Description

Document new 'no archiver' WAL mode activated if WAL Path & WAL Archive Path set to same value.

In this mode all WAL segment files are placed in that folder with absolute index in file name. In that case archiver is not activated.

Configuration example:

DataStorageConfiguration dsCfg = new DataStorageConfiguration();

DataRegionConfiguration regCfg = new DataRegionConfiguration();
regCfg.setPersistenceEnabled(true);
dsCfg.setDefaultDataRegionConfiguration(regCfg);

dsCfg.setWalPath(walAbsPath);
dsCfg.setWalArchivePath(walAbsPath);
