Igniters, I'm happy to announce that the 5th alpha version of Ignite 3 is out!
On top of the functionality that was previously released, Alpha 5 adds the following major features: - Pluggable storages: ability to choose a specific storage for a table (RocksDB based storage, Page memory persistent and in-memory storage) with some known limitations. - Compute API (A simple remote job execution): The first phase of Compute API design and implementation. Of course, with known limitations. - Data colocation: The colocation key concept replaces the affinity key concept. DDL introduces COLOCATE BY clause. Colocated job execution. - Open API for the Ignite REST endpoints: A Specification to generate a client for any language + auto-generated docs for REST API. - Ignite REPL: The Ignite CLI as a REPL with autocompletion and improved UX. - Cluster lifecycle: It introduces cluster initialization logic and allows to specify cluster management and meta storage groups. Improved node join protocol. - Local and distributed recovery: Now it is possible to restart a cluster/node without data loss. - Data rebalance improvements (in progress and could be excluded from the release), including dynamically changing the number of partition replicas. - Robust client connection with seamless reconnection support and retry policies. - Java API for SQL: A simplified API for executing SQL queries on a cluster. Code examples have been added for the new features, you can check them out here: https://github.com/apache/ignite-3/tree/3.0.0-alpha5/examples The best way to try the release out is to go through the Getting Started Guide: https://ignite.apache.org/docs/3.0.0-alpha If there are any questions, issues, or thoughts, please do not hesitate to reply to this email.
