What Are Your Cloud Data Plans? Help Inform the Community, Take Percona’s Survey

Fill out a quick survey on your cloud data plans.

Today, keeping your enterprise agile and flexible is not just an advantage, it is a requirement. Many of the systems and processes once controlled by businesses onsite are moving offsite to “service” models. This includes Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), Database as a Service (DBaaS), etc.

These services are usually referred to as being in the cloud. The enterprise using the service doesn’t maintain or manage the infrastructure of the service in question.

Migrating database workloads to the cloud can be a vital part of improving customer experience, gaining deeper business insights and increasing efficiency. More enterprises are …

Demystifying Sequence Numbers (seqno) in Percona XtraDB Cluster

In this blog post, we’ll look at how sequence numbers work in Percona XtraDB Cluster.

Introduction

Percona XtraDB Cluster uses multiple sequence numbers (seqno), each having a special role to play. Let’s try to understand the significance of each sequence number.

global_seqno

An active Percona XtraDB Cluster cluster has multiple write-sets (transactions) generated from one or more nodes. These transactions then get replicated to other nodes of the cluster. Each write-set/transaction should have a unique identity across the cluster. global_seqno helps serve this identity. Given write-set will have the same global_seqno on …

Analytical Replication Performance from MySQL to Vertica on MemCloud

I’ve recently been trying to improve the performance of the Vertica replicator, particularly in the form of the of the new single schema replication. We’ve done a lot in the new Tungsten Replicator 5.3.0 release to improve (and ultimately support) the new single schema model.

As part of that, I’ve also been personally looking to Kodiak MemCloud as a deployment platform. The people at Kodiak have been really helpful (disclaimer: I’ve worked with some of them in the past). MemCloud is a high-performance cloud platform that is based on hardware with high speed (and volume) RAM, SSD and fast Ethernet connections. This means that even without any adjustment and tuning you’ve got a fast platform to work on.

However, if you are willing to put in some extra time, you can tune things further. Once you have a super quick …

Atomic Compound Statements

Atomic Compound Statements vaintroub_g Wed, 12/13/2017 - 16:39

Recently, we had a discussion about a hypothetical feature, "START TRANSACTION ON ERROR ROLLBACK", that our users would find very useful. It would allow sending several commands to the server in one batch (a single network packet), and let the server handle the errors. This would combine efficient network use, and atomic execution. It turns out that it is already possible to do this with MariaDB, albeit with a slightly different syntax.


To execute several statements, stmt1;.. stmtN, and rollback on error, we can use MariaDB Server 10.1's compound statement . Put a transaction inside it, combine it with an EXIT HANDLER, and here you are:

BEGIN NOT ATOMIC …

MySQL Enterprise Transparent Data Encryption (TDE) – provides at-rest encryption for physical InnoDB tablespace data files

With MySQL version 5.7.11 and up, Oracle continues to improve MySQL’s security features by adding MySQL Enterprise Transparent Data Encryption (TDE) for InnoDB tables stored in innodb_file_per_table tablespaces. This feature provides at-rest encryption for physical tablespace data files.

MySQL Enterprise TDE uses a two-tier encryption key architecture, consisting of a master encryption key and tablespace keys. When an InnoDB table is encrypted, a tablespace key is encrypted with the master key and the encrypted value of the tablespace key is stored in the tablespace header. When encrypting tablespace data, InnoDB transparently uses the master encryption key …
