----------------------------------
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.
