MySQL Backup Strategies and Tools – MinervaDB Webinar

MinervaDB Webinar – MySQL Backup Strategies and Tools 

Most often Database Systems outages happen due to user error and it is also the biggest reason for data loss / damage or corruption. In these type of failures, It is application modifying or destroying the data on its own or through a user choice. Hardware failure also contributes to database infrastructure crashes and corruption. To address these sort of data reliability issues, you must recover and restore to the point in time before the corruption occurred. Disaster Recover tools returns the data to its original state at the cost of any other changes that were being made to the data since the point the corruption took place. MinervaDB founder and Principal, hosted a webinar (Thursday, June 18, 2020 – 06:00 PM to 07:00 PM PDT) on MySQL backup strategies and tools addressing the topics below:

  • Proactive MySQL DR – From strategy to execution

Advanced Query Tuning in MySQL 5.6 and MySQL 5.7 Webinar: Q&A

Thank you for attending my July 22 webinar titled “Advanced Query Tuning in MySQL 5.6 and 5.7” (my slides and a replay available here). As promised here is the list of questions and my answers (thank you for your great questions).

Q: Here is the explain example:

mysql> explain extended select id, site_id from test_index_id where site_id=1
*************************** 1. row ***************************
           id: 1
  select_type: SIMPLE
        table: test_index_id
         type: ref
possible_keys: key_site_id
          key: key_site_id
      key_len: 5
          ref: const
         rows: 1
     filtered: 100.00
        Extra: Using where; Using index

why is site_id a covered index for the query, given the fact that a) we are selecting “id”, b) key_site_id only …

Considering Sharding with MySQL? Join my April 22 webinar. Questions welcome!

MySQL sharding is one of the most used and surely the most abused MySQL scaling technology. My April 2 Dzone article, “To Shard, or Not to Shard,” proved there is indeed quite an interest in this topic.

As such, I’m hosting a live webinar tomorrow (April 22) that will shed light on questions about sharding with MySQL. It’s titled: To Shard or Not to Shard That is the Question!

I’ll be answering questions such as:

  • Is sharding right for your application or should you use other scaling technologies?
  • If you’re sharding, what things do you need to consider and which questions do you need to have answered?
  • What kind of specific technologies can assist you with sharding?

I hope …

Q&A: Multi-threaded Replication in MySQL 5.6 and MySQL 5.7

My webinar “Multi-threaded Replication in MySQL 5.6 and 5.7″ on February 25 generated several excellent questions following the presentation (available here for playback along with the slides). I didn’t have time to answer many of the questions during the session and so in this post I answer all of them. Thanks to everyone who attended!

Q: What do you expect from MTS with logical clock? Do you think performance would be good as with per database?
A: MTS with 5.6 is not usable if you have a single database. I do not have numbers, but this is quite frequent. With 5.7 everyone should be able to benefit from multi-threaded replication.

Q: When MySQL 5.6 was released, performance of MTS was lower, than in 5.5, for example. Is this addressed now?
A: I am not sure which …
