OurSQL Episode 57: Eventual Discovery part 2

This week we continue our series on events. We talk about events and logging, event timing, privileges and runtime behavior.

Feedback
Gazzang is using encryptfs for their encryption. According to their launchpad project page at https://launchpad.net/ecryptfs, "eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux".

The main topic is the 2nd part of events:

What events log and where the event logs are
How errors show up in the error log
How events and their actions get logged to the binary logs (aka events and replication), including how the "ignore" and "do" replication limitations work with events. Manual page: http://dev.mysql.com/doc/refman/5.5/en/stored-programs-logging.html

OurSQL Episode 56: Eventual Discovery part 1

This week is all about events - events in MySQL, and calls for papers for 2012 conferences.

OurSQL Episode 53: MySQL 5.6 at OSCon Data

This week we speak with Calvin Sun, the Development Manager of the InnoDB Team, and has been working on InnoDB at MySQL and Oracle for 5 years. He mentions that not only is the InnoDB team hiring, but nobody has left the InnoDB team in several years, so the team is very stable.

We grabbed Calvin at OSCon Data, where Oracle announced the new features of MySQL 5.6 released on labs.mysql.com. Remember that the labs releases are for testing only and not supported in production use.

OurSQL Episode 52: Database Theory ABC

This week, we present ACID, BASE, CAP theorem and more.

At this year's Open Source Bridge in Portland last month, Eric Redmond presented 'A Dozen Databases in 45 minutes'. It’s really about 20 minutes of theory and 25 minutes of the dozen databases, and we present the first part, the theoretical side of things.

ACID - atomicity, consistency, isolation, durability
BASE- basically available, soft state, eventual consistency (there's also a good article by Lewis Cunningham that explains ACID vs. BASE in the context of cloud computing.

OurSQL Episode 46: It's About Time

This week we talk about time formats and time zones in MySQL - including how changing the system time changes TIMESTAMP values but not DATETIME values. We also talk about how to handle and store microseconds in MySQL.

From the MySQL manual:
date and time types
TIMESTAMP properties and how it is stored in UTC transparently in the database
ALLOW_INVALID_DATES sql_mode

OurSQL Episode 44: Elemental Replication (Tungsten, that is)

Last week's podcast, containing an overview of replication

This week we have Robert Hodges, CEO of Continuent, talking about the Tungsten replicator, which has an open source component with global transaction id's and can be used for many features, including high availability and replication to systems other than MySQL. Tungsten Replicator won Application of the Year award at the 2011 O'Reilly MySQL Conference.

OurSQL Episode 42: The Buzz about MySQL 5.6

This week we talk about what's new in MySQL 5.6 and the return of labs.mysql.com. We also feature people's reactions to the 5.6 announcement and a special song by Solomon Chang (lyrics below).

Show notes:
If you want to see it for youreslf, there is a video from the O'Reilly Conference of Tomas Ulin's Keynote, "State of the Dolphin".

Olav Sandstå's blog post on index condition pushdown optimization.

OurSQL Episode 40: TokuDB 5.0 part 2

This week we conclude the interview with Tokutek's co-founder and Chief Scientist, Martin Farach-Colton. Part 1 of the interview. TokuDB is a transactional, fully ACID-compliant storage engine that uses fractal trees for data and indexes, instead of MySQL's standard B-tree implementation. Combined with TokuDB's message-based architecture, TokuDB data and indexes do not fragment, have completely online column and index addition and removal and unlike InnoDB and XtraDB, do not fall apart when indexes no longer fit into memory.
