Struct BalancedSharding 

Source 
pub struct BalancedSharding { /* private fields */ }
Expand description

The Apache Iggy producer/consumer escape hatch: same types Topic::iggy_producer/Topic::iggy_consumer/Topic::iggy_consumer_group return, and the stored message a failed publish hands back, re-exported so reaching for them doesn’t need an iggy dependency of your own. A simple round-robin sharding strategy. Distributes messages evenly across all shards by incrementing an atomic counter.

WARNING: This strategy does NOT preserve message ordering across shards. Messages to the same stream/topic may be processed out of order. Use OrderedSharding if message ordering is required.
