Sharding Strategy
Choosing the right number of shards is critical. Too many shards can lead to overhead, while too few can limit scalability.
Recommendations:
- Small Indices: Use a single shard if the index is expected to remain small (e.g., less than a few GB).
- Large Indices: Use multiple shards if the index is expected to grow significantly. Monitor shard sizes and adjust accordingly.
Example: Creating an Index with Multiple Shards
