This is your weekly summary of Compose news for those changes and updates which can make your life easier. In this edition, the latest upgrades for your databases, a change to Write Stuff and a look back at the past week's articles.
MongoDB 3.4.10 and Elasticsearch 6.2.2
Last week saw the arrival of two major updates to the databases available on Compose. MongoDB users on Compose can configure or upgrade to MongoDB 3.4.10 which adds read-only views, aggregation graph lookups, buckets, facets and array operations to the popular NoSQL database. Also new is support for high precision decimal types.
Elasticsearch users can also upgrade from previous versions up to the latest Elasticsearch, 6.2.2. This update builds on Elasticsearch 5.x to give a more reliable, faster platform for doing complex search and indexing. Elasticsearch 6 also sees the start of the end for the databases ability to map multiple types to a single index, a change which will open the way to better performance by simplifying the data model for general use.
Both new versions are available now. Upgraders should consult the announcements and documentation for guidance on migration.
Compose's Write Stuff program is designed to help those people with a technical knowledge of databases turn that knowledge into readable, useful articles. The programme runs on cycles and to make things easier and less time-pressured, we've doubled the length of the cycles, so the current one now ends May 31st.
