Then secretary of Defense Donald Rumsfeld popularized the terms: “known knowns”, “known unknowns”, and “unknown unknowns.” With the ever-increasing number of data breaches and vulnerabilities, database operation teams have to account for every possibility. Visualizing your audit data allows you to look for the “unknowns”, those access patterns or connections that you’d otherwise overlook.

Although enabling an audit log and shipping it off to a vault may meet security and regulatory requirements, you will lose an important opportunity to protect your customer and employee information.

The following dashboard demonstrates the type of information that audit logs can reveal:

• Who is connecting to my database (IP address, location, username..)
• Who is trying to connect to my database but getting access errors?
• Which tables are being accessed and by whom?
…

Ready to transition from a commercial database to open source, and want to know which databases are most popular in 2019? Wondering whether an on-premise vs. public cloud vs. hybrid cloud infrastructure is best for your database strategy? Or, considering adding a new database to your application and want to see which combinations are most popular? We found all the answers you need at the Percona Live event last month, and broke down the insights into the following free trends reports:

• Top Databases Used: Open Source vs. Commercial
• Cloud Infrastructure Analysis: Public Cloud vs. On-Premise vs. Hybrid Cloud
• Polyglot Persistence Trends: …

Wondering which databases are trending in 2019? We asked hundreds of developers, engineers, software architects, dev teams, and IT leaders at DeveloperWeek to discover the current NoSQL vs. SQL usage, most popular databases, important metrics to track, and their most time-consuming database management tasks. Get the latest insights on MySQL, MongoDB, PostgreSQL, Redis, and many others to see which database management systems are most favored this year.

SQL vs. NoSQL

As any database administrator knows, the first question you have to ask yourself is whether to use a SQL or NoSQL database for your application. …

For Percona Live Europe, I’ll be presenting the tutorial Elasticsearch 101 alongside my colleagues and fellow presenters from ObjectRocket Alex Cercel, DBA, and Mihai Aldoiu, Data Engineer. Here’s a brief overview of our tutorial.

Elasticsearch® is well known as a highly scalable search engine that stores data in a structure optimized for language based searches but its capabilities and use cases don’t stop there. In this tutorial, we’ll give you a hands-on introduction to Elasticsearch and give you a glimpse at some of the fundamental concepts. We’ll cover various administrative topics like …

We had a great webinar on Wednesday looking at how we can use Tungsten Replicator for moving data into Elasticsearch, whether that’s for analytics, searching, or reporting.

You can ahead and watch the video recording of that session here

We had one question on that session, which I wanted to answer in full:

Can UPDATE and DELETE be converted to INSERT?

One of the interesting issues with replicating databases between databases is that we don’t always want the information in the same format when it goes over another side. Typically when replicating within a homogeneous environment the reason we are using replication is that we want an identical copy over on the other side of the process. In heterogeneous, especially when we move the data out to an analytics environment like Elasticsearch, we might not. That covers a whole range of …

You may know Continuent Tungsten for our highly advanced MySQL replication tool, Tungsten Replicator, and for our state-of-the-art MySQL clustering solution, Tungsten Clustering. Our solutions are used by leading SaaS vendors, e-commerce, financial services and telco customers.

But there are more, many more, Tungsten deployments out there. Tungsten Replicator can be used for real-time data

Continuent are pleased to announce the release of Tungsten Replicator and Tungsten Clustering 5.2.0

This release is one of our most exciting new releases for a while, as it contains some significant new features and lays the groundwork for some additional new functionality in the upcoming 5.3.0 and 6.0 releases due later this year.

In particular, this release includes the following new features:

• New replicator filtering environment to make filtering quicker and easier to use, and more flexible
  • New filter configuration standard for new filters
  • New filter to make replication out of a cluster easier
  • New filters for filtering events and data
• New applier for sending Apache Kafka messages directly from an incoming data stream
• New applier for adding incoming records directly to Elasticsearch for indexing
• New …

So here at Continuent we are working on multiple new targets for applying data using Tungsten Replicator. There are so many potential targets out there where people want to replicate data directly into a specific system, sometimes just for a specific data set, table, database or requirements.

Yesterday afternoon, I started working on ElasticSearch – this morning I have it finished!

As with all solutions, the same basic principles apply – want to pull out of MySQL or Oracle and into something else? That’s fine. Want to replicate to HDFS and ElasticSearch? We do that too!

So what does it look like?

Installation operates just our normal appliers – you just specify the datasource type (ElasticSearch) and the EL host name and port:

tools/tpm configure alpha \
--datasource-type=elasticsearch \
--install-directory=/opt/continuent \ …
