A Python-based pipeline tool that synchronizes data from a MongoDB cluster to target systems such as Solr, Elasticsearch, or another MongoDB cluster. It performs an initial sync and then tails the MongoDB oplog to keep targets up to date in real time.

Use cases

• sync mongodb data to elasticsearch for search
• replicate a mongodb cluster to another mongodb cluster
• index mongodb collections into solr
• keep a search index in real time with mongodb changes
• stream mongodb oplog changes to another system
• migrate data from mongodb to elasticsearch

When to choose

• you need near-real-time synchronization from MongoDB into Solr or Elasticsearch 1.x-5.x
• you want a mature, community-maintained oplog-tailing pipeline
• you need to replicate MongoDB data to another MongoDB deployment

When to avoid

• you use modern MongoDB change streams instead of oplog tailing
• you target Elasticsearch 6.x or newer, which is unsupported
• you need a managed or cloud-native sync solution
• you require active development or support for recent MongoDB versions
