This system table contains all profiling information of the running queries of current user. For more information on profiling, see Profiling. All users have access to the table.
Column Name | Description |
---|---|
SESSION_ID | ID of the session |
STMT_ID | Serially numbered ID of statement within a session |
COMMAND_NAME |
Name of the statement (for example, SELECT , COMMIT , or
MERGE )
|
COMMAND_CLASS |
Class of statement (for example, DQL , TRANSACTION ,
or DML )
|
PART_ID | Serially numbered ID of the execution part within the statement |
PART_NAME | Name of the execution part (see also Profiling) |
PART_INFO |
Extended information of the execution part. For example:
|
PART_FINISHED | Defines whether the execution part has already finished |
OBJECT_SCHEMA | Schema of the processed object |
OBJECT_NAME | Name of the processed object |
OBJECT_ROWS | Number of rows of the processed object |
OUT_ROWS | Number of result rows of the execution part |
DURATION | Duration of the execution part in seconds |
CPU | CPU utilization in percentage of the execution part (averaged over the duration) |
TEMP_DB_RAM_PEAK | Usage of temporary DB memory of the execution part in MiB (overall nodes, maximum over the duration) |
PERSISTENT_DB_RAM_PEAK | Usage of modified, persistent DB memory of the execution part in MiB (overall nodes, maximum over the duration) |
HDD_READ |
Hard disk maximum read ratio in MiB per second (per node, averaged over the duration)
If this value is larger than 0, then data had to be loaded into the main memory. |
HDD_WRITE |
Hard disk maximum write ratio in MiB per second (per node, averaged over the duration)
This column reflects only the data
written during a |

CACHE_WRITE_SIZE | Total size of data written to cache in MiB (sum over all nodes) |
CACHE_WRITE_DURATION | Time spent writing data to cache in seconds (maximum over all nodes) |
REMOTE_READ_SIZE | Total size of data read from remote storage in MiB (sum over all nodes) |
