SQL syntax error when executing MySQL script using Go during Heroku deployment

Asked 2021-Jun-05 at 15:15

I am deploying an API made using Go and MySQl for the database to Heroku. I am following this guide on it and set up everything but now I am trying to execute a MySQL script to set up the tables with some dummy data. But I am constantly getting errors saying that the script is wrong even though I have used it locally with no issues. I have already connected the MySQL database to the Heroku environment and starting the database throws no errors.

Here are the logs showing the error when deploying it to Heroku:

Ok so I decided to directly connect to the mysql database using the credentials given from Heroku.

This returns the URL to the database.

Django ORM key error with lost MySql connection

Asked 2020-Mar-15 at 19:25

This is the environment:

AWS Aurora database compatible with MySql.
Django 2.0.3 (Python 3.6)
Pip-Mysql dependencies: django-mysql==2.2.2, mysqlclient==1.3.12.
Master-Slave database configuration.

It seems that django or mysql engine always fails on certain queries resulting in this specific error:

Traceback (most recent call last): File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/django/db/models/fields/related_descriptors.py", line 158, in get rel_obj = self.field.get_cached_value(instance) File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/django/db/models/fields/mixins.py", line 13, in get_cached_value return instance._state.fields_cache[cache_name] KeyError: 'assigned_to'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/django/db/backends/utils.py", line 85, in _execute return self.cursor.execute(sql, params) File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 71, in execute return self.cursor.execute(query, args) File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/MySQLdb/cursors.py", line 253, in execute self._warning_check() File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/MySQLdb/cursors.py", line 148, in _warning_check warnings = db.show_warnings() File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/MySQLdb/connections.py", line 381, in show_warnings self.query("SHOW WARNINGS") File "/home/ubuntu/ivs/vpython/lib/python3.6/site-packages/MySQLdb/connections.py", line 277, in query _mysql.connection.query(self, query) _mysql_exceptions.OperationalError: (2013, 'Lost connection to MySQL server during query')

Yes, one of my models have "assigend_to" field which is a foreign key. But why does it fail with a KeyError?

Did anyone have any similar KeyErrors and MySql lost connections as a result?

In official MySQL definition, there is a specific page about this error. As can be seen from here in detail, here are what you should try:

The "during query" term in your error might be connected with a timeout caused by processing millions of rows. You can increase net_read_timeout to 60 seconds etc.
This can happen when you are trying the initial connection but in your case this is impossible.

QUESTION

Bulk MySQL Inserts are 2x Slower than PHP

Asked 2020-Jan-26 at 13:44

I've been testing Go in hopes to use it for a new site and wanted to make sure it was as fast or faster than PHP. So I ran a basic test doing bulk inserts in Go and PHP because I'll need bulk inserts.

My tests used transactions, prepared statements, the same machine, the exact same table definition, no index but the PK, and the same logic in the function.

Results:

100k Inserts in PHP (mysqli) was 4.42 seconds
100k Inserts in Go (Go-MySQL-Driver) was 9.2 seconds

The go mysql driver i'm using is the most popular one 'Go-MySQL-Driver' found here: https://github.com/go-sql-driver/mysql

I'm wondering if anyone can tell me if my code in go is not set up right or if this is just how go is.

The functions add a bit of variability to a few of the row variables just so every row isnt the same.

In my testing to find what language I want to use for my new website I experimented with php, golang, and java. I don't have much experience with any of the languages so anything I say here could be corrected by someone in the future.

My main test was batch inserts into the mysql database because I'll be needing it for an app.

I wanted to move away from php because it's a non-compiled old scripting language which is slower at many things than golang and java. It's also an awkward syntax for many things. However php mysqli is actually 2x faster than golang for large "transactions" unless you awkwardly spawn many go-routines to divide the work up.

During my testing and research I found out a few things.

The PHP mysqli "transactions" api are probably using some kind of batch operations to get a "transaction" done because mysqli has no separate batch functions and the transactions are quicker than single inserts. But in most other languages transactions don't auto-batch everything and don't even increase the execution time. They are just a mechanism to roll back everything in the transaction if something goes wrong. What increases execution time in other languages is using batches.

But one of the big problems with go mysql interface right now appears to be no real support for batch operations. The closest I got was to jerry rig one and make my own batch operation as pointed out by this post (golang - mysql Insert multiple data at once?). Doing this I was able to get the execution time in go from 9.2s to 3.9s without spawning other go routines. But since there's no real support for it the batch operation only returns a single result set for the first operation of the batch. This is worthless to me because I need to return autoinc Ids for my inserted rows. There were other problems with this setup too that I wont go into.

So lastly I tried java on a tomcat server. Tomcat/java installation is a bit more involved than go but programming in java was so much easier and natural. JDBC is an excellent driver with fulls support for easy batch operations with prepared statements. It did 100k inserts in only 1 sec. It's the clear winner in my book. Plus java syntax is much more natural than golang IMO.
