[jira] [Created] (IOTDB-2065) TsFileSequenceReader will be cached for 100s even no longer used

Jialin Qiao created IOTDB-2065:
----------------------------------

             Summary: TsFileSequenceReader will be cached for 100s even no longer used
                 Key: IOTDB-2065
                 URL: https://issues.apache.org/jira/browse/IOTDB-2065
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Jialin Qiao


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.
