Fast import data to mysql in Java -

-

how long take insert 500.000 records csv file mysql database java code? database hosted on localhost.

table structure: ai id, | varchar(8) | datetime | int | varchar(2). code need insert 70.000 records on 40 minutes. there way faster? here main part of code:

csvreader pro  ducts = new csvreader(path); products.readheaders(); stmt = con.createstatement(); string updatestring = "insert table (t_v1, date, t_v2, t_v3) values (?,?,?,?)"; preparedstatement preparedstatement = con.preparestatement(updatestring);              while (products.readrecord()) {                 v1= products.get("v1");                 date = format.parse(products.get("date") + " " + products.get("hour"));                 java.sql.date datedb = new java.sql.date(data.gettime());                 v2 = products.get("v2");                 v3 = products.get("v3");                    preparedstatement.setstring(1, v1);                 preparedstatement.setdate(2,datedb);                 preparedstatement.setint(3, integer.parseint(v2));                 preparedstatement.setstring(4, v3);                    preparedstatement.executeupdate();             }

according advice moved creation of statement out of loop. have 33 records per second, after had 29 rps.

i might opt using load data statement mysql instead of using java:

load data local infile '/path/to/your/file.csv' table table;

this avoid lot of overhead have, assuming processing each line before inserting mysql.

you can execute load data statement java using raw jdbc.

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
