Neki supports shard-pressure mitigation and resharding without downtime

planetscale.com by Simeon Griggs 7 min read Editor score 6/10

The piece describes how tenant growth and cross-tenant queries can make an initially even tenant-based shard layout unbalanced, and says Neki can adapt resharding without downtime. These are practical trade-offs for systems whose data distribution changes in production.

What
Neki offers tools to mitigate shard pressure and change resharding strategies without downtime.
How
Its declarative data topology guides routing, while tables can be sharded by the columns that best fit their data and queries.
Why it matters
Engineers can adapt shard keys as tenant loads and product requirements change, without taking the database offline.
