zettadb / kunlun

KunlunBase is a distributed relational database management system(RDBMS) with complete NewSQL capabilities and robust transaction ACID guarantees and is compatible with standard SQL. Applications which used PostgreSQL or MySQL can work with KunlunBase as-is without any code change or rebuild because KunlunBase supports both PostgreSQL and MySQL connection protocols and DML SQL grammars. MySQL DBAs can quickly work on a KunlunBase cluster because we use MySQL as storage nodes of KunlunBase. KunlunBase can elastically scale out as needed, and guarantees transaction ACID under error conditions, and KunlunBase fully passes TPC-C, TPC-H and TPC-DS test suites, so it not only support OLTP workloads but also OLAP workloads. Application developers can use KunlunBase to build IT systems that handles terabytes of data, without any effort on their part to implement data sharding, distributed transaction processing, distributed query processing, crash safety, high availability, strong consistency, horizontal scalability. All these powerful features are provided by KunlunBase. KunlunBase supports powerful and user friendly cluster management, monitor and provision features, can be readily used as DBaaS.

Conversion from macaddr8 to macaddr generate wrong result for comparison #478

Open jd-zhang opened 3 years ago

jd-zhang commented 3 years ago

Issue migrated from trac ticket # 106

component: computing nodes | priority: minor

2021-06-16 17:13:02: @jd-zhang created the issue


sql code:

drop table if exists macaddr8_data; CREATE TABLE macaddr8_data (a int, b macaddr8); INSERT INTO macaddr8_data VALUES (1, '08:00:2b:01:02:03'); SELECT b::macaddr <# '08:00:2b:01:02:04' FROM macaddr8_data WHERE a1; SELECT b::macaddr ># '08:00:2b:01:02:04' FROM macaddr8_data WHERE a1; SELECT b::macaddr <> '08:00:2b:01:02:03'::macaddr FROM macaddr8_data WHERE a = 1;

For the above 3 select, kunlun produces: ftt, while official pg produces: tff, opposite values.

Need to check the implementation, and fix it if possible.
