> Key: IOTDB-2065
> URL: https://issues.apache.org/jira/browse/IOTDB-2065
> Project: Apache IoTDB
> Issue Type: Bug
> Reporter: Jialin Qiao
> Assignee: Alima777
> Priority: Major
> Labels: pull-request-available
>
> In FileReaderManager, we cached all opened TsFileSequenceReader and maintain
> an usage count for each reader.
> We register a timed thread (cacheFileReaderClearPeriod=100s) to check if a
> reader is no longer used.
> We could check and release the reader when we decrease its usage count in
> endQuery.
