As MongoDB® has changed their license from AGPL to SSPL many are concerned by this change, and by how sudden it has been. Will SSPL be protective enough for MongoDB, or will the next change be to go to an altogether proprietary license? According to our poll, many are going to explore MongoDB alternatives. This blog post provides a brief outline of technologies to consider.

As announced in on October 18, we are ready for being part of following shows this week. Please come to find MySQL staff there and talk to us about MySQL.
A well-known performance booster in MySQL is to set sync_binlog to 0. However, this configuration alone comes with serious consequences on consistency and on durability (the C and D of ACID); I explore those in this series. In this post, I give some background on the sync_binlog parameter and I explain part of the problem with setting it to 0 (or to a value different from 1). The other
When running distributed database clusters, it is quite common to front them with load balancers. The advantages are clear - load balancing, connection failover and decoupling of the application tier from the underlying database topologies. For more intelligent load balancing, a database-aware proxy like ProxySQL or MaxScale would be the way to go. In our previous blog, we showed you how to run ProxySQL as a helper container in Kubernetes. In this blog post, we’ll show you how to deploy ProxySQL as a Kubernetes service. We’ll use Wordpress as an example application and the database backend is running on a two-node MySQL Replication deployed using ClusterControl. The following diagram illustrates our infrastructure:
Since we are going to deploy a similar setup as in …
[Read more]We’ll look into how Clickhouse allows us to ingest a large amount of data and run complex analytical interactive queries at MessageBird,. We also present the business needs that brought ClickHouse to our attention and detail the journey to its deployment. We cover the problems we faced, and how we dealt with them. We talk about our current Cloud production setup and how we deployed and use it.
We are really enthusiastic to share a use case of Clickhouse, how it helped us to scale our analytics stack with the good, the bad and the ugly.
The talk could be useful to newcomers and everyone wondering if Clickhouse could be useful to them.
What we’re looking forward to…
There are many talks, but these are among the top ones we’re looking forward to in particular:
The new release 8.0.13 for MySQL is available since last
week.
Concerning security, this comes with a new feature already
announced: the Password Verification Policy.
Let’s have a look…
This aim of this feature is to secure the attempts to change a
password by specifying the old one to be replaced.
It is turned off by default:
mysql> show variables like 'password_require_current'; +--------------------------+-------+ | Variable_name | Value | +--------------------------+-------+ | password_require_current | OFF | +--------------------------+-------+
and we can activate it by several ways (as for some other
password features):
1. Globally, at the server level:
mysql> set persist password_require_current='ON'; mysql> show variables like 'password_require_current'; +--------------------------+-------+ | Variable_name | Value | …[Read more]
