Transitioning From SQL Server to MySQL - Presentation from Percona Live 2016Dylan Butler

What if you were asked to support a database platform that you had never worked with before? First you would probably say no, but after you lost that fight, then what? That is exactly how I came to support MySQL. Over the last year my team has worked to learn MySQL, architect a production environment, and figure out how to support it alongside our other platforms (Microsoft SQL Server and Oracle). Along the way, I have also come to appreciate the unique offering of this platform and see it as an important part of our environment going forward. To make things even more challenging, our first MySQL databases were the backend for a critical, web based application that needed to be highly available across multiple data centers. This meant that we did not have the luxury of standing up a simpler environment to start with and building confidence there. Our final architecture ended up using a five node Percona XtraDB Cluster spread across three data centers. This session will focus on lessons learned along the way, as well as challenges related to supporting more than one database platforms. It should be interesting to anyone who is new to MySQL, anyone who is being asked to support more than one database platform, or anyone who wants to see how an outsider views the platform.

Scaling MySQL Using FabricRemote MySQL DBA

This document summarizes MySQL Fabric, an open-source tool from Oracle for sharding and managing high availability of MySQL databases at scale. It discusses how MySQL Fabric uses server groups, a fabric node, and fabric-aware connectors to partition data across shards and handle failures while providing a global view of the database schema and tables. Key features of MySQL Fabric mentioned include automated shard splitting and movement, minimized downtime during failures, and use of XML-RPC to avoid proxy hops between applications and shards.

Best practices for MySQL High AvailabilityColin Charles

The MariaDB/MySQL world is full of tradeoffs, and choosing a high availability (HA) solution is no exception. This session aims to look at all the alternatives in an unbiased way. Preference is of course only given to open source solutions. How do you choose between: asynchronous/semi-synchronous/synchronous replication, MHA (MySQL high availability tools), DRBD, Tungsten Replicator, or Galera Cluster? Do you integrate Pacemaker and Heartbeat like Percona Replication Manager? The cloud brings even more fun, especially if you are dealing with a hybrid cloud and must think about geographical redundancy. What about newer solutions like using Consul for MySQL HA? When you’ve decided on your solution, how do you provision and monitor these solutions? This and more will be covered in a walkthrough of MySQL HA options and when to apply them.

Getting started with Riak in the CloudInes Sombra

Getting started with Riak in the Cloud involves provisioning a Riak cluster on Engine Yard and optimizing it for performance. Key steps include choosing instance types like m1.large or m1.xlarge that are EBS-optimized, having at least 5 nodes, setting the ring size to 256, disabling swap, using the Bitcask backend, enabling kernel optimizations, and monitoring and backing up the cluster. Benchmarks show best performance from high I/O instance types like hi1.4xlarge that use SSDs rather than EBS storage.

Lessons from database failuresColin Charles

This is my third iteration of the talk presented in Tokyo, Japan - first was at a keynote at rootconf.in in April 2016, then at the MySQL meetup in New York, and now for dbtechshowcase. The focus is on database failures of the past, and how modern MySQL / MariaDB Server technologies could have helped them avoid such failure. The focus is on backups and verification, replication and failover, and security and encryption.

Performance outAndrea Martinez

Scaling out a web application involves adding redundancy, separating application tiers across multiple servers, implementing load balancing, caching content, and monitoring performance. Key aspects include mirroring disks for redundancy, moving services to separate application servers, using load balancing schemes like DNS round-robin or load balancers, solving session state issues through sticky routing or database storage, and caching dynamic content to improve performance. Monitoring the environment is also important to detect failures or bottlenecks as the infrastructure scales out.

Percona XtraDB ClusterKenny Gryp

Built-in MySQL Replication is known for its capability to enable to scale reads easily. However, there are some limitations and known issues with this solution because of the asynchronous nature of this replication. This talk will describe another way of doing MySQL replication, by using synchronous replication, available in Percona XtraDB Cluster. The open source solution will be explained and compared to traditional asynchronous MySQL replication, as well as some known use cases will be described. Percona XtraDB Cluster is an, open source, high availability and high scalability solution for MySQL clustering. Features include: Synchronous replication, Multi-master replication support, Parallel replication, Automatic node provisioning.

JavaOne2016 - Microservices: Terabytes in Microseconds [CON4516]Malin Weiss

Microservices can provide terabytes of data in microseconds by mapping data from SQL databases into in-memory key-value stores and column key stores within JVMs. This is done through periodic synchronization of changed data from databases into memory and mapping the in-memory data into fast access structures. The in-memory data is then exposed through Java Stream and REST APIs to microservices for high performance querying and analysis of large datasets. This architecture allows microservices to quickly share access to large datasets and restart rapidly by reloading from the synchronized persistent stores.

JavaOne2016 - Microservices: Terabytes in Microseconds [CON4516]Speedment, Inc.

By leveraging memory-mapped files, Speedment and the Chronicle Engine supports large Java maps that easily can exceed the size of your server’s RAM.Because the Java maps are mapped onto files, these maps can be shared instantly between several microservice JVMs and new microservice instances can be added, removed, or restarted very quickly. Data can be retrieved with predictable ultralow latency for a wide range of operations. The solution can be synchronized with an underlying database so that your in-memory maps will be consistently “alive.” The mapped files can be tens of terabytes, which has been done in real-world deployment cases, and a large number of micro services can share these maps simultaneously. Learn more in this session.

In-memory Caching in HDFS: Lower Latency, Same Great TasteDataWorks Summit

This document discusses in-memory caching in HDFS to improve query latency. The implementation caches important datasets in the DataNode memory and allows clients to directly access cached blocks via zero-copy reads without checksum verification. Evaluation shows the zero-copy reads approach provides significant performance gains over short-circuit and TCP reads for both microbenchmarks and Impala queries, with speedups of up to 7x when the working set fits in memory. MapReduce jobs see more modest gains as they are often not I/O bound.

8. Introduction To Galera • Founded By Codership • Synchronous Replication • Parallel Replication • Multi-Threaded • Automated node recovery • Zero slave lag • Read/ Write Scalable • WAN Based Optimization. • A True Open Source. 8

9. Introduction To Galera What is Galera ? Galera is a replication plugin for the synchronous and multi-master replication to achieve HA. “Wsrep_provider_options” controls library. Percona Cluster MariaDB Cluster Used over MySQL 9

10. Introduction To Galera • Shared nothing Architecture. • Network is the heart. What is wsrep ? (Write Set REPlication ) It is an API to connect the Galera library and control characteristics. It helps to implement synchronous replication and certification based multi-master- replication. 10

11. Introduction To Galera Simple Architecture 11

12. Percona Cluster • Use Galera Library • XtraDB • Xtrabackup + + 12

13. Percona Cluster Why Percona Server ? •Enhanced InnoDB (XtraDB ) •Performance Improvement •Xtrabackup ( Makes SST better ) •A better MySQL 13

14. Transaction in Galera. • Transaction is handled by Galera Plugin. • Uses traditional dual phase commit. • It also handles locking. • Uses the optimistic locking method. • The commits are based on certifications (keys). • Smaller transaction are always better. • Increase in network latency increases query time. 14

15. Transaction in Galera. 15

16. Transaction in Galera. • Synchronous ( Virtual ) Replication. • Wsrep_causal_reads=ON ( true synchronous) • Auto_increment is handled by cluster. • Uses GTID for Transaction. 16

17. Node Recovery 17 • Node recovery is automated. • Validates the gcache for state files. • Chooses the State Transfer method 1) IST (Incremental State Transfer) 2)SST (State Snapshot Transfer )

18. Node Recovery 18 IST : •Recover from write sets in gcache. •Faster recovery method. •Have good gcache size.

19. Node Recovery 19 SST : State Snapshot Transfer the complete transfer ( Cloning ) of data to recreate a node. *when not in Gcache *Adding a new node Different Methods of SST Xtrabackup (best ) , rsync , mysqldump .

20. Node Recovery 20 Validate Node after recovery Wsrep_local_state_Comment 1)Joining 2)Donor/desynced 3)Joined 4)Synced

21. Things should be considered. 21 • Support only Transactional engines. • Row Based replication. • Read commited Isolation. • Innodb_autoinc_lock_mode=2. • Avoid huge transactions. • Wsrep_max_ws_rows (128K) • Wsrep_max_ws_size. (1G) • Network is the heart. • Keep the DB design simple
