Feature: Sharding: Vshard

    • Closed Issue created by Sergey V @sv

    Picodata should run Vshard router and storage on every instance in a cluster and automatically manage vshard configs.

    On each instance after the instance has started:

    • Vshard storage and router API should be available.
    • Global vshard variable should be set so that vshard.router and vshard.storage would be available.
    • vshard.router.callrw should work.
    • Bucket count and other parameters should be chosen to be reasonable defaults for the most use cases.

    Picodata should not require additional parameters or env variables to setup vshard.

    Motivation

    Sharding, scaling. Vshard works somehow. There are no other options that are ready to use.

    To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
