In order to increase the throughput of your application proportionately with your investment, you need to scale out, add redundancy and process asynchronously. I am not talking about scaling up, which implies adding more fuel to your already sizable database server. As long as you have a single database, there will be latency and you will have to accept it. With extra processing in the form of n actors pounding the cores of your CPU, the database will still be the bottleneck and SPOF. This can buy you some more donuts over and above your current throughput. In an earlier post, I had talked about scaling out the service layer of your application using actors and asynchronous processing. Rather than alternatives, the two technologies are complementary. Hence by writing data directly into Terracotta Network Attached Memory, data can be safely and durable stored, without risk of loss or corruption, and later drained to the DB asynchronously.Ĭan we conclude that for read-only (mostly) usecases, use memcached, while, for read-write usecases, use Terracotta to obtain transparent durability to the persistent store. Terracotta offers a truly coherent and clustered cache that remains consistent even in the presence of database writes through write behind to System of Record.You write into Terracotta Network Attached Memory and the data gets pushed into the database through asynchronous write behinds. In case of Terracotta it is the other way round. How do you handle database updates and prevent staleness of your memcached data ? Updates to data are usually handled by pushing writes to the database and then having some asynchronous processes (or database triggers) build objects that are pushed into memcached.Any algorithm for distribution, HA, failover is the responsibility of the client. Every memcached server is atomic and is not aware of any other memcached server in the cluster. ![]() This is quite a popular misconception that even Dare also mentions in one of his recent posts. Memcached is NOT a distributed hash table.In case you are trying to use it as a data store, think twice and refactor your thoughts. Memcached is a specialized engine for caching *only*.The following is a snapshot directly captured from the Twitter stream. ĭo you think Terracotta is an alternative to Memcached ? Here is a transcript of the chat, with some snippets of my own personal observations and conclusions. Ari was chatty and I thought it would be pretty useful to share his observations with a broader audience. It all started with Ari's initial observation regarding the confusion that exists in people's mind regarding the actual use of memcached and how it compares to Terracotta as a caching solution. Researchers at CSUF seeking literature about film may use other film-related databases, listed here.Last week I was having a chatty tweeter session with Ari Zilka, CTO of Terracotta. In 2022, due to its limited scope, plus other, more comprehensive film literature databases available, the Film Literature Index database was retired. The database was hosted by Indiana University, freely available to the public. In 2001, this print index was converted to a searchable database, covering film literature for the years 1976-2001. The Pollak Library actually has some of these old print indexes (for the years 1973-1977). It pointed researchers to articles about films in hundreds of journals and magazines. The Film Literature Index started in 1973, by the State University of New York, Albany, as a print index of literature about film. What happened to the Film Literature Index database?

The groupings below categorize the library's databases into categories to match your needs. There are many databases useful for CTVA research, but it depends what you need.
