If you have a business no matter how small, you are collecting data, and you need to have your data accessible to make informed decisions about how to make your business better. The more successful you become the more data you are producing and the more you become dependent by it. This is when you start to realize your must have your data in a safe place like a database instead some spreadsheet.

But to put your data in a database is not enough, you must be sure the database will be robust, resilient, and always available when you or your customers need it.

When design architectures for robust database architectures, we always discuss about High Availability (HA) and Disaster Recovery (DR). These two concepts are elements of the larger umbrella that is the Business continuity plan.

To cover the different needs, we (Database Architects) use/apply two main models: Tightly Coupled cluster, and Loosely Coupled cluster (latest …

X Protocol traffic compression is available on MySQL Server since version 8.0.19. A connector that also supports compression on its end can leverage this feature and reduce the byte streams that are exchanged with the Server.

By default, connections to a MySQL server are uncompressed, thus permitting exchanging data with a client or connector that doesn’t support compression. However, given a client or connector that also supports compression, it is recommended that client and server negotiate the connection compression by default. If this negotiation concludes successfully, both ends can then compress the data they send.

Compression at this level allows reducing the amount of bytes exchanged over the network, but at the cost of additional CPU resources required to run data inflate and deflate operations. The benefits of compression, therefore, occur primarily on low network bandwidth. One can assess the gain or loss due to the …

Dear MySQL users,

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.22, is a maintenance release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see

In version 8.0.22 we have added a number of important new features. The first

one is that we introduced the capability to create encrypted backups.

This includes capabilities to create encrypted backups, restore encryped

backups and also encrypt backups that was created without encryption.

The second is that we have added support for IPv6 addresses.  If it is

necessary to mix IPv4 and IPv6 addresses in a cluster it is important

to be careful and follow a number of rules as documented.

Performance of replication of BLOB columns has been significantly

improved and similarly for SELECT statements using BLOB columns.

This has been achieved through decreasing the amount of round-trips used

to perform operations involving BLOB tables. This significantly decreases

the latency of operations involving BLOBs.
