Example 1 with DbConsistencyChecker

use of com.emc.storageos.db.client.impl.DbConsistencyChecker in project coprhd-controller by CoprHD.

the class DBClient method checkDB.

/**
 * This db consistency check is for the whole database and we could detect,
 * 1. The data object record exists but related indices are missing, the scope is the whole db, it will scan all the CFs, from one to
 * next.
 * 2. The index exists but related data object records are missing, the scope is the whole db too, it will scan from one index to next.
 *
 * The indices here means all the indices of each filed of the data object record. If inconsistency found, it will generate several
 * files to do the cleanup work, including rebuilding index.
