# Queries
<a name="metering-and-pricing.queries"></a>

Queries are charged based on the duration of [Timestream compute units (TCUs)](tcu.md) used by your application in TCU-hours as specified on the [Amazon Timestream pricing](https://www.amazonaws.cn/timestream/pricing/) page. Amazon Timestream for LiveAnalytics' query engine prunes irrelevant data while processing a query. Queries with projections and predicates including time ranges, measure names, and/or dimension names enable the query processing engine to prune a significant amount of data and help with lowering query costs.
