How much data can Elasticsearch hold? There are no hard limits on shard size, but experience shows that shards between 10GB and 50GB typically work well for logs and time series data. You may be able to use larger shards depending on your network and use case. Smaller shards may be appropriate for Enterprise Search and similar use cases.
