如何配置 yugabytedb 进行严格序列化?

How to configure yugabytedb for strict serialization?

从dbmsmusings门户了解到,金融交易需要严格的序列化,不遵守会导致异常。

请指导我配置 yugabytedb 以进行严格序列化,并且它会影响性能 and/or 功能。

YugabyteDB supports snapshot isolationserializable isolation.

1 种方法是在 BEGIN 上设置隔离级别:

yb_demo=# begin transaction isolation level serializable;
BEGIN
yb_demo=# SHOW transaction_isolation;
 transaction_isolation 
-----------------------
 serializable
(1 row)

yb_demo=# commit;
COMMIT
yb_demo=# SHOW transaction_isolation;
 transaction_isolation 
-----------------------
 read committed
(1 row)

另一种方法是使用 SET TRANSACTION 语句:

yb_demo=# begin;
BEGIN
yb_demo=# SHOW transaction_isolation;
 transaction_isolation 
-----------------------
 read committed
(1 row)

yb_demo=# SET TRANSACTION ISOLATION LEVEL serializable;
SET
yb_demo=# SHOW transaction_isolation;
 transaction_isolation 
-----------------------
 serializable
(1 row)

yb_demo=# commit;
COMMIT
