当然,从上游讯息和将来趋势上看,MySQL 5.7 版本的生命周期曾经靠近序幕(存量市场是否会被疾速迭代有待察看,不过增量市场势必会用新、用好、用低成本、用高效能),所以,StoneDB 团队在过来的一年里除了踊跃做 5.7 版本的存量市场,咱们其实很早就开始布局了 8.0 的版本布局,在往年的 6 月初,咱们就顺利地公布了 StoneDB-8.0-V1.0.1 版本,后续的研发重点也会逐步以 8.0 为主代替 5.7 的骨干开发地位,同步上游,继续加强 AP 能力,趁势而行,满足更多的增量市场需求。以下,是本次版本的公布日志:
Release Notes for StoneDB-5.7-V1.0.4-alpha
稳定性
- 修复在导入数据时候,增量数据导致的 crash(「#1805」)
- 修复在 union all 字句后果集导致的 crash(「#1875」)
- 修复在大数据量状况下应用聚合函数导致的 crash(「#1855」)
- 修复主从复制下的内存溢出导致的 crash(「#1549」)
新个性
2.1 反对 insert/update ignore 语法个性
当更新 Tianmu 时候,对于主键抵触的记录将被跳过,而后执行后续的更新操作。例如:
CREATE TABLE t1 (id int(11) NOT NULL auto_increment,parent_id int(11) DEFAULT '0' NOT NULL,level tinyint(4)
DEFAULT '0' NOT NULL, PRIMARY KEY (id)) engine=tianmu;
INSERT INTO t1 VALUES (3,1,1),(4,1,1);
执行 update ignore t1 set id=id+1;
语句会疏忽 PK=3 的更新,因为更新后的主键会与 PK=4 抵触。继续执行 PK=4 的更新,更新后 PK=5。
mysql> CREATE TABLE t1 (id int(11) NOT NULL auto_increment, parent_id int(11) DEFAULT '0' NOT NULL, level tinyint(4)
-> DEFAULT '0' NOT NULL, PRIMARY KEY (id)) engine=tianmu;
Query OK, 0 rows affected (0.01 sec)
mysql> INSERT INTO t1 VALUES (3,1,1),(4,1,1);
Query OK, 2 rows affected (0.01 sec)
Records: 2 Duplicates: 0 Warnings: 0
mysql> update t1 set id=id+1;
ERROR 1062 (23000): Duplicate entry '4' for key 'PRIMARY'
mysql> select * from t1;
+----+-----------+-------+
| id | parent_id | level |
+----+-----------+-------+
| 3 | 1 | 1 |
| 4 | 1 | 1 |
+----+-----------+-------+
2 rows in set (0.00 sec)
mysql> update ignore t1 set id=id+1;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 2 Changed: 2 Warnings: 0
mysql> select * from t1;
+----+-----------+-------+
| id | parent_id | level |
+----+-----------+-------+
| 3 | 1 | 1 |
| 5 | 1 | 1 |
+----+-----------+-------+
2 rows in set (0.00 sec)
2.2 ROW 格局反对 Load 语句转换为 write row
当 StoneDB 作为主机时候,Load 语句将以 insert into 的形式被写进 binlog。

2.3 反对 AggregatorGroupConcat 函数
mysql> select GROUP_CONCAT(t.id) from sequence t;
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| GROUP_CONCAT(t.id) |
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| 3000000000010000,3000000000010001,3000000000010002,3000000000010003,3000000000010004,3000000000010005,3000000000010006,3000000000010007,3000000000010008,3000000000010009,3000000000010010 |
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.01 sec)
2.4 反对 uion/union all 中应用 select 111 或者 select 111 from dual 场景
mysql> select id from tt union all select 2222 c1 from dual;
+------+
| id |
+------+
| 1111 |
| 2222 |
+------+
mysql> select id from tt union all select 2222 ;
+------+
| id |
+------+
| 1111 |
| 2222 |
+------+
-- PS:select 111(from dual) 呈现地位非第一子句地位
