Beta expectations and recommendations

InfluxDB Core and Enterprise relationship

InfluxDB 3 Enterprise is a superset of InfluxDB 3 Core. All updates to Core are automatically included in Enterprise. The Enterprise sections below only list features exclusive to Enterprise.

v0.1.0 Beta

Core

Features

  • Query and storage enhancements

    • New ability to stream response data for CSV and JSON queries, similar to how JSONL streaming works.
    • Parquet files are now cached on the query path, improving performance.
    • Query buffer is incrementally cleared when snapshotting, lowering memory spikes.

  • Processing engine improvements

    • New scheduled trigger enables Python plugins to run on a custom, time-defined basis.
    • New request trigger enables calling Python plugins via HTTP requests.
    • New in-memory cache for storing data temporarily; cached data can be stored for a single trigger or across all triggers.
    • Integration with virtual environments and install packages. You can now specify a Python virtual environment via the CLI or VIRTUAL_ENV variable and install packages or a requirements.txt.
    • Python plugins are now implemented through triggers only. Simply create a trigger that references your Python plugin code file directly.
    • Snapshots are now persisted in parallel, improving performance by running jobs simultaneously, rather than sequentially.
    • Write to logs from within the Processing Engine.

  • DB and CLI improvements

    • You can now specify the precision on your timestamps for writes using the --precision flag. Includes nano/micro/milli/seconds (ns/us/ms/s).
    • Added a new show system subcommand to display system tables with different options via SQL (default limit: 100)
    • Clearer table creation error messages

Bug fixes

  • If a database was created and the service was killed before any data was written, the database would not be retained.
  • A last cache with specific “value” columns could not be queried.
  • Running CTRL-C no longer stopped an InfluxDB process, due to a Python trigger.
  • A previous build had broken JSON queries for RecordBatches.
  • There was an issue with the distinct cache that caused panics.

Enterprise

Features

  • Cluster management
    • Nodes are now associated with clusters, simplifying compaction, read replication, and rocessing.
    • Node specs are now available for simpler management of cache creations.
  • Mode types
    • Ingest, query, compaction, and processing engine can now all be set individually per node.

InfluxDB 3 Core and Enterprise are now in Beta

InfluxDB 3 Core and Enterprise are now available for beta testing, available under MIT or Apache 2 license.

InfluxDB 3 Core is a high-speed, recent-data engine that collects and processes data in real-time, while persisting it to local disk or object storage. InfluxDB 3 Enterprise is a commercial product that builds on Core’s foundation, adding high availability, read replicas, enhanced security, and data compaction for faster queries. A free tier of InfluxDB 3 Enterprise will also be available for at-home, non-commercial use for hobbyists to get the full historical time series database set of capabilities.
