## Problem One doesn't know at tenant creation time how large the tenant will grow. We need to be able to dynamically adjust the shard count at runtime. This is implemented as "splitting" of shards into smaller child shards, which cover a subset of the keyspace that the parent covered. Refer to RFC: https://github.com/neondatabase/neon/pull/6358 Part of epic: #6278 ## Summary of changes This PR implements the happy path (does not cleanly recover from a crash mid-split, although won't lose any data), without any optimizations (e.g. child shards re-download their own copies of layers that the parent shard already had on local disk) - Add `/v1/tenant/:tenant_shard_id/shard_split` API to pageserver: this copies the shard's index to the child shards' paths, instantiates child `Tenant` object, and tears down parent `Tenant` object. - Add `splitting` column to `tenant_shards` table. This is written into an existing migration because we haven't deployed yet, so don't need to cleanly upgrade. - Add `/control/v1/tenant/:tenant_id/shard_split` API to attachment_service, - Add `test_sharding_split_smoke` test. This covers the happy path: future PRs will add tests that exercise failure cases.

### Creates a storage Docker image with postgres, pageserver, safekeeper and proxy binaries.
|
|
### The image itself is mainly used as a container for the binaries and for starting e2e tests with custom parameters.
|
|
### By default, the binaries inside the image have some mock parameters and can start, but are not intended to be used
|
|
### inside this image in the real deployments.
