一.从缓存中看看是否我们已经有该Region的getCachedLocation()方法 首先我们看下从缓存中看看是否我们已经有该Region的getCachedLocation()方法,代码如下: /** * Search the cache for a location that fits our table and row key. * Return null if no suitable region is located. * @return Null or region...
// 如果我们支持在缓存中查找,先在缓存中看看是否我们已经有该Region if (useCache) { RegionLocations locations = getCachedLocation(tableName, row); if (locations != null && locations.getRegionLocation(replicaId) != null) { return locations; } } // build the key of the meta region we should...
