GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox Ĭonfirm that you can login to database as netbox user.

$ sudo -u postgres psqlĬREATE USER netbox WITH PASSWORD ' StrongPassword' Then Create a database and user for NetBox.

So install and configure it on Ubuntu 18.04 using our previous guide below: NetBox uses PostgreSQL database server to store its data. Sudo apt-get install -y git gcc nginx redis supervisor python3 python3-dev python3-pip python3-setuptools build-essential libxml2-dev libxslt1-dev libffi-dev graphviz libpq-dev libssl-dev zlib1g-dev Step 2: Install and configure PostgreSQL database server Start by installing all dependency applications required to run NetBox on Ubuntu 18.04 LTS.

Follow them in order of the appearance, though you can skip a part if you have the software being installed already configiured. This section will discuss the actual steps you need to follow to have NetBox installed on your Ubuntu 18.04 LTS server. Install NetBox on CentOS 7 with Apache and Supervisord Install NetBox on Ubuntu 18.04 LTS.Assuming you are using Java 8 or later, the Stream API can be very helpful. This will require changing the method signature to use a return type other than List. This means that each line of the file is processed and then passed directly to the output, without collecting all of the lines in memory in between. Otherwise, the best way to deal with large amounts of data in a bounded amount of memory is to use a streaming approach. If you have enough memory available on the machine to assign a heap size large enough to hold the entire contents, that will be the simplest solution, as it won't require changing the code. Each line may not consume much memory, but multiplied by millions of lines, it all adds up. The memory consumption would be less from the replace and split operations, and more from the fact that the entire contents of the file need to be read into memory in this approach. The main problem is using too much heap memory, and the performance problem is likely to be due to excessive garbage collection when the remaining available heap is very small (but it's best to measure and profile to determine the exact cause of performance problems). I don't think that splitting this work onto multiple threads is going to provide much improvement, and may in fact make the problem worse by consuming even more memory. Do you know of a different approach to split at comas and replace the double quotes in each CSV line ? Would StringBuilder be of any healp here ? What about StringTokenizer ? How could I reduce the amount of heap memory used in the process ? Is the multithread implementation with Callable correct ? How could I improve the speed of the CSV reading ? Other than that the api is running out of heap memory when running on the server, I know that a solution would be to enhance the amount of available memory but I suspect that the replace() and split() operations on strings made in the Callable(s) are responsible for consuming a large amout of heap memory.

To improve speed processing, I tried to implement multithreading with Callable(s) but I am not familiar with that kind of concept, so the implementation might be wrong.

The code works fine on my local machine but it is very slow : it takes about 20 seconds to process 450 columns and 40 000 lines. I am not guaranteed to have the same header between files (each file can have a completly different header than another), so I have no way to create a dedicated class which would provide mapping with the CSV headers.Ĭurrently the api controller is calling a csv service which reads the CSV data using a BufferReader. It has to read big CSV files which will contain more than 500 columns and 2.5 millions lines each. I am currently working on a spring based API which has to transform csv data and to expose them as json.
