 9 | ## Context
10 | 
11 | There is a need of having an API exposed which can be used to search enterprise wide common data model.
12 | 
13 | The data currently resides in a RDBMS database, it is difficult to expose micro-services directly querying out of RDBMS databases since the application runs out the same environment. 
14 | 
15 | There are options like ElasticSearch or Solr where data can be replicated.  
16 | 
17 | ## Decision
18 | 
19 | Use ElasticSearch for data indexing
20 | 
21 | ## Consequences
22 | 
23 | Data needs to be replicated across the ElasticSearch cluster. This separate cluster needs proper maintenance. 
24 | 
25 |  * Near-real time data replication is required.
26 |  * Additional cost of maintaining the ElasticSearch environments
