Apache Ignite Cache - get key from value

Problem

Need to implement a bi-directional key value store. Cache entry is populated into the cache using a key (String) mapping to a value(Long). However, the the cache needs to handle both key->value and value->key lookup. What is the most efficient way to do this?

Note: value->key mapping does not need to be synchronized with key->value in real time, but cannot fall behind key->value mapping for too long (10-15 seconds max).

Naive Ignite Implementation

  1. Use ignite continuous query to monitor changes, upon modification, update another (value->key) cache

Are there better way of achieving this goal? Is ignite the wrong tool to use?

You can use SQL queries and have secondary index on value. Your proposed approach should also work.
