Shouldn't Max_data_length on a heap table be the same as the
max_heap_table_size variable as long is max_rows is not set? My heap table can
grow up to about 200mb. If I set the limit max_heap_table_size at 256MB,
Max_data_length ends up being around 110MB. This gives me the 'table is full'
error when it grows over (about) 110MB. I had to set it at 512MB to get it
at it's current value. Is this a bug or am I missing something?
show table status:
Name | Type | Row_format | Rows | Avg_row_length | Data_length |
Max_data_length
mydata | HEAP | Dynamic | 0 | 187 | 0 |
237901961
show variables:
Variable_name | Value
max_heap_table_size | 536869888
