Webb6 apr. 2024 · How you decide to split up your data into shards – also referred to as your partition strategy – should be a direct function of how your business runs, and where your query load is concentrated. For a B2B SaaS company where every user belongs to an organization, sharding by splitting up organization-level data probably makes sense.

WebbUnlike hash-based sharding which uses a fixed hash function and range-based sharding which requires us to specify a range in advance, directory-based sharding allows you to use whatever system or algorithm we want to use to assign data entries to shards, and also it relatively easy to dynamically add shards using this approach. WebbNow we explore sharding modes with finer focus on load balance: row-wise. Row-wise is specifically addressing large tables which a single device cannot hold due to the memory size increase from large embedding row numbers. It can address the placement of the super large tables in your models.
