Package org.apache.iotdb.session.pool

Class SessionPool

  • public class SessionPool
extends java.lang.Object
    SessionPool is a wrapper of a Session Set. Using SessionPool, the user do not need to consider how to reuse a session connection. Even if the session is disconnected, the session pool can recognize it and remove the broken session connection and create a new one.

    If there is no available connections and the pool reaches its max size, the all methods will hang until there is a available connection.

    If a user has waited for a session for more than 60 seconds, a warn log will be printed.

    The only thing you have to remember is that:

    For a query, if you have get all data, i.e., SessionDataSetWrapper.hasNext() == false, it is ok. Otherwise, i.e., you want to stop the query before you get all data (SessionDataSetWrapper.hasNext() == true), then you have to call closeResultSet(SessionDataSetWrapper wrapper) manually. Otherwise the connection is occupied by the query.

    Another case that you have to manually call closeResultSet() is that when there is exception when you call SessionDataSetWrapper.hasNext() or next()

        Compatible for rel/0.12, this method will create an unaligned flat template as a result. Notice that there is no aligned concept in 0.12, so only the first measurement in each nested list matters.
        Parameters:
        name - name of the template
        schemaNames - it works as a virtual layer inside template in 0.12, and makes no difference after 0.13
        measurements - the first measurement in each nested list will constitute the final flat template
        dataTypes - the data type of each measurement, only the first one in each nested list matters as above
        encodings - the encoding of each measurement, only the first one in each nested list matters as above
        compressors - the compressor of each measurement
