Hi,

I want to do index mysql data with ES(2.3.3). I am using Mysql and php platform now.  
My data size is 600.000.000 and I can't do index. My error:

`Got a packet bigger than 'max_allowed_packet' bytes`

I changed max\_allowed\_packet=1G in my.cnf but it didn't index.

What can I do? how much indexed data limit should be ? Is there such a limit?

This is a MySQL question in Elasticsearch discussion, you can not expect many answers.

Consider the following:

- the data size has nothing to do with `max_allowed_packet`. There is no practical limit.
- the default `max_allowed_packet` can be viewed with `show variables like 'max_allowed_packet'` in MySQL client.
- Increase number carefully. A number too high will have massive impact on your system, it will not work any more. Maximum should be around `16M`. `1G` is much too high.
- you have to change it on both client and server. Check MySQL documentation how to do that [https://dev.mysql.com/doc/refman/5.7/en/packet-too-large.html](https://dev.mysql.com/doc/refman/5.7/en/packet-too-large.html)
