batch-processing

A helpful FAQ from Stata describes that arguments can be passed to do files. My do file looks like this: * program.do : Program to fetch information from main dataset args inname outname save `outname', emptyok // file to hold results insheet using `inname', comma clear names case // a bunch of processing save `outname', replace According to the FAQ, this script can be run using do filename.csv result.dta . When I run this command from within Stata, everything works fine. The program is long, however, so I want to run it in batch mode. Stata has another FAQ about batch mode. Combining the

I'm trying to pass an object between batchlets, but I've encountered a problem when trying to access the jobContext from a partitioned step (batchlet). According to the JSR 352 Specification 9.4.1.1 Batch Context Lifecycle and Scope: A batch context has thread affinity and is visible only to the batch artifacts executing on that particular thread. A batch context injected field may be null when out of scope. Each context type has a distinct scope and lifecycle as follows: 1. JobContext There is one JobContext per job execution. It exists for the life of a job. There is a distinct JobContext

What do you mean by Batch Statements are atomic in cassandra? Docs are a bit confusing in nature to be precise. Does it mean that queries are atomic across nodes in cluster? Say,for example, i have a batch with 100 queries. If the 40th query in batch fails, what happens to the 39 queries executed in the batch? I understand that there is a batchlog created under the hood and it will take care of the consistency for partial batches. Does it remove the rest of the 39 entries and provide the required atomic nature of batch queries. In MYSQL, we set autocommit to false and hence we can rollback.

What I want to do is following. I want to create some bat file, that will recursively search for files starting from current directory and replace with the file that I provided. For ex. if I want to search and replace test1.txt, I'm opening this mini app and writing text1.txt, and placing the file that I want to be replaced with. Dir app.bat test1.txt // app will recursively search inside folder 1 and folder 2 and will replace all found results with test1.txt folder 1 folder 2 I wonder, if there is ready to go app or bat file for this reason? The Batch file below start from current directory,

The aim was to create a database of TfRecords. Given: I have 23 folders each contain 7500 image, and 23 text file, each with 7500 line describing features for the 7500 images in separate folders. I created the database through this code: import tensorflow as tf import numpy as np from PIL import Image def _Float_feature(value): return tf.train.Feature(float_list=tf.train.FloatList(value=[value])) def _bytes_feature(value): return tf.train.Feature(bytes_list=tf.train.BytesList(value=[value])) def _int64_feature(value): return tf.train.Feature(int64_list=tf.train.Int64List(value=[value])) def

I have hundreds of files where I need to change a portion of its text. For example, I want to replace every instance of "http://" with "rtmp://" . The files have the .txt extention and are spread across several folders and subfolder. I basically am looking for a way/script that goes trough every single folder/subfolder and every single file and if it finds inside that file the occurrence of "http" to replace it with "rtmp". You can do this with a combination of find and sed : find . -type f -name \*.txt -exec sed -i.bak 's|http://|rtmp://|g' {} + This will create backups of each file. I

What is the best practice for this problem? Is there any batching features built-in? Sample code: using (ITransaction transaction = _session.BeginTransaction()) { _session.Delete("FROM myObject o WHERE o.Id = IN(1,2,...99999)"); transaction.Commit(); } Thanks in advance. HQL supports the IN clause, and if you use setParameterList you can even pass in a collection. var idList = new List<int>() { 5,3,6,7 }; _session.CreateQuery("DELETE MyDataClass o WHERE o.Id IN (:idList)") .SetParameterList("idList", idList) .ExecuteUpdate(); Be aware, like mentioned by ddango in a comment, that relationship
