Can writeSynchronizationMode be modified online?

[gunman524 <gu...@126.com>]

Hi there,

A simple question, can writeSynchronizationMode be modified online?  As my
cache currently in 'full_sync" mode, can it be modified to 'primary_sync'
online?  like by restful or  visor?

BTW, the cache I created by DDL
CREATE TABLE IF NOT EXISTS person ( id int,orgId LONG, name VARCHAR, salary
LONG ,PRIMARY KEY (id) ) WITH "TEMPLATE=PARTITIONED,backups=1,
affinityKey=id, value_type=MyPerson"

why writeSynchronizationMode  be set as full_sync? I think the default value
is "primary_sync".

Hello,

Write synchronization mode is one of the crucial settings of cache
configuration and cannot be changed after a cache has been created.
By default, SQL engine uses FULL_SYNC synchronization mode [1]
You can choose the required mode by specifying the additional parameter as
follows:
CREATE TABLE IF NOT EXISTS person ( id int,orgId LONG, name VARCHAR, salary 
LONG ,PRIMARY KEY (id) ) WITH "TEMPLATE=PARTITIONED,backups=1, 
affinityKey=id, value_type=MyPerson,WRITE_SYNCHRONIZATION_MODE=PRIMARY_SYNC"

Thanks!
