Listing all parts in log have no sense. 
Should be either silenced, either combined into a single line.
*        <------> - size
      *
      * If the interval passes through the end of the universe, then cut its right side.
      *
      * Example: SAMPLE 0.4 OFFSET 0.8
      *
      * [----------------****]
      *                  ^ - offset
      *                  <------> - size
      *
      * Next, if the `parallel_replicas_count`, `parallel_replica_offset` settings are set,
      *  then it is necessary to break the received interval into pieces of the number `parallel_replicas_count`,
      *  and select a piece with the number `parallel_replica_offset` (from zero).
      *
      * Example: SAMPLE 0.4 OFFSET 0.3, parallel_replicas_count = 2, parallel_replica_offset = 1
      *
      * [----------****------]
      *        ^ - offset
      *        <------> - size
      *        <--><--> - pieces for different `parallel_replica_offset`, select the second one.
      *
      * It is very important that the intervals for different `parallel_replica_offset` cover the entire range without gaps and overlaps.
      * It is also important that the entire universe can be covered using SAMPLE 0.1 OFFSET 0, ... OFFSET 0.9 and similar decimals.
