We added a second airflow database to support our staging airflow instance, and now both staging and production seem to have intermittent connection issues. We recently upgraded to 2.2.4, but looking through past RDS logs, I see aborted connections (Got an error reading communication packets) prior to the upgrade as well (previous version 1.10.11). Both instances have a webserver UI that pull in past DAG runs fine, and the scheduler is running DAGs appropriately and storing dag_run data. When the service is started however, we receive an error "MySQL server has gone away" (see below for stack trace). airflow db check and airflow db shell both return successful connections. Some relevant airflow config values are:
sql_alchemy_pool_enabled = True
sql_alchemy_pool_size = 5
sql_alchemy_max_overflow = 10
sql_alchemy_pool_recycle = 1800
sql_alchemy_pool_pre_ping = True
sql_alchemy_schema =
sql_alchemy_reconnect_timeout = 300
I've also tried upping the pool size to 20, and also confirmed that our db size should be able to handle at least 90 concurrent connections.

I am having problems using a MySQL database as a metadata database in a TensorFlow Extended pipeline.
I used the penguin template to set up a very simple pipeline and also set up a MySQL database locally.
The only thing I changed in the code was using
tfx.orchestration.metadata.mysql_metadata_connection_config as the metadata_connection_config input to the pipeline instead of tfx.orchestration.metadata.sqlite_metadata_connection_config
from tfx import v1 as tfx
# [...] Add a simple CsvExampleGen
tfx.dsl.Pipeline(
pipeline_name=pipeline_name,
pipeline_root=pipeline_root,
components=components,
metadata_connection_config=tfx.orchestration.metadata
.mysql_metadata_connection_config(
host="localhost",
port=3306,
database="ml_metadata",
username="root",
password="password"),
beam_pipeline_args=beam_pipeline_args,
)
Running this code results in the following error message:

How do I fix this ?
Thank to Martijn, I have fixed this.
In the source, stable 2.2 branch line 146 of django/db/backends/mysql/operations.py is
query = query.decode(errors='replace')
In my system path/to/virtualenv/django/db/backends/mysql/operations.py was like
# query = query.decode(errors='replace')
query = query.encode(errors='replace')
I changed it to
query = query.decode(errors='replace')
# query = query.encode(errors='replace')
It is working correctly now.

anyone happen to see same problem?Could you please give me some suggestion.
all ,nothing wrong with mysql, and Django. It's for I use a complex SQL to access mysql:
SELECT *
FROM
(SELECT *,
#batch_rank := IF(#current_batch = spider , #batch_rank + 1, 1) AS batch_rank,
#current_batch := spider
FROM deja_crawler.crawl_batch_record
where spider in (select distinct spider from deja_crawler.crawl_batch_record where spider like '%_new' or spider like '%_update')
ORDER BY spider, create_time DESC)
ranked
WHERE batch_rank <= 3
the tables used to have not too much data, so it works, later, the table became huge, and the access time cost is almost 30s, but the connection time out is set as 20s, so it will raise time out error.
I have an issue with my deployed application on an apache2 with mod_wsgi.
The connection process to the database is exactly successful only once out of 2!
I've named the database 'CKP' and for some reason have to change to 'ckp'.
So when I request a page of the application once out of two, I can read in the error log of apache:
mod_wsgi (pid=16098): Target WSGI script '/u1/msc/vg55/public_html/core_knowledge_web_platform/wsgi.py' cannot be loaded as Python module.

If it could help, I've integrated the improved WSGI script for use with Django given by Graham Dumpleton in his blog.
Thanks for any suggestion.
