in module ETS by letting several processes work in the same table at the same time. 1.3 Scope In this thesis project, there are three parts of tests being included: The first part is testing the main functions in Module ETS. This module is an interface to the Erlang built-in term storage BIFs [6].

Notice that type ordered_set in Ets is not yet provided by Dets, neither is the limited support for concurrent updates that makes a sequence of first and next calls safe to use on fixed ETS tables. Both these features may be provided by Dets in a future release of Erlang/OTP.

Contribute to liuweiccy/ets_cache development by creating an account on GitHub. Erlang uses a built-in database called ets (Erlang Term Storage) for some processes that require fast access from memory in constant access time (rather than logarithmic access time). The maximum number of tables can be set using the erlang.max_ets_tables setting. I fancy the Erlang / Elixir way of creating separate actors for tasks and let them fail if they misbehave and all the corresponding OTP theory. Putting the direct ETS access into this context, I feel like ETS is a hack.

The actual limit can be slightly higher than the one specified, but never lower. The scalability of ETS tables of type ordered_set with the write_concurrency option is substantially better in Erlang/OTP 22 than earlier releases. In some extreme cases, you can expect more than 100 times better throughput in Erlang/OTP 22 compared to Erlang/OTP 21. The cause of this improvement is a new data structure called the contention adapting search tree (CA tree for short).
