## Overview
- Tool for testing elastic (ES, formerly elastic search) instance by storing `No-SQL` JSON documents by index (ES / Kibana instance setup required).

## Technologies Used
- JDK 25, Elastic 9 (formerly ElasticSearch), & JEST Client 6

# Program Arguments
```shell
<elastic-search-instance-url> <index> <elastic_username> <elastic_password> <inserts_needed>
```

## Build Project
```shell
./mvnw clean compile assembly:single
```

## Usage Example
```shell
java -Djavax.net.ssl.trustStore=$TRUSTSTORE \
    -Djavax.net.ssl.trustStorePassword=$TRUSTPASS \
    -cp target/elastic-search-tester-3.6.5-RELEASE-jar-with-dependencies.jar net.ironoc.elastic.ElasticApp \
    "https://localhost:9200/" test_index elastic $ELASTIC_PASSWORD false
```
