The viability of implementing an in-memory database, Erlang ETS, using a relatively-new data structure, called a Judy array, was studied by comparing the

The keypos is the 1-based index in the tuple to be stored that will be used as the key for the entry. If you remember from the part 3 of the introduction to ETS Erlang Term Storage (ETS), a library which provides a key-value store in-memory database that is implemented in C for efﬁciency. In many Erlang applications, ETS is heavily used and is a critical component of their implementation.

Notice that there is no 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). This blog The same oddity applies to all kinds of table iterations; ets:next/1, ets:select/1-3, ets:match/1-3 and friends. They may all miss concurrently inserted keys and return a key that has never existed in the table ordered directly after the previously returned key. 2017-05-19 · ETS, or Erlang Term Storage, is one of those innovative Erlang features that feels like it has been hiding in plain sight once you use it.

erlang:memory/1: erlang:memory(ets) returns the memory size, in bytes, allocated to ETS. ets:i/0 : an overview of all active ETS tables (a bit like viewing system tables in TV , but with type and memory data).

An ets table is deleted as soon as its owning process dies. The erlang shell dies whenver it receives an exception and is silently restarted.

The erlang shell dies whenver it receives an exception and is silently restarted. So, when you get the first exception, the current shell process dies causing the ets table to be deleted, and then a new shell process is started for you. Now, when you try another ets:match, it fails because the table no longer exists.

After digging in the source of ets.erl, found out, that foldl/3 uses the same approach (fixing the table with safe_fixtable/2, starting with first/1, and recursively calling next/2), so it would ensure reaching each element only once, but for my scenario, I can do the same, without the overhead of accumulators, since I do not need them. The number of tables stored at one Erlang node is limited. The current default limit is approximately 1400 tables. The upper limit can be increased by setting the environment variable ERL_MAX_ETS_TABLES before starting the Erlang runtime system (i.e. with the -env option to erl / werl).
