Building modern applications often requires the ability to perform full-text searches with fuzzy matching capabilities on data that’s primarily stored in NoSQL databases like DynamoDB. While DynamoDB excels at fast key-based lookups and can handle massive scale, it lacks the sophisticated search capabilities that applications need for features like autocomplete, typo-tolerant search, and complex text analysis. OpenSearch (the open-source fork of Elasticsearch) provides these advanced search capabilities, but keeping it synchronized with your primary data store presents unique challenges.
