Re: Force open a searcher in solr.
So to make things clear, belows what I am expecting I have a document with a unique id field lets say "uniqueID". This document has both stored/indexed and not stored/ not indexed fields Currently I have my pop values in external files but I will instead define a new field in schema (popVal) which will not be stored or indexed and have docValues=true. I am also moving _version_ field to indexed=false and stored=false, since I don't have any case where I retrieve it and use it for searching. Just hoping doing this doesn't cause any issues with updates in general (I read that keeping this as not stored and not indexed is recommended since solr 7) Regards, Akshay On Thu, Aug 13, 2020 at 4:53 PM Erick Erickson wrote: > Let us know how it works.

Re: Reaching max Filter cache limit increases the request latencies.
Hey Erick,
So I am investigating the point where we can limit the values that are
cached using {!cache=false} (we already use it in some of our cases)
So in general there is 0 evictions on filter cache side but whenever we hit
this max limit there is a spike in evictions as well (which is expected)
As far as I remember not forcing enum on our side, but will definitely
verify that.
My filter cache hit ratio remains constant at around 97.5 % and even
during this eviction the hit ratio doesn't go down
Regarding other operation there are a few cases where indexing (80 to 150
docs) also happened during that time but there are also cases where index
happened 5- 10 min after that and the latencies remained high.
Regards,
Akshay

Re: Force open a searcher in solr.
Hey Erick, Thanks for the information about the doc ID field. So our external file values are single float value fields and we do use them in functional queries in boost parameter, so based on the definition the above should work. So currently we use solr 5.4.0 but are in the process of upgrading our systems so will try out this change.

Re: Force open a searcher in solr.
Hey,
So I have external file fields that have some data that get updated
regularly. Whenever those get updated we need the open searcher operation
to happen. The value in this external files are used in boosting and other
function/range queries.

Force open a searcher in solr.
Hey,
I have a use case where none of the document in my solr index is changing but I
still want to open a new searcher through the curl api.

curl “XXX.XX.XX.XXX:9744/solr/mycollection/update?openSearcher=true=true”
it doesn’t open a new searcher. Below is what I get in logs

I don’t want to do a complete reload of my collection.
Is there any parameter that can be used to forcefully open a new searcher every

Solr reload process flow
Hey, I am using solr-5.4.0 in my production environment and am trying to automate the reload/restart process of the solr collections based on certain specific conditions. I noticed that on solr reload the thread count increases a lot there by resulting in increased latencies. So I read about reload process and came to know that while reloading 1) Solr creates a new core internally and then assigns this core same name as the old core. Is this correct? 2) If above is true then does solr actually create a new index internally on reload? 3) If so then restart sounds much better than reload, or is there any better way to upload new configs on solr? 4) Can you point me to any docs that can give me more details about this? Any help would be appreciated, Thank you. Regards, Akshay
Re: Example Solr Config on EC2
Yes you can promote a slave to be master refer http://wiki.apache.org/solr/SolrReplication#enable.2BAC8-disable_master.2BAC8-slave_in_a_node In AWS one can use an elastic IP(http://aws.amazon.com/articles/1346) to refer to the master and this can be assigned to slaves as they assume the role of master(in case of failure). All slaves will then refer to this new master and there will be no need to regenerate data. Automation of this maybe possible through CloudWatch alarm-actions. I don't know of any available example automation scripts. Cheers Akshay.

Auto-scaling solr setup
So i am trying to setup an auto-scaling search system of ec2 solr-slaves which scale up as number of requests increase and vice versa Here is what I have 1. A solr master and underlying slaves(scalable). And an elastic load balancer to distribute the load. 2. The ec2-auto-scaling setup fires nodes when traffic increases. However the replication times(replication speed) for the index from the master varies for these newly fired nodes. 3. I want to avoid addition of these nodes to the load balancer till it has completed initial replication and has a warmed up cache. For this I need to know a way I can check if the initial replication has completed. and also a way of warming up the cache post this. I can think of doing this via .. a shellscript/awk(checking times replicated/index size) ... is there a cleaner way ? Also on the side note .. any suggestions or pointers to how one set up their scalable solr setup on cloud(AWS mainly) would be helpful. Regards, Akshay
Re: Auto-scaling solr setup
Yes sadly .. I too have not much clue about AWS. The SolrReplication API doesnt give me what i want exactly.. For the time being i have hacked my way into the amazon image bootstrapping the replication check in a shell script ((curl awk) very dirty way) . Once the check suceeds I enable the server using the Solr healthcheck for load-balancers. I was wondering if anyone has moved to the cloud..specially Amazon auto-scaling where they dont have control over when a new node is fired.. All scenarios i encountered were people creating a node .. warming up the cache and then adding it under the HAProxy LB. I guess warmup is not that big an issue as compared to an empty response. Thanks for your response :) Regards, Akshay On Mon, Jun 6, 2011 at 6:33 PM, Erick Erickson erickerick...@gmail.comwrote: The HTTP interface (http://wiki.apache.org/solr/SolrReplication#HTTP_API) can be used to control lots of parts of replication. As to warmups, I don't know of a good way to test that. I don't know whether getting the current status on the slave includes whether warmup is completed or not. At worst, after replication is complete you could wait an interval (see the warmup times on your running servers) before routing requests to the slave. I haven't any clue at all about AWS...

However the replication times(replication speed) for the index from the master varies for these newly fired nodes. 3. I want to avoid addition of these nodes to the load balancer till it has completed initial replication and has a warmed up cache. For this I need to know a way I can check if the initial replication has completed. and also a way of warming up the cache post this. I can think of doing this via .. a shellscript/awk(checking times replicated/index size) ... is there a cleaner way ? Also on the side note .. any suggestions or pointers to how one set up their scalable solr setup on cloud(AWS mainly) would be helpful. Regards, Akshay
Re: replicated index files have incorrect timestamp
You need to specify the index version number for which list of files is to be shown.

Step 3 is the problem. I don't have a reliable way to know it has finished replication AFAIK. I see in ?action=STATUS for the CoreAdmin there is a field called current. Is this useful for this? If not, what is recommended. I could hit the admin/replication/index.jsp url and screenscrape the HTML, but I imagine there is a better way. From the slave you can issue a http command, boot-$CoreName/replication?command=details this returns XML which contains a node isReplicating having boolean value.
