Hi everyone,
If I have two server ,their indexes should be synchronized. I changed A's
index via HTTP send document objects, Is there any config or some plug-ins to
let solr know which objects are changed and can push it B ?
Any suggestion will be appreciate.

Nice article... 2 ms better than 20 ms, but in another chart 50 seconds are not

I have the following strange use case:
Index 100 documents and make them immediately available for search. I call
this "on the fly indexing". Then the index can be removed. So the size of
the index is not an issue here.
Is this possible with Solr? Anyone tried something similar?
Thank you,

Hi
You might also check the 'max_user_connections' settings too if you have that
set:
# Maximum number of connections, and per user
max_connections = 2048
max_user_connections = 2048

It seems that when I executed one delta-import command, several threads were
inserted into the table and removed after commit. Also it looks like the
number of threads are pretty much eq
Hi Bernd,

First get a heap dump with:

with 1234 being the PID (process id) of the JVM
After you get a Heap dump you can analyze
Thanks for your reply, Chandan.
Here is the additional information.
I'm also using the multi-core function, and I run the delta-import command
in parallel due to saving the running time. If I don't run in parallel, it
works fine. Each core accesses to the same database server but different
