    • getExecutorPoolSize

      public int getExecutorPoolSize()
      Gets the number of threads responsible for execution of SQL statements.
      Returns:
      number of threads responsible for execution of SQL statements
    • setExecutorPoolSize

      public SqlConfig setExecutorPoolSize​(int executorPoolSize)
      Sets the number of threads responsible for execution of SQL statements.

      The default value -1 sets the pool size equal to the number of CPU cores, and should be good enough for most workloads.

      Setting the value to less than the number of CPU cores will limit the degree of parallelism of the SQL subsystem. This may be beneficial if you would like to prioritize other CPU-intensive workloads on the same machine.

      It is not recommended to set the value of this parameter higher than the number of CPU cores because it may decrease the system's overall performance due to excessive context switches.

      Defaults to -1.

      Parameters:
      executorPoolSize - number of threads responsible for execution of SQL statements
      Returns:
      this instance for chaining
    • getStatementTimeoutMillis

      public long getStatementTimeoutMillis()
      Gets the timeout in milliseconds that is applied to statements without an explicit timeout.
      Returns:
      timeout in milliseconds
    • setStatementTimeoutMillis

      public SqlConfig setStatementTimeoutMillis​(long statementTimeoutMillis)
      Sets the timeout in milliseconds that is applied to statements without an explicit timeout.

      It is possible to set a timeout through the SqlStatement.setTimeoutMillis(long) method. If the statement timeout is not set, then the value of this parameter will be used.

      Zero value means no timeout. Negative values are prohibited.

      Defaults to DEFAULT_STATEMENT_TIMEOUT_MILLIS.

      Parameters:
      statementTimeoutMillis - timeout in milliseconds
      Returns:
      this instance for chaining
