Hi, all:
In the new cluster version, we will change the syntax for NULL as follows:
NULL Filter: IS NULL / IS NOT NULL
NULL Operation:
1.comparison operators: the result is NULL if you use arithmetic comparison
operators such as ‘=‘, ‘<‘ or ‘>=‘ to NULL.
2.logic operators: you can treat NULL
Qingxin's chart shows the performance difference clearly.
In most case,insertTablet > insertRecords > insertRecord > JDBC.
