replicas replicate segments from tlog, so whenever merge happens on tlog it will decrease the number of segments which is more than ideal case(i.e. adding a new segment). Afaik adding/deleting the segment is kind of a stop the world moment. This can be

Query over migrating a solr database from 7.7.1 to 8.7.0

Hi There I have recently upgraded a solr database from 7.7.1 to 8.7.0 and not wiped the database and re-indexed (as this would take too long to run on site). On my local windows machine I have a single solr server 7.7.1 installation I upgraded in the following manner *

RE: Sending compressed (gzip) UpdateRequest with SolrJ

Answering to myself on this one. Solr uses Jetty 9.x which does not support compressed requests by itself meaning, the application behind Jetty (that is Solr) has to decompress by itself which is not the case for now. Thus even without using SolrJ, sending XML compressed in GZIP to Solr (with

Interpreting Solr indexing times

Hello all, I have been looking at our SolrCloud indexing performance statistics and trying to make sense of the numbers. We are using a custom Flume sink and sending updates to Solr (8.4) using SolrJ. I know these stuff depend on a lot of things but can you tell me if these statistics are

Re: Converting a collection name to an alias

I believe you may be able to use that command (or some combination of create alias commands) to create an alias from A to A, and then in the future when you want to change it you can have Alias A to collection B (assuming this is the point of the alias in the first place). On Thu, Jan 7, 2021 at

The x: prefix for the core name and 'custom.vm' errors in Admin UI's Logging tab

Please disregard my previous post. I understand these are actual error messages, not the errors of handling Admin UI. I think this server is being attacked using the vulnerability described here

Converting a collection name to an alias

Hi again, Lets say I have a collection named A. I’m trying to rename it to A_1, then create an alias named A, which points to the A_1 collection. Is this possible without deleting and reindexing the collection from scratch? Regards, uyilmaz

Re: Sending compressed (gzip) UpdateRequest with SolrJ

jetty supports http gzip and I've added it to solr before in my own installs (and submitted patches to do so by default to solr) but I don't know about the handling for solrj. IME compression helps a little, sometimes a lot, and never hurts. Even the admin interface benefits a lot from regular

Solr query with space (only) gives error

StandardTokenizerFactory doesn't split on underscore
