> Key: IOTDB-3727
> URL: https://issues.apache.org/jira/browse/IOTDB-3727
> Project: Apache IoTDB
> Issue Type: Task
> Reporter: Minghui Liu
> Priority: Minor
> Labels: pull-request-available
> Fix For: 0.14.0-SNAPSHOT
>
>
> We should support clear cache in 0.14.
>
> *Function definition:*
> Clear the cache of chunk, chunk metadata, timeseries metadata and bloom
> filter to release the memory footprint.
> In cluster mode, we must consider the distinction between requests to clear
> the cache of a single node or the entire cluster.
> The syntax definition might look like this:
> CLEAR CACHE (ON (LOCAL | CLUSTER))?
