Faceted search or faceted navigation is a highly praised and widely use search pattern. And, it is a great reply to an off the records sales engineering question. MySQL finally has some document store features built-in. A bit of a yawn in 2016. There is a new X DevAPI available with some Connectors. A bit of a yawn technically. But it is a non-technical change of mind: developer centric counts! Sales, all, technical value could show at non-trivial developer tasks, like faceted search.

Todays X DevAPI does not get you very far

There are great stories to tell about the X …

This year at Etsy, we spun up a “Database Working Group” that talks about all things data. It’s made up of members from many teams: DBA, core development, development tools and data engineering (Hadoop/Vertica). At our last two meetings, we started talking about how many “sources of information” we have in our environment. I hesitate to call them “sources of truth” because in many cases, we just report information to them, not action data based on them. We spent a session whiteboarding all of of these sources and drawing the relationships between them. It was a bit overwhelming to actually visualize the madness.

A few examples:

• We use Chef for configuration management and Chef knows about all database server. It made sense for us to build out our monitoring to generate Nagios configuration based on that data from Chef. When …

If you remove a file, file system generally just marks in its metadata that previously occupied blocks can now be used for other files – that operation is usually cheap, unless the file has millions of segments (that is such a rare case, only seen in experimental InnoDB features that Oracle thought was a good idea).

This changes a bit with SSDs – if you update underlying device metadata, it can have smarter compaction / grooming / garbage collection underneath. Linux file systems have ‘discard’ option that one should use on top of SSDs – that will extend the life time of their storage quite a bit by TRIM’ing underlying blocks.

Now, each type of storage device will react differently to that, some of them support large TRIM commands, some of them will support high rate of them, some of them won’t, etc – so one has to take that into account when removing files in production environments.

Currently Linux block …

“Leading enterprises have a firm grasp of the technology edge that’s relevant to them. Better data analysis and disambiguation through semantics is central to how they gain competitive advantage today.”–Alan Morrison.

I have interviewed Alan Morrison, senior research fellow at PwC, Center for Technology and Innovation.
Main topic of the interview is how the Big Data market is evolving.

Q1. How do you see the Big Data market evolving? 

Alan Morrison: We should note first of all how true Big Data and analytics methods emerged and what has been disruptive. Over the course of a decade, web companies have donated IP and millions of lines of code that serves as the foundation for what’s being built on top.  In the …

MySQL 5.7 makes secure connections easier with streamlined key generation for both MySQL Community and MySQL Enterprise, improves security by expanding support for TLSv1.1 and TLSv1.2, and helps administrators assess whether clients are connecting securely or not with new visibility into connection types.  Extending this emphasis on secure connections, MySQL Server 5.7 introduces a new server-side configuration option allowing MySQL administrators the ability to restrict connections …

Hortonworks went to use the lessons to create a fresh database, partnering program, which has become called PostgreSQL. InfiniDB’s paper was likewise read and Hortonworks SQL was designed in the mid-2000s at Uppsala University. In 2010, this job was combined into an independent business. InfiniDB introduced trade management in programs, a notion which was later […]

At Etsy, we have a nice, clean, streamlined build process. We have a command for setting up RAID, and another for OS installation. OS installation comes with automagic for LDAP, Chef roles, etc.

We came across an odd scenario today when a co-worker was building a box that gave the following error:

Traceback (most recent call first): File “/usr/lib/anaconda/storage/partitioning.py”, line 1066, in allocatePartitions disklabel = disklabels[_disk.path] File “/usr/lib/anaconda/storage/partitioning.py”, line 977, in doPartitioning allocatePartitions(storage, disks, partitions, free) File “/usr/lib/anaconda/storage/partitioning.py”, line 274, in doAutoPartition exclusiveDisks=exclusiveDisks) File “/usr/lib/anaconda/dispatch.py”, line 210, in moveStep rc = stepFunc(self.anaconda) File “/usr/lib/anaconda/dispatch.py”, line 126, in gotoNext self.moveStep() File “/usr/lib/anaconda/dispatch.py”, line 233, in …

I really like Amazon.com and I have been a Prime member for several years. Along with millions of different items for sale, Amazon has an affiliate program, where you can earn money advertising products on your web site. When a visitor to your site clicks on a link and orders a product from Amazon, you earn a small commission on the total sale. As an affiliate, you have access to Amazon’s Product Advertising API for obtaining product information. But, you can use this information for many other purposes.

The Amazon API is like most other API’s, and their API web site provides you with code examples and explains how it all works. I am going to show you how a Perl program which you can use to access the API data and store it in a …
