I have 2 separate MSSQL databases and would like to extract data from them, combine it and send it to ES for indexing. Can Logstash connect to more than 1 MSSQL database, retrieve certain data from them then combine the retrieved datasets into 1 document and send it to ES for indexing? Thank you ---

logstash can certainly connect to more than one database. It is possible you would want to use an [aggregate](https://www.elastic.co/guide/en/logstash/current/plugins-filters-aggregate.html) filter to combine events, or perhaps use data from one database to enrich documents from the other using either a jdbc\_streaming or jdbc\_static filter. ---
