Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)

Test Case: 50k tables, each table contains 10 columns.

Test1: Testing 'explain analyze' to accurately display memory usage.

tidb> desc analyze select * from INFORMATION_SCHEMA.tables;
+----------------+----------+---------+------+---------------+-------------------------------------+---------------+---------+------+
| id             | estRows  | actRows | task | access object | execution info                      | operator info | memory  | disk |
+----------------+----------+---------+------+---------------+-------------------------------------+---------------+---------+------+
| MemTableScan_4 | 10000.00 | 50816   | root | table:TABLES  | time:115.1ms, loops:51, RU:0.000000 |               | 91.3 MB | N/A  |

Test2: Testing mem-quota to successfully cancel SQL queries exceeding the threshold.

tidb> set tidb_mem_quota_query = 80 << 20;
Query OK, 0 rows affected (0.001 sec)

tidb> desc analyze select * from INFORMATION_SCHEMA.tables;
ERROR 8175 (HY000): Your query has been cancelled due to exceeding the allowed memory limit for a single SQL query. Please try narrowing your query scope or increase the tidb_mem_quota_query limit and try again.[conn=463470598]
