rickcrawford / ElasticSearchTest.java
Created July 11, 2012 19:54
I spent a couple hours trying to figure out the client API for ElasticSearch, so I wrote this simple unit test to try out some of the features.
package com.typeahead.dropwizard.elasticsearch;
import static org.elasticsearch.common.xcontent.XContentFactory.jsonBuilder;
import java.util.Date;
import java.util.Map;
import org.elasticsearch.action.admin.cluster.health.ClusterHealthResponse;
import org.elasticsearch.action.admin.cluster.health.ClusterHealthStatus;
import org.elasticsearch.action.admin.cluster.node.info.NodeInfo;

Convert strings with ascii escaped characters to a valid java string. For example \x04 would escape to \n
import org.apache.commons.lang.StringEscapeUtils;
import org.apache.commons.lang.StringUtils;
public class Utils {
public static String decodeHex(String str) {
if (StringUtils.isBlank(str)) {
return str;
}
return StringEscapeUtils.unescapeJava(
str.replaceAll("(?i)\\\\x([0-9a-f]{2})", "\\\\u00$1"))
.trim();

Golang Read from a GCS Cloud Storage bucket

Read data from a public bucket using gzip compression.

First bit of code opens a bucket and lists contents.

Next reads a gzip json file and deserializes it to an array. Please note not very efficient for a large array since the byte array is loaded into memory.

package main

import (
	"compress/gzip"

Create a GCS topic if it doesn't exist, then creates messages

Checks if a topic exists. If it doesn't it will be created. Next it will create messages on that topic with a new subscription.

package main

import (
	"context"
	"log"
	"time"
