|
## Description
|
|
This statement is used to show the amount of data and the number of replica
|
|
Grammar:
|
|
SHOW DATA [FROM db_name[.table_name]];
|

Explain:
|
|
1. If you do not specify the FROM clause, use the amount of data and the number of replica that shows the current DB subdivided into tables
|
|
2. If the FROM clause is specified, the amount of data and the number of replica subdivided into indices under the table is shown.
|
|
3. If you want to see the size of individual Partitions, see help show partitions
|
|
|
|
## example
|
|
1. Display the data volume, replica size, aggregate data volume and aggregate replica count of each table of default DB
|
|
SHOW DATA;
|
|
|
