CLI introspection tools for persist

Structs§

BatchPartOutput 🔒
BatchPartUpdate 🔒
BlobArgs: Arguments for commands that run only against the blob store.
BlobBatchPartArgs: Arguments for viewing contents of a batch part
BlobCounts 🔒
D 🔒
InspectArgs: Commands for read-only inspection of persist state
K 🔒: The following is a very terrible hack that no one should draw inspiration from. Currently State is generic over <K, V, T, D>, with KVD being represented as phantom data for type safety and to detect persisted codec mismatches. However, reading persisted States does not require actually decoding KVD, so we only need their codec names to match, not the full types. For the purposes of persistcli inspect, which only wants to read the persistent data, we create new types that return static Codec names, and rebind the names if/when we get a CodecMismatch, so we can convince the type system and our safety checks that we really can read the data.
O 🔒
PrettyBytes 🔒
StateRollupArgs: Arguments for viewing the state rollup of a shard
T 🔒
UnreferencedBlobs 🔒
V 🔒

blob_batch_part: Fetches the updates in a blob batch part
blob_counts: Fetches the blob count for given path
blob_usage: Returns information about blob usage for a shard
consolidated_size 🔒
fetch_latest_state: Fetches the current state of a given shard
fetch_state_diffs: Fetches each state in a shard
fetch_state_rollup: Fetches a state rollup of a given shard. If the seqno is not provided, choose the latest; if the rollup id is not provided, discover it by inspecting state.
fetch_state_rollups: Fetches the state from all known rollups of a given shard
run: Runs the given read-only inspect command.
shard_stats: Rummages through S3 to find the latest rollup for each shard, then calculates summary stats.
unreferenced_blobs: Fetches the unreferenced blobs for given environment
