- But I have not run it on CGSpace yet because we want to ask Peter if he is sure about it...

|

|
||||
- I found a very [interesting comment on the Solr 8.1 guide](https://lucene.apache.org/solr/guide/8_1/solr-system-requirements.html#lucene-solr-prior-to-7-0) about Java compatibility:
|
||||
|
||||
> Lucene/Solr 7.0 was the first version that successfully passed our tests using Java 9 and higher. You should avoid Java 9 or later for Lucene/Solr 6.x or earlier.

|
||||
|
||||
- I want to try to consolidate our yearly Solr statistics cores back into one `statistics` core using the solr-import-export-json tool
|
||||
- I will try it on DSpace test, doing one year at a time:
|
||||
|
||||
```
|
||||
$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o /tmp/statistics-2010.json -k uid
|
||||
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o /tmp/statistics-2010.json -k uid
|
||||

|
||||

|
||||

||||

```
|

- I will do this for as many cores as I can (disk space limited) and then monitor the effect on the system and JVM memory usage
