[ANNOUNCE] Apache CouchDB 2.1.0 released
Dear community, Apache CouchDB %VERSION% has been released and is available for download. CouchDB is a database that completely embraces the web. Store your data with JSON documents. Access your documents with your web browser, via HTTP. Query, combine, and transform your documents with JavaScript. CouchDB works well with modern web and mobile apps. You can distribute your data, efficiently using CouchDB’s incremental replication. CouchDB supports master-master setups with automatic conflict detection. CouchDB comes with a suite of features, such as on-the-fly document transformation and real-time change notifications, that make web development a breeze. It even comes with an easy to use web administration console, served directly out of CouchDB! We care a lot about distributed scaling. CouchDB is highly available and partition tolerant, but is also eventually consistent. And we care a lot about your data. CouchDB has a fault-tolerant storage engine that puts the safety of your data first. Download your copy here: https://couchdb.apache.org/#download Pre-built convenience binaries for Windows, macOS, Debian/Ubuntu and RHEL/CentOS are available. CouchDB 2.1.0 is a feature release, and was originally published on 2017-08-07. The community would like to thank all contributors for their part in making this release, from the smallest bug report or patch to major contributions in code, design, or marketing, we couldn’t have done it without you! The release notes follow. A formatted version of them can be viewed at http://docs.couchdb.org/en/2.1.0/whatsnew/2.1.html On behalf of the CouchDB PMC, Joan Touzet --- Version 2.1.0 The Mango _find endpoint supports a new combination operator, $allMatch, which matches and returns all documents that contain an array field with all its elements matching all the specified query criteria. New scheduling replicator. The core of the new replicator is a scheduler which allows running a large number of replication jobs by switching between them, stopping some and starting others periodically. Jobs which fail are backed off exponentially. There is also an improved inspection and querying API: _scheduler/jobs and _scheduler/docs: _scheduler/jobs : This endpoint shows active replication jobs. These are jobs managed by the scheduler. Some of them might be running, some might be waiting to run, or backed off (penalized) because they crashed too many times. Semantically this is somewhat equivalent to _active_tasks but focuses only on replications. Jobs which have completed or which were never created because of malformed replication documents will not be shown here as they are not managed by the scheduler. _replicate replications, started form _replicate endpoint not from a document in a _replicator db, will also show up here. _scheduler/docs : This endpoint is an improvement on having to go back and read replication documents to query their state. It represents the state of all the replications started from documents in _replicator db. Unlike _scheduler/jobs it will also show jobs which have failed or have completed. By default, scheduling replicator will not update documents with transient states like triggered or error anymore, instead _scheduler/docs API should be used to query replication document states. Other scheduling replicator improvements Network resource usage and performance was improved by implementing a shared connection pool. This should help in cases of a large number of connections to the same sources or target. Previously connection pools were shared only withing a single replication job. Improved request rate limit handling. Replicator requests will auto-discover rate limit capacity on targets and sources based on a proven Additive Increase / Multiplicative Decrease feedback control algorithm. Improved performance by having exponential backoff for all replication jobs failures. Previously there were some scenarios were failure led to continuous repeated retries, consuming CPU and disk resources in the process. Improved recovery from long but temporary network failure. Currently if replications jobs fail to start 10 times in a row, they will not be retried anymore. This is sometimes desirable, but in some cases, for example, after a sustained DNS failure which eventually recovers, replications reach their retry limit, stop retrying and never recover. Previously it required user intervention to continue. Scheduling replicator will never give up retrying a valid scheduled replication job and so it should recover automatically. Better handling of filtered replications. Failing user filter code fetches from the source will not block replicator manager and stall other replications. Failing filter fetches will also be backed off exponentially. Another improvement is when filter code changes on the source, a running replication will detect
[ANNOUNCE] Apache CouchDB 2.3.0 released
Dear community, Apache CouchDB 2.3.0 has been released and is available for download. Apache CouchDB™ lets you access your data where you need it. The Couch Replication Protocol is implemented in a variety of projects and products that span every imaginable computing environment from globally distributed server-clusters, over mobile phones to web browsers. Store your data safely, on your own servers, or with any leading cloud provider. Your web- and native applications love CouchDB, because it speaks JSON natively and supports binary data for all your data storage needs. The Couch Replication Protocol lets your data flow seamlessly between server clusters to mobile phones and web browsers, enabling a compelling offline-first user-experience while maintaining high performance and strong reliability. CouchDB comes with a developer-friendly query language, and optionally MapReduce for simple, efficient, and comprehensive data retrieval. https://couchdb.apache.org/#download Pre-built packages for Windows, macOS, Debian/Ubuntu and RHEL/CentOS are available. CouchDB 2.3.0 is a feature release, and was originally published on 2018-12-06. The community would like to thank all contributors for their part in making this release, from the smallest bug report or patch to major contributions in code, design, or marketing, we couldn’t have done it without you! See the official release notes document for an exhaustive list of all changes: http://docs.couchdb.org/en/stable/whatsnew/2.3.html Release Notes highlights: - (Multiple) Clustered purge is now available. This feature restores the CouchDB 1.x ability to completely remove any record of a document from a database. Conditions apply; to use the feature safely, and for full details, read the complete Clustered Purge documentation. - A new config setting is available, allowing an administrator to configure an initial list of nodes that should be contacted when a node boots up. Nodes in the seedlist that are successfully reached will be added to that node’s _nodes database automatically, triggering a distributed Erlang connection and replication of the internal system databases to the new node. This can be used instead of manual config or the cluster setup wizard to bootstrap a cluster. The progress of the initial seeding of new nodes is exposed at the GET /_up endpoint. - Replication supports ipv6-only peers. - The UUID of the server/cluster is once again exposed in the GET / response. This was a regression from CouchDB 1.x. - Stats counts between job runs of the replicator are no longer reset on job restart. - CouchDB’s _bulk_get implementation now supports the multipart/mixed and multipart/related content types if requested, extending compatibility with third-party replication clients. - CouchDB no longer forces the TCP receive buffer to a fixed size of 256KB, allowing the operating system to dynamically adjust the buffer size. This can lead to significantly improved network performance when transferring large attachments. - To improve security, there have been major changes in the configuration of query servers, SSL support, and HTTP global handlers. See the release notes for important upgrade information. - All python scripts shipped with CouchDB, including couchup and the dev/run development cluster script, now specify and require Python 3.x. - CouchDB is now compatible with Erlang 21.x. - The embedded version of rebar used to build CouchDB has been updated to the last version of rebar2 available. This assists in building on non-x86 platforms. - Plus many other performance improvements, bugfixes, and UI improvements! On behalf of the CouchDB PMC, Joan Touzet
