ElasticSearch to SQL sync


(Komal Parekh) #1

Hello,

We are running one application which has very large amount of data updating
very frequently. And we are using SQL for any command like
update/delete/add records. And for querying part we are using
ElasticSearch. So is there any way which syncs my data very frequently say
in 5 to 10 seconds. Is there any push mechanism available with
ElasticSearch which pushes data from SQL to ES? And more what is the best
option for synching? Please reply urgently with the best option :).

Thanks

Best: when you push in your application to MySQL, push as well to elasticsearch.

Thanks David for your prompt response. Actually we are using MSSQL not
MySQL. So this solution will not work for us.

Thanks David for your prompt response. But we want some automatic Push or
poll mechanism for this.

Have you tried the JDBC river for poll mechanism?

Yes we have done some implementation on river but it does not give real
time data. And also it is not as much mature. So for real time data we need
to use some push mechanism which can help up to have realtime data.

As David said, for push, you must modify your middleware that performs the
insert/update/delete - there is nothing ES can do for you. You must add an
ES client that can execute the respective operations on your data against
an ES cluster.

Poll method does not scale, push does scale.

I do not understand JDBC river is not mature, I happily accept bug reports
and patches. Maybe you discovered that river instances do not scale and are
kind of limited.

This is a complex issue with no single, simple, answer. Performing
synchronization between two databases is a non-trivial undertaking for any
technology. For an overview of strategies and techniques please see my
article on the topic Keeping Elasticsearch in Synchttps://www.found.no/foundation/keeping-elasticsearch-in-sync/
