Solr-8.11.2 Import of Large Data Issue

[Anuj Bhargava]

I am using solr-8.11.2. My MySql table has 13001335 which is around 259.9
GB.

solr.in.sh has the following entry -
SOLR_JAVA_MEM="-Xms15g -Xmx15g"
SOLR_OPTS="$SOLR_OPTS -Dsolr.disable.shardsWhitelist=true"


<dataConfig>
<dataSource type="JdbcDataSource"
            driver="com.mysql.jdbc.Driver"
            batchSize="-1"
            autoReconnect="true"
            useSSL="false"
            socketTimeout="0"
            connectTimeout="0"
            encoding="UTF-8"

url="jdbc:mysql://xxx.xxx.xx.xxx:3306/archive_dbase?zeroDateTimeBehavior=convertToNull"
            user="archive_user"
            password="password66"/>
<document>
<entity name="newarchive" pk="ID"
  query="SELECT * FROM newarchive"
  deltaImportQuery="SELECT * FROM newarchive
    WHERE posting_id = '${dataimporter.delta.posting_id}'"
  deltaQuery="SELECT posting_id FROM newarchive
    WHERE Deadline > '${dataimporter.last_index_time}'">
</entity>
</document>
</dataConfig>

Whenever I import the MySql stops after sometime and then restarts. Not all
records are imported. What changes do I need to make?
