* Introduce multigeneration aggregation * Do not save unused part of RGDatas to disk * Add IO error explanation (strerror) * Reduce memory usage while aggregating * introduce in-memory generations to better memory utilization * Try to limit the qty of buckets at a low limit * Refactor disk aggregation a bit * pass calculated hash into RowAggregation * try to keep some RGData with free space in memory * do not dump more than half of rowgroups to disk if generations are allowed, instead start a new generation * for each thread shift the first processed bucket at each iteration, so the generations start more evenly * Unify temp data location * Explicitly create temp subdirectories whether disk aggregation/join are enabled or not
