### solr-import-export-json

# Import/Export (or Restore/Backup) a Solr collection from/to a json file.

As the title states, this little project will help you to save your collection in json format and restore it where and when you need.

Please report issues at https://github.com/freedev/solr-import-export-json/issues

### Install

#### Download a pre-built release (recommended)

Pre-built releases are available on the [GitHub Releases page](https://github.com/freedev/solr-import-export-json/releases).
Each release is tagged with the app version and the Solr version it was built against (e.g. `v1.1-solr9.10.0`), so you can pick the one that matches your Solr installation.

You only need Java 17 or later installed to run it:

sudo apt update
    sudo apt install openjdk-17-jdk

Download the JAR for your Solr version and you're ready.

#### Build from source

To build from source you need Java 17, git and Maven. On Linux:

sudo apt update
    sudo apt install git openjdk-17-jdk maven
  
    git clone https://github.com/freedev/solr-import-export-json.git
    cd solr-import-export-json
    mvn clean package

Now you're ready.

### Real life examples

export all documents into a json file

./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json

import documents from json

./run.sh -s http://localhost:8983/solr/collection -a import -o /tmp/collection.json

export part of documents, like adding a few `fq`  Solr parameters to the export

./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json --filterQuery field1:A  --filterQuery field2:B

import documents from json but first delete all documents in the collection

./run.sh -s http://localhost:8983/solr/collection -a import -o /tmp/collection.json --deleteAll

export documents and skip few fields. In the example the will be skipped the fields: `field1_a`, all the fields starting with `field2_` and all the fields ending with `_date`

./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json --skipFields field1_a,field2_*,*_date

Import documents, skip first 49835000 records from file, commit every 200000 documents, block size 5000 (faster than default 500)

./run.sh -s http://localhost:8983/solr/collection -a import -o /tmp/collection.json -x 49835000 -c 200000 -b 5000
