So we're running Solr in a Master/Slave configuration (1 of each) and it seems
that the replication stalls or stops functioning every now and again. If we
restart the Solr service or optimize the core it seems to kick back in again.
Anyone have any idea what might be causing this? We do have a
This happens to me quite often as well. Generally on the replication admin
screen it will say its downloading a file, but be at 0 or a VERY small
kb/sec. Then after a restart of the slave its back to downloading at 30 to
100 mg/sec. Would be curious if there actually is a solution to this aside
I'm at the point now where I may end up writing a script to compare
master/slave nightly...and trigger an optimize or solr restart if there are any
differences. Of course I have to check 150+ cores...but it could be done. I'm
just hoping I don't need to go that route

I do have a ticket in with our systems team to up the file handlers since I am
seeing the "Too many files open" error on occasion on our prod servers. Is
this the setting you're referring to? Found we were set to to 1024 using the
"Ulimit" command.

We usually recommend setting files and processes very, very high. Like
65K high. Or unlimited if you can.
Plus max user processes should also be bumped very high as well, like
65K as well.
Plus max memory and virtual memory should be unlimited.
We've included warnings at startup for open
Erick,
Thanks! Could these settings be toying with replication? Solr itself seems to
be working like a champ, except when things get out of sync.

"Could be", certainly. "Definitely is" is iffier ;)...
But the statement "If we restart the Solr service or optimize the core
it seems to kick back in again.", especially the "optimize" bit
(which, by the way you should do only if you have the capability of
doing it periodically [1]) is some evide
That's evidence enough for me to beat on our systems guys to get these file
handles upped and cross my fingers then!

Hi Solr Experts,
I am using the HTMLStripCharFilterFactory for removing tags in Body
element.
Body contains data like Ipad
I made changes in managed schema .

Working on that now to see if it helps us out. Solr process is NOT dying at
all. Searches are still working as expected, but since we load balance
requestsif the master/slave are out of sync the search results vary.
The advice is MUCH appreciated!

Restriction to a single shard seems like a big limitation for us.
Also, I was hoping that this was something Solr provided out of the box.
(Like

)
Something like:

I just discovered some odd behavior with aliases.
We are in the process of converting over to use aliases in solrcloud. We
have a number of collections that applications have referenced the
collections from when we used standalone solr. So we created alias names to
match the name that the java app
db order isn't generally defined, unless you are using an explicit "order
by" on your select. Default behavior would vary by database type and even
release of the database. You can index the fields that you would "order by"
in the db, and sort on those fields in solr

Another option is to have CDCR enabled for Solr and replicate your data to
another Solr cluster continuously.
BTW, why do we not recommend having Solr as a source of truth?

Why would you create an alias with an existing collection name?

I created the alias with an existing collection name because our code base
which was created with stand alone solr was a pain to change. I did test
that the alias took precedence over the collection, when I did a search.

Hi all,
We observe that solr query time increases significantly with the number of
rows requested, even all we retrieve for each document is just
fl=id,score. Debugged a bit and see that most of the increased time was
spent in BinaryResponseWriter, converting lucene document into
SolrDocument.
