InfluxDB 0.9.3 has been released with significant improvements in write throughput, compression, and migration from version 0.8. The new release features a better than 2x improvement in peak write throughput and a better than 50% reduction in disk space compared to the previous version. The update also includes bug fixes and smaller features, but some breaking changes have been made, so it's recommended to carefully review the CHANGELOG before upgrading. The new release prioritizes addressing issues with write performance and compression, resulting in faster response times and reduced storage needs. However, sustained write load may still overwhelm the server eventually. Upgrading from previous versions requires careful consideration and potentially updating configuration files. Additionally, a migration path from version 0.8 is available, but some features are missing, including the TOP function and continuous queries. The release also includes early work on clustering, but it's not yet fully testable. Overall, InfluxDB 0.9.3 offers improved performance and storage efficiency, making it an attractive option for users who require high write throughput and data compression.
