As data and processing wants have grown, ache factors equivalent to efficiency and resiliency have necessitated new options. Databases want to keep up ACID compliance and consistency, present excessive availability and excessive efficiency, and deal with large workloads with out turning into a drain on assets. Sharding has provided an answer, however for a lot of firms sharding has reached its limits, resulting from its complexity and useful resource necessities. A greater answer is distributed SQL.
In a distributed SQL implementation, the database is distributed throughout a number of bodily programs, delivering transactions at a globally scalable stage. MariaDB Platform X5, a serious launch that features upgrades to each facet of MariaDB Platform, gives distributed SQL and large scalability by way of the addition of a brand new good storage engine referred to as Xpand. With a shared nothing structure, totally distributed ACID transactions, and robust consistency, Xpand lets you scale to tens of millions of transactions per second.
Optimized pluggable good engines
MariaDB Enterprise Server is architected to make use of pluggable storage engines (like Xpand) to optimize for specific workloads from a single platform. There isn’t any want for specialised databases to deal with particular workloads. MariaDB Xpand, our good engine for distributed SQL, is the latest addition to our lineup. Xpand provides massively scalable distributed transactional capabilities to the choices supplied by our different engines. Our different pluggable engines present optimization for analytical (columnar), read-heavy workloads, and write-heavy workloads. You can combine and match replicated, distributed, and columnar tables to optimize each database on your particular necessities.
Adding MariaDB Xpand allows enterprise prospects to realize all the advantages of distributed SQL – pace, availability, and scalability – whereas retaining the MariaDB advantages they’re accustomed to.
Let’s take a high-level have a look at how MariaDB Xpand gives distributed SQL.
Distributed SQL right down to the indexes
Xpand gives distributed SQL by slicing, replicating, and distributing knowledge throughout nodes. What does this imply? We’ll use a quite simple instance with one desk and three nodes to display the ideas. Not proven on this instance is that every one slices are replicated.

In Figure 1 above, now we have a desk with two indexes. The desk has some dates and now we have an index on column 2, and…
