Galera Cluster vs Percona: What are the differences?

## Introduction
Key differences between Galera Cluster and Percona are outlined below.

1. **Architecture**: Galera Cluster uses a virtually synchronous replication protocol that ensures data consistency across all nodes, whereas Percona utilizes an asynchronous replication protocol, which can lead to potential data inconsistencies.
2. **Conflict Resolution**: Galera Cluster employs a certification-based conflict resolution mechanism to resolve conflicts in data updates, while Percona relies on tools like Percona XtraDB Cluster to handle conflict resolution manually.
3. **Automatic Node Synchronization**: Galera Cluster automates the process of node synchronization, making it easier to add or remove nodes from the cluster, whereas Percona requires manual intervention for node synchronization.
4. **Data Distribution**: Galera Cluster stores a complete copy of the database on each node, ensuring high availability and fault tolerance, whereas Percona supports sharding techniques to distribute data across multiple nodes.
5. **Quorum Requirements**: Galera Cluster requires a majority of nodes to be available for write operations, ensuring data consistency, while Percona allows write operations even if not all nodes are accessible, which can result in inconsistencies.
6. **Support for Multi-Master Replication**: Galera Cluster natively supports multi-master replication, allowing multiple nodes to accept write transactions, whereas Percona requires additional configurations and tools for multi-master replication setups.

In Summary, the main differences between Galera Cluster and Percona include their architecture, conflict resolution mechanisms, node synchronization processes, data distribution techniques, quorum requirements, and support for multi-master replication. Each has its advantages and considerations for different clustering needs.

What are some alternatives to Galera Cluster, Percona?

MongoDB

MongoDB

MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.

MySQL

MySQL

The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.

PostgreSQL

PostgreSQL

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions.

dbForge Studio for MySQL

dbForge Studio for MySQL

It is the universal MySQL and MariaDB client for database management, administration and development. With the help of this intelligent MySQL client the work with data and code has become easier and more convenient. This tool provides utilities to compare, synchronize, and backup MySQL databases with scheduling, and gives possibility to analyze and report MySQL tables data.

Microsoft SQL Server

Microsoft SQL Server

Microsoft® SQL Server is a database management and analysis system for e-commerce, line-of-business, and data warehousing solutions.

SQLite

SQLite

SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file.

Cassandra

Cassandra

Partitioning means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.

Memcached

Memcached

Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

MariaDB

MariaDB

Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry. MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

dbForge Studio for Oracle

dbForge Studio for Oracle

It is a powerful integrated development environment (IDE) which helps Oracle SQL developers to increase PL/SQL coding speed, provides versatile data editing tools for managing in-database and external data.
