Event-driven search

For fast and valuable decisions




In the modern world of realtime data streams it's never been more challenging to find a needle in the haystack.

Using a conventional search, it's necessary to query again and again to get updates from a changing data. This approach is also known as polling. The polling wastes the value of results by increasing the latency. Moreover, it increases the cost.

Instead, an efficient solution should push query results immediately once available. And when query number is high, just pushing everything to everyone is not viable.

So there's a demand to filter the data streams to receive only what is important. Some stream analytics solutions like Apache Flink ⧉ or AWS Kinesis ⧉ are present to fulfill it. However, in the existing solutions, every incoming event is matched to every registered query. Given the fixed incoming events rate, the cost is in direct ratio to query number. It's better than polling, but still not cost-efficient.

There is the reverse search index approach to find queries by data. This enables the efficient query number scaling. Some reverse search solutions are present: Elasticsearch Percolator ⧉ and Lucene Monitor Query ⧉. Unfortunately, these solutions are polling-based and not event-driven.

How it works

figure: how it works
A user defines a subscription with matching conditions.
Awakari consumes events from an arbitrary sources.
Every incoming event triggers the matching subscriptions search.
Every matching subscription is used to notify the linked user.
A user is also able to publish own events to Awakari.
