# General FAQ for Amazon Timestream for InfluxDB 3
<a name="faq-general"></a>

Common questions about Amazon Timestream for InfluxDB 3, its architecture, editions, and regional availability. For a full overview, see [What is Timestream for InfluxDB 3?](influxdb3.md#what-is-timestream-for-influxdb-3).

**What is Amazon Timestream for InfluxDB 3?**  
Amazon Timestream for InfluxDB 3 is a managed time-series database service that runs InfluxDB 3 on AWS. It is designed for large-scale time-series analytics using open-source APIs. The service handles provisioning, patching, backups, and software updates so you can focus on your applications.

**How is InfluxDB 3 different from InfluxDB v2?**  
InfluxDB 3 is a complete architectural redesign. It replaces the TSM (Time-Structured Merge tree) storage engine with Apache Arrow for in-memory processing, Apache DataFusion for query execution, and Apache Parquet for columnar storage on Amazon S3. This enables better performance for high-cardinality data and more efficient scaling for analytical workloads.

**What is the difference between Core and Enterprise editions?**  
Core is a cost-effective, single-node edition optimized for real-time monitoring of recent data, typically around 3 days. It does not include compaction or multi-node deployments, which means query performance degrades as data ages. Core is best suited for dashboards, real-time alerting, and development or proof-of-concept workloads.  
Enterprise is designed for production workloads that require high availability and long-term data retention. Key differences include:  
+ **Compaction** – Enterprise includes compaction capabilities that maintain query performance over time by optimizing Parquet file organization. Without compaction, Core accumulates small files that slow down queries on older data.
+ **Multi-node clusters** – Enterprise supports multi-node deployments across multiple Availability Zones with dedicated ingest, query, and compactor nodes. Core is limited to a single node.
+ **Read replicas** – Enterprise supports query-only nodes to scale read-heavy workloads independently from ingest.
+ **Historical queries** – Enterprise includes single series indexing for optimized long-term data analysis, making it suitable for months or years of data retention.
Choose Core for near real-time monitoring where cost is a priority. Choose Enterprise when you need high availability, compaction, or long-term data analysis.
