InfluxDB, an open-source time series database, has introduced new features in its version 1.2 CLI that require users to explicitly set the target retention policy for writes. This change aims to improve clarity and consistency in data management. Additionally, querying a retention policy can be tricky, as the default behavior is not always what it seems. Users are advised to clear any existing retention policies before setting new ones. InfluxDB also emphasizes the importance of security, recommending users check out its Security Best Practices pages for tips on keeping their data secure when installing with public internet access.
