Postgres-XL 9.5 R1.4 Announced!

The Postgres-XL community is pleased to announce a security update of the software, tagged as 9.5R1.4. Besides bug fixes, this release catches up with the community release of PostgreSQL 9.5.5 including all the core server’s security & bug fixes. We encourage everyone to immediately upgrade to this latest release. Being a minor release, you only need to download the latest sources from, compile, install new binaries and restart your servers. Please note, there was a slight change to the on-disk representation of views/rules in R1.2, so if you’re upgrading from pre-1.2 release, you will need to do a fresh initdb or recreate the failing objects. Upgrading from R1.2 to a later release should not require initdb. For more details, please refer to the release notes...

Postgres-XL 9.5 R1 Released!

The Postgres-XL community is pleased to announce the 1st release of Postgres-XL 9.5. This release has been fully synced up till PostgreSQL 9.5.2.   Postgres-XL is a massively parallel database built on top of, and very closely compatible with PostgreSQL 9.5 and its set of advanced features. Postgres-XL is fully open source and many parts of it will feed back directly or indirectly into later releases of PostgreSQL, as we begin to move towards a fully parallel sharded version of core PostgreSQL. Postgres-XL is different because it supports both Business Intelligence and OLTP workloads in the same horizontally scalable server. This allows Postgres-XL to support a diverse range of workloads OLTP workloads that need write-scalability as well as read-scalability Business Intelligence requiring OLAP with massive parallelism Operational Data Store/ Central Data Backbone Distributed Key-Value store using JSONB, similar to NoSQL Internet of Things applications Mixed-workload environments Star schema style SQL queries exhibit large performance gains from massively parallel processing (MPP). Many queries show fully linear performance gains, for example a 16-node XL cluster is 16 times faster than PostgreSQL on one node. Postgres-XL is able to successfully complete the complex TPC-H business intelligence benchmark, showing its capability to address much more than basic operations. Besides proving its mettle on Business Intelligence workloads, Postgres-XL has performed remarkably well on OLTP workloads when running pgBench (based on TPC-B) benchmark. In a 4-Node (Scale: 4000) configuration, compared to PostgreSQL, XL gives up to 230% higher TPS (-70% latency comparison) for SELECT workloads and up to 130% (-56% latency comparison) for UPDATE workloads. Yet, it can scale much, much higher than even the...
