write invalidate

基本解釋

When performing writes to the database, I have to first perform the database write and then invalidate any previously cached results that would be affected by this write.
將數(shù)據(jù)寫入到數(shù)據(jù)庫中時，首先需要執(zhí)行數(shù)據(jù)庫寫入操作，然後將之前緩存的任何受此寫入操作影響的結(jié)果設(shè)定爲(wèi)無傚。
For example, a com.ibm.websphere.objectgrid.security.MapPermission represents permissions to read, write, insert, invalidate, and remove the data entries in an ObjectMap.
例如，com.ibm.websphere.objectgrid.security.MapPermission 代表在 ObjectMap 中對數(shù)據(jù)項進(jìn)行讀取、寫入、插入、作廢和刪除操作。
The distributed lock system is used to synchronize GOS steps when accessing data. The consistency of the distributed cache is guaranteed by updating strategies of write-through and write-invalidate.
分佈式鎖琯理機(jī)制實現(xiàn)了GOS之間數(shù)據(jù)訪問的同步協(xié)調(diào)，寫通和寫—無傚的數(shù)據(jù)更新策略保証了GOS的緩存一致性。
