SFM

String frequency manager.

Requirement

1. SFM shall process log file in a configurable local folder. Configuration can be done using property sfm.folder property in src/main/resources/application.properties
2. Keep track of how many times a particular string has appeared in those log files. For this I used MapDB
3. Provided an endpoint API to make use of this frequency of String http://localhost:8080/isStringValid?String={string} If the string appears more than 5 times in the last 24 hours, return {"response":"false"}, else return {"response":"true"}

How to run

1. execute run.sh or mvn spring-boot:run

Configuration

folder to be watched

• sfm.folder=./src/test/resources/logs

file name pattern

• sfm.pattern=string-generation-[0-9]+.log

file extension

• sfm.extension=.log

more than below number of occurrences within last 24 hours will make it invalid.

• sfm.wordCount=5
