Dictionary keys can be either the service component name (not database name!) or __default__. The latter configuration is applied for every non-matching Mongo component of the service.
Transaction timeouts in POSTGRES_QUERIES_COMMAND_CONTROL override the per-query timeouts in POSTGRES_QUERIES_COMMAND_CONTROL, so the latter are ignored if transaction timeouts are set.

Dynamic config that enables connlimit_mode: auto for PostgreSQL connections. Auto mode ignores static and dynamic max_connections configs and verifies that the cluster services use max_connections equals to PostgreSQL server's max_connections divided by service instance count.
Dynamic config that controls statement metrics settings for specific service.
Dictionary keys can be either the service component name (not database name!) or __default__. The latter configuration is applied for every non-matching PostgreSQL component of the service.
The value of max_statement_metrics controls the maximum size of LRU-cache for named statement metrics. When set to 0 (default) no metrics are being exported.

Proxy for all the HTTP and HTTPS clients. Empty string disables proxy usage.
Proxy string may be prefixed with [scheme]:// to specify which kind of proxy is used. Schemes match the libcurl supported ones. A proxy host string can also embed user and password.
Logging per line and file overrides. Log locations are defined as path prefix from the Arcadia root ("taxi/uservices/services/"). Location of file may be followed by :[line index] to specify 1 exact log in that file.

and 1 log (since exact line is specified) with level TRACE in file "userver/core/src/server/http/http_request_parser.cpp":
If the USERVER_LOG_REQUEST_HEADERS option is enabled, you can control which HTTP headers are logged, including their values. Header is suitable if it exactly matches one of the values in the whitelist. Any headers that are not on the whitelist will have their values replaced with *** in the logs.
Controls whether congestion control limiting of RPS is performed (if main task processor is overloaded, then the server starts rejecting some requests).
