Question

让我们尝试使用例如时间戳作为主键创建表：

0: jdbc:ignite:thin://127.0.0.1/> create table t3 (i date primary key, i2 int);
Error: class org.apache.ignite.IgniteCheckedException: Failed to find value class in the node classpath (use default marshaller to enable binary objects) : SQL_PUBLIC_T3_203867a5_800b_4821_9690_e8902ca7b8e1 (state=50000,code=0)
java.sql.SQLException: class org.apache.ignite.IgniteCheckedException: Failed to find value class in the node classpath (use default marshaller to enable binary objects) : SQL_PUBLIC_T3_203867a5_800b_4821_9690_e8902ca7b8e1

    at sqlline.SqlLine.start(SqlLine.java:373)
    at sqlline.SqlLine.main(SqlLine.java:265)

如上所示，没关系。现在让我们尝试创建以日期为主键的表：

此外，我在日志中收到此错误：https://pastebin.com/wLYiF0x0

我想它很快就会修复 - https://issues.apache.org/jira/browse/IGNITE-8552

如果将键和值类型添加到ddl命令，则它可以工作：

create table t2(i timestamp primary key, i2 date
) WITH "key_type=KeyType, value_type=ValueType";

Ignite failes以创建以日期为主键的表
