OceanBase最大支持几个副本？

那么oceanbase最大支持几个副本集呢？ 测试一下便知：

obclient> CREATE TABLE t1_2k (
->   "OWNER" VARCHAR2(128) DEFAULT NULL NOT NULL,
->   "OBJECT_NAME" VARCHAR2(128),
-> ) COMPRESS FOR ARCHIVE REPLICA_NUM = 6 BLOCK_SIZE = 2048 USE_BLOOM_FILTER = FALSE TABLET_SIZE = 8388608 PCTFREE = 10;
Query OK, 0 rows affected (0.04 sec)
obclient> drop table t1_2k;
Query OK, 0 rows affected (0.01 sec)
obclient> CREATE TABLE t1_2k (
->   "OWNER" VARCHAR2(128) DEFAULT NULL NOT NULL,
->   "OBJECT_NAME" VARCHAR2(128),
-> ) COMPRESS FOR ARCHIVE REPLICA_NUM = 7 BLOCK_SIZE = 2048 USE_BLOOM_FILTER = FALSE TABLET_SIZE = 8388608 PCTFREE = 10;
ERROR-00600: internal error code, arguments: -4007, Not supported feature or function
obclient>

可见目前最大支持6个副本集。
