Incremental data

I have some records already existed in table.I have modified some records after pushed into the table.but the modified data was not reflected in elastic to achieve this?

Hi @chelseia.

Please use below config file for logstash to get incremental update in existing elastic search index.

input {
  jdbc {
    jdbc_driver_library => "C:\Users\XXX\Downloads\Elasticsearch\sqljdbc_4.2\enu\jre8\sqljdbc42.jar"
    #jdbc_driver_class => ""
	jdbc_driver_class => ""
    jdbc_connection_string => "jdbc:sqlserver:XXXXX;integratedSecurity=false;"
    jdbc_user => "USER"
	jdbc_password => "PASSWORD"
	jdbc_validate_connection => true
	tracking_column => "dateinserted"
	use_column_value =>true

    statement => "SELECT * FROM COURSE where dateinserted >:sql_last_value;"
	last_run_metadata_path => "C:\Users\Ramesh.kumar\.logstash_jdbc_last_run"
	#schedule => "* * * * * *"

output {
  elasticsearch {
    document_id => "%{id}"
	document_type => "_doc"
    index => "dbdataindex_testauto"
	hosts => ["localhost:9200"]
  codec => rubydebug

Note-please modify the logstash.config as per your information.
un-comment #schedule => "* * * * * *" if you want to provide schedule time


Thank you.but I dont have any date column to use as the sql_last_value.and my table consist of neither timestamp nor incremental how to achieve the real time data using logstash?

Hi @chelseia.

you can use separate row0num or create separate row-num columns= in sql query and store into elastic search as index then second time trace this column - row-num?

you will get unique records /every time your scheduler will get newly data and updated data ?
