-- partitioned, so existing installs are unaffected until you run this.
--
-- IMPORTANT
-- * After partitioning, `prisma db push` (including the proxy's
-- --use_prisma_db_push startup mode) is NOT supported: it tries to rewrite
-- the primary key back to ("request_id"), which Postgres rejects on a
-- partitioned table. The proxy detects this and exits with guidance.
-- Use the default startup path (`prisma migrate deploy`) instead.
-- * Test on a staging copy first and take a backup.
-- * Postgres cannot convert a populated table to partitioned in place, so this
-- renames the old table aside and creates a fresh partitioned table.

"""Name the deployment whose payload the gateway, not the client, put breakpoints on.
Spend accounting only asks whether litellm acted, so what it needs is which
deployment, not a count. Recording that is what makes the mark attempt-scoped: the
metadata bucket is one dict shared by every retry, failover and fallback of a
request, and ``litellm_call_id`` is shared with it, so anything request-scoped
written by one attempt is read by all of them and each boundary would have to
remember to strip it. The deployment is the part that actually changes when the
request moves, so a leg that injected nothing is never credited for one that did.
It also makes a zero delta (hook re-entry) and a negative one (a prompt manager
replacing the messages) harmless, since neither rewrites an earlier mark.
A pass that runs before a deployment is chosen, which is what the proxy does for
prompt templates, injects into the payload every leg goes on to send, so it marks
the request for all of them rather than for one.
Only what this pass actually placed counts. A ``tool_config`` point is placed by
the Bedrock converse transform, and only when the request carries tools, so the
presence of one here says nothing about whether a breakpoint reaches the wire;
claiming it marked three request shapes out of four that inject nothing. Missing
that Bedrock credit is the fail-closed direction, and the alternative is a
provider transform that carries spend-attribution state.
Reads whichever bucket the request actually carries rather than asking the shared
name resolver, which answers on key presence: ``litellm_params`` declares
``litellm_metadata`` as None on every request, so the resolver names a bucket that
is not there and the mark is dropped.
Never CREATES the bucket. The proxy seeds it on every request and is the marker's
only reader, so a request without one is a bare SDK call nothing would consume it
from. Creating it would also add a key to a dict call sites splat as ``**kwargs``,
and on the Responses API ``metadata`` is both this bucket's default name and an
explicit parameter, so the splat collides with the caller's own value.

New Relic Metric API Integration - sends per-team cost/usage metrics to /metric/v1
NR Reference API: https://docs.newrelic.com/docs/data-apis/ingest-apis/metric-api/introduction-metric-api/
`async_log_success_event` / `async_log_failure_event` queue one record per request;
at flush the queue is aggregated by (team, model group, model, provider, status)
into count/summary metrics. `interval.ms` is the real window between flushes,
computed at flush time.
Team-scoped by construction: the ingest key is injected explicitly and there is
deliberately no environment-variable fallback, so a team's metrics are never sent
with the proxy operator's credentials (mirrors ``allow_env_credentials=False`` on
the Datadog team logger).
Error policy on flush: 4xx drops the batch (a retry would fail identically; 403
is a permanent credential failure), 5xx/network re-queues capped at
``max_queue_size`` records with the oldest dropped.
For batching specific details see CustomBatchLogger class

MCP spans (``MCP_TOOL_CALL``, ``MCP_LIST_TOOLS``) have two shapes, chosen at emit
time by :func:`resolve_mcp_span_context`. When the client propagates trace context
in ``params._meta`` MCP and the HTTP transport are independent contexts per the
OTel GenAI MCP semconv, so the span parents to that propagated context and records
the ``PROXY_REQUEST`` transport span as a span *link*, never a parent — the shape

The transport comes from :func:`_mcp_transport_span_context`, which is the
*current message's* POST rather than whatever request happened to open the

request.
When the client propagates W3C trace context in the request's ``params._meta``

streamable-HTTP session multiplexes many messages, and the client's own span is
the truthful parent. So, per the OTel GenAI MCP semconv:
(SEP-414), that remote context is recorded as a span *link*, never the parent.
The OTel GenAI MCP semconv prefers the inverse (remote parent, transport link),
but the gateway's tracing backend only ever receives the gateway's half of such
a trace: parenting into the client's trace id roots the span in a trace whose
root span never reaches the backend, so the span is unreachable from the trace
view and the transport transaction shows a dangling link (observed with
clients that propagate synthetic trace ids). Anchoring to the gateway's own
request and linking the client's context keeps every trace renderable while
preserving the client-side correlation.

* record the transport span as a *link*, never the parent.
Almost no client implements SEP-414 yet, so in practice nothing is propagated.
Rooting the span there splits a single tool call into two disconnected traces
joined only by a link, which is how it surfaces in APM: the ``POST`` transaction
and the ``tools/call`` span share no trace. With no remote parent to honor,
parent to the transport span of the request carrying this message instead, so
the call stays in one trace; no link is added since the transport is now the
real parent. The transport comes from :func:`_mcp_transport_span_context`, which
is the *current message's* POST rather than whatever request happened to open
the session, so a long-lived session does not glue every message under its
first request. With neither a remote parent nor a transport the returned context
carries no span and the span legitimately starts its own root trace.
With no transport at all the span starts its own root trace, still carrying
the link — the client context is only ever a link, so this event keeps one
shape everywhere. Both returned contexts are built on an explicitly empty
base, so ambient (stale session) state can never leak in, and the span
inherits the transport's sampling decision exactly like every other
request-level span — a client's sampled flag neither forces nor suppresses
recording.

A Claude-family target is recognized by name, which says nothing about the carrier the
provider serving it accepts: Snowflake serves Claude over the Anthropic dialect and
declares ``thinking`` alone, so storing the tier there raises before the request reaches
the wire.
Without a resolved provider the tier stays behind, which is what this bridge sent before
it carried one at all. Reading the declaration from the model's own prefix instead would
resolve the provider through a lookup that runs an OAuth device flow for two of them, and
this runs inside a logging callback as well as on the request path.
Unlike ``_supports_prompt_cache_key`` this does not exclude a provider that proxies an
unknown backend, because that provider declares this param and forwards it to a proxy
that resolves the real target itself, where a derived cache key has no such guarantee.

"""Translate Anthropic thinking to either thinking or reasoning_effort.
A Claude-family target keeps ``thinking`` verbatim, since every bridged provider serving one
speaks that param. Carrying its adaptive effort tier alongside takes two different params,
because the two are not interchangeable at the provider mapping below.
Bedrock takes ``output_config`` directly, which attaches the tier and leaves ``thinking``
alone. Another bridged Claude target takes ``reasoning_effort`` if it declares that param,
and used to be sent no tier at all, so an adaptive request arrived byte-identical whichever
effort the caller asked for. That tier stays a plain string there, since the summary it
would otherwise be wrapped with already travels inside the forwarded ``thinking`` block,
and the wrapped dict is rejected outright by some of these providers.
A target declaring neither carrier keeps its bare ``thinking`` block. Being Claude-family
is a fact about the model, not about the params the provider in front of it accepts, so
the tier is offered only where the target says it is taken.
``reasoning_effort`` is not a substitute for ``output_config`` on the Bedrock side: an
application inference profile ARN resolves to neither, so the tier is dropped, and providers
that rebuild ``output_config`` from it overwrite a caller-set ``thinking.display`` doing so.
An adaptive request with no tier stays untouched either way, so the provider's own default
still applies.

A deployment that refuses every step of a chain falls back to an accepted level read off that

never degraded to, being an off switch rather than a tier; an always-on-thinking model is
