Class: ExternalStoreDB - X-Ref
DB accessable external objects.| fetchFromURL( $url ) X-Ref |
| The provided URL is in the form of DB://cluster/id or DB://cluster/id/itemid for concatened storage. |
| batchFetchFromURLs( array $urls ) X-Ref |
| Fetch data from given external store URLs. The provided URLs are in the form of DB://cluster/id or DB://cluster/id/itemid for concatened storage. param: array $urls An array of external store URLs return: array A map from url to stored content. Failed results |
| store( $cluster, $data ) X-Ref |
| getLoadBalancer( $cluster ) X-Ref |
| Get a LoadBalancer for the specified cluster param: string $cluster Cluster name return: LoadBalancer |
| getSlave( $cluster ) X-Ref |
| Get a slave database connection for the specified cluster param: string $cluster Cluster name return: DatabaseBase |
| getMaster( $cluster ) X-Ref |
| Get a master database connection for the specified cluster param: string $cluster Cluster name return: DatabaseBase |
| getTable( $db ) X-Ref |
| Get the 'blobs' table name for this database param: DatabaseBase $db return: string Table name ('blobs' by default) |
| fetchBlob( $cluster, $id, $itemID ) X-Ref |
| Fetch a blob item out of the database; a cache of the last-loaded blob will be kept so that multiple loads out of a multi-item blob can avoid redundant database access and decompression. param: string $cluster param: string $id param: string $itemID return: mixed |
| batchFetchBlobs( $cluster, array $ids ) X-Ref |
| Fetch multiple blob items out of the database param: string $cluster A cluster name valid for use with LBFactory param: array $ids A map from the blob_id's to look for to the requested itemIDs in the blobs return: array A map from the blob_id's requested to their content. |
| mergeBatchResult( array &$ret, array &$ids, $res ) X-Ref |
| Helper function for self::batchFetchBlobs for merging master/slave results param: array &$ret Current self::batchFetchBlobs return value param: array &$ids Map from blob_id to requested itemIDs param: mixed $res DB result from DatabaseBase::select |
| parseURL( $url ) X-Ref |
param: string $url return: array |
