I want to create a table in ets if it does not exists . How can I check if this named exists or not ?

I did some tests around performance of selection from ets tables and noted weird behaviour. For example we have a simple ets table (without any specific options) which stores key/value - a random s...

I am using ets() and auto.arima() functions from forecast package to predict future values in R. Which criteria should be used to choose the best model between these two? Following is the accurac...

Suppose I have an ets table like: I = ets:new(mytable, [named_table, set]). ets:insert(I, {10,{10, 4 ,"description"}). I would like to update the element 4 using the ets:update_counter. I tried...

I'm using ets via elixir as a simple in-memory persistence layer to store and retrieve keys and also for the occasional foldl which involves reducing many duplicate keys that have different values....

I find "The functions ets:select/2 and mnesia:select/3 should be preferred over ets:match/2,ets:match_object/2, and mnesia:match_object/3" form ref link : http://www.erlang.org/doc/efficiency_guide...

I'm considering using Erlang's ETS as a cache for user searches in a new Elixir project. Based on user input, the system will do lookups using an expensive third-party API. In order to avoid makin...

I have a lot of analytics data which I'm looking to aggregate every so often (let's say one minute.) The data is being sent to a process which stores it in an ETS table, and every so often a timer ...

ets:select vs mnesia:select Which is better to use.And also in case of insertion and deletion which one of these two we should use.I am working on ejabberd.Any pointers?

Give an ETS table with data, the info/1 function returns various properties for the table, including a size value which is specific to the number of rows rather than the physical size. Is there a...

I create ETS table in one process and I want use it in another process. How I "open" ETS table in second process? Could not find good function in man pages.

I need some suggestion for the erlang in-memory cache system. The cache item is key-value based storage. key is usually an ASCII string; value is erlang's types include number / list / tupl...

I have heard that specifying records through tuples in the code is a bad practice: I should always use record fields (#record_name{record_field = something}) instead of plain tuples {record_name, v...

I'm coming into an existing (game) project whose server component is written entirely in erlang. At times, it can be excruciating to get a piece of data from this system (I'm interested in how many...

I have qlc RefsBlocked = qlc:e(qlc:q([ Ref1 || {{Ref1, {pattern, {_Status1, _Pattern1, Limit1}}}, Count} <- dict:to_list( qlc:fold( fun({Key, _Ref2}, Acc) -> dict:update_counter(Key, 1,...

((Please forgive me that I ask more than one question in a single thread. I think they are related.)) Hello, I wanted to know, what best practices exist in Erlang in regards to per-module precompi...

Short version: is it safe to use ets:foldl to delete every ETS record as one is iterating through them? Suppose an ETS table is accumulating information and now it's time to process it all. A reco...

I'm building an erlang server. Users sends http requests to the server to update their status. The http request process on the server saves the user status message in memory. Every minute the serve...

I've been learning how to use ets, but one thing that has bothered me is that, occasionally*, ets:match throws a bad argument… And, from them on, all subsequent calls (even calls which previously w...
