We widely use Kaizen in-house, recommend to our partners
and continuously improve it every week.


  • Both http and https protocols
  • Both fully qualified and self-signed TLS certificates
  • SSH tunnels e.g. ssh:// as Proxy and as Host
  • HTTP proxies e.g. as Proxy and as Host
  • Parallel connections
  • Basic HTTP authentication

HTTPS termination example by Nginx:

# elasticsearch.conf
upstream elasticsearch {
  keepalive 15;
server {
  listen 443 ssl default_server;
  ssl_certificate /etc/nginx/elasticsearch.crt;
  ssl_certificate_key /etc/nginx/elasticsearch.key;
  client_max_body_size 100m;
  location / {
    proxy_pass http://elasticsearch;
    proxy_http_version 1.1;
    proxy_set_header Connection "Keep-Alive";
    proxy_set_header Proxy-Connection "Keep-Alive";

$ sudo openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/nginx/elasticsearch.key -out /etc/nginx/elasticsearch.crt
$ sudo nginx reload

Basic authentication example by Nginx:

# elasticsearch.conf
server {
  listen 8080 default_server;
  location / {
    auth_basic "Restricted";
    # user:$apr1$lf6n8xgu$PtNgutz9WHROz08RNIfy21
    # user:password
    auth_basic_user_file /etc/nginx/.htpasswd;

$ sudo nginx reload

Indices and Aliases

  • Create new, clone, delete or purge the index
  • Edit or copy the schema
  • Change number of replicas
  • Backup (dump) the index to a file
  • Restore the index from the backup file
  • Copy the index to another ElasticSearch server
  • Save documents to the file
  • Add, remove and safely rename the alias
  • Migrate legacy types to ElasticSearch 8
Indices and Aliases

Import from SQL databases

  • Microsoft SQL
  • MySQL or MariaDB
