MeshLine
A practical example
Example: a B2C platform with 400 million contact records shards its database by user ID range, so each server holds a subset and lookups route to the right shard.
A B2B team with two million contacts would gain nothing from the same design.
What to evaluate before investing
- Ask whether the database scales vertically first and what its practical ceiling is.
- Check how cross-shard queries and joins perform, since they are the usual pain point.
- Confirm how shard rebalancing and key selection are handled if data skews toward one shard.
Limitations and tradeoffs
Tradeoff: sharding buys scale at the price of operational complexity: cross-shard joins get slow, transactions spanning shards are hard, and a bad shard key is painful to change. Most marketing data volumes never need it.
