Interesting issues arise in such an architecture, since the time cost of communication between the client and the server is high compared to that of a local memory reference (milliseconds, versus less than 100 nanoseconds): Page shipping versus item shipping The unit of communication for data can be of coarse granularity, such as a page, or ne granularity, such as a tuple (or an object, in the context of object-oriented database systems) We use the term item to refer to both tuples and objects If the unit of communication is a single item, the overhead of message passing is high compared to the amount of data transmitted Instead, when an item is requested, it makes sense also to send back other items that are likely to be used in the near future Fetching items even before they are requested is called prefetching Page shipping can be considered a form of prefetching if multiple items reside on a page, since all the items in the page are shipped when a process desires to access a single item in the page Locking Locks are usually granted by the server for the data items that it ships to the client machines A disadvantage of page shipping is that client machines may be granted locks of too coarse a granularity a lock on a page implicitly locks all items contained in the page Even if the client is not accessing some items in the page, it has implicitly acquired locks on all prefetched items Other client machines that require locks on those items may be blocked unnecessarily Techniques for lock de-escalation, have been proposed where the server can request its clients to transfer back locks on prefetched items If the client machine does not need a prefetched item, it can transfer locks on the item back to the server, and the locks can then be allocated to other clients Data caching Data that are shipped to a client on behalf of a transaction can be cached at the client, even after the transaction completes, if suf cient storage space is available Successive transactions at the same client may be able to make use of the cached data However, cache coherency is an issue: Even if a transaction nds cached data, it must make sure that those data are up to date, since they may have been updated by a different client after they were cached Thus, a message must still be exchanged with the server to check validity of the data, and to acquire a lock on the data Lock caching If the use of data is mostly partitioned among the clients, with clients rarely requesting data that are also requested by other clients, locks can also be cached at the client machine Suppose that a client nds a data item in the cache, and that it also nds the lock required for an access to the data item in the cache Then, the access can proceed without any communication with the server However, the server must keep track of cached locks; if a client requests a lock from the server, the server must call back all con icting locks on the data item from any other client machines that have cached the locks The task becomes more complicated when machine failures are taken into account This technique differs from lock de-escalation in that lock caching takes place across transactions; otherwise, the two techniques are similar. java upc-a Generate UPC-A barcode in Java class using Java UPC-A ...
