Mysql free edition limitations

Redis and Memcached are primarily in-memory key-value stores. All three solutions partition and cache data in memory and they can be scaled out across distributed clusters. However, there are many differences in the way caching, transactions, persistence, and data querying are supported. The Apache Ignite in-memory computing platform includes many additional features not in Redis or Memcached that are often highly valuable for companies moving to in-memory computing.

In thousands of updates per second are applied to a single database row for example, flash online sales for high-demand concert tickets , it is crucial to maintain exact values at every second.

MySQL is designed around full transactional semantics with support for long transactions and works with disk-based log durability.

It is therefore not well suited for use with this kind of highly volatile data. Splitting the counter over several rows can help, and optimal configuration of the MySQL installation can yield up to ten times better performance than a stock MySQL configuration. Parallel replication, another historical problem, has been addressed in MySQL 5. A Better Solution: Apache Ignite automatically distributes data across all nodes in a cluster.

Replication between nodes and clusters is configurable and takes place automatically. Apache Ignite can be configured to provide the needed level of consistency. The Apache Ignite in-memory computing platform also includes many additional features not included in Percona XtraDB Cluster, Redis or Memcached that are often highly valuable for companies that are moving to in-memory computing.

MySQL was originally designed as a single-node system and not with the modern data center concept in mind. However, most sharding solutions in MySQL are manual and make application code more complex. Any performance gain is lost when queries must access data across multiple shards. A Better Solution: Apache Ignite was built from the ground up as a high performance and highly scalable distributed in-memory computing platform. There are no limitations to the amount of CPU and memory that can be used by any node.

Furthermore, nodes are automatically load balanced. Data is automatically distributed across all nodes in a cluster so manual sharding is not necessary. Apache Ignite is a complete in-memory computing platform that includes many additional features beyond those offered by point solutions such as Vitess, Redis, Memcached, MongoDB, and Cassandra.

MySQL was not designed for running complicated queries against massive data volumes which requires crunching through a lot of data on a huge scale. MySQL optimizer is quite limited, executing a single query at a time using a single thread.

A given MySQL query can neither scale among multiple CPU cores in a single system nor execute distributed queries across multiple nodes. Vertica and ClickHouse have also emerged as worthy analytics solutions. A Better Solution: Apache Ignite easily integrates with Hadoop and Spark, using in-memory technology to complement these technologies and achieve significantly better performance and scale.

MySQL can handle basic full text searches. However, because of its inability to manage parallel processing, searches do not scale well as data volumes increase. The following would be our daily transactional activity with the DB Atleast 10 million records would be created and updated on a person day basis. Thanks in Advance. Community Bot 1 1 1 silver badge.
