storage

I'm using PostgreSQL 9.2 on Oracle Linux Server release 6.3. According to the storage layout documentation , a page layout holds: PageHeaderData(24 byte) n number of points to item(index item / table item) AKA ItemIdData(4 byte) free space n number of items special space I tested it to make some formula to estimate table size anticipated...(TOAST concept might be ignored.) postgres=# \d t1; Table "public.t1" Column ',' Type ',' Modifiers ---------------+------------------------+------------------------------ code |character varying(8) |not null name |character varying(100) |not null act_yn

I have many many .RData files containing one dataframe that I had saved in a previous analysis and the data frame has the same name for each file loaded. So for example using load(file1.RData) I get a data frame called 'df', then using load(file2.RData) I get a data frame with the same name 'df'. I was wondering if it is at all possible to combine all these .RData files into one big .RData file since I need to load them all at once, with the name of each df equal to the file name so I can then use the different data frames. I can do this using the code below, but it is very intricate, there

I see in the docs how do do this for pods, but I want to use a replication controller to manage my pods, ensuring that there is always one up at all times. How can I define a replication controller where the pod being run has a persistent volume? How is this related to Kubernetes persistentVolumes and persistentVolumeClaims? Mark Turansky Using a persistent volume in a Replication Controller works great for shared storage. You include a persistentVolumeClaim in the RC's pod template. Each pod will use the same claim, which means it's shared storage. This also works for read-only access in

I have a list in my program. I have a function to append to the list, unfortunately when you close the program the thing you added goes away and the list goes back to the beginning. Is there any way that I can store the data so the user can re-open the program and the list is at its full. GLHF You can make a database and save them, the only way is this. A database with SQLITE or a .txt file. For example: with open("mylist.txt","w") as f: #in write mode f.write("{}".format(mylist)) Your list goes into the format() function. It'll make a .txt file named mylist and will save your list data into

So, one of my tables in MySQL which uses the InnoDB storage engine will contain multi-billion rows(with potentially no limit to how many will be inserted). Can you tell me what sort of optimizations i can do to help speed up things? Cause with a few million rows already, it will start getting slow. Of course if you suggest to use something else. The only options i have are PostgreSQL and Sqlite3. But I've been told that sqlite3 is not a good choice for that. As for postgresql, i have absolutely no idea how it is, as i've never used it. I imagine though, at least about 1000-1500 inserts per

I want to make Cookbook application for storing and reading (and updating) recipes, or anything else to practice OOP programming and thinking. But, I am not sure, what way of storing data, in this case, recipes, is the best in c# (Visual Studio Express). I want to optimize saving and loading data in program, but I have no experience. What is the best way? Is it through XML, SQL, or just plain TXT? Or some other way? Harrison I would suggest using a localDB in SqlExpress.
