List Recent Connections

The maximum number of connections to return. If unspecified or 0, a default value may be applied. The server may return fewer connections than requested due to memory constraints; the limit is set to allow listing all connections for a single broker. Consider filtering by node_id to view connections for specific brokers. Note that paging is currently not fully supported, and this field only acts as a limit for the first page of data returned. Subsequent pages of data cannot be requested.

Filter expression to apply to the connection list. Uses a subset of AIP-160 filter syntax supporting:

• Field comparisons (=, !=, <, >, <=, >=)
• Logical AND chaining: condition1 AND condition2
• Nested field access: parent.child = value
• Escape sequences: field = "string with "quotes""
• Enum types
• RFC3339 timestamps and ISO-like duration

Limitations (not supported):

• Logical OR chaining
• Parentheses ( ) for grouping
• Map and repeated types
• HAS (:) operator
• Negation (-, NOT)
• Bare literal matching

Example filters:

• state = KAFKA_CONNECTION_STATE_OPEN
• idle_duration > 30s AND total_request_statistics.request_count > 100
• authentication_info.user_principal = "my-producer"
• recent_request_statistics.produce_bytes > 1000 AND client_software_name = "kgo"
• open_time >= 2025-09-01T10:22:54Z

Field-based ordering specification following AIP-132 syntax. Supports multiple fields with asc/desc direction indicators. Examples:

• idle_duration desc - longest idle connections first
• open_time desc, total_request_statistics.request_count desc - newest connections first, then most active
• recent_request_statistics.produce_bytes desc - connections with highest current produce throughput first
