BREAKING CHANGE: Renamed :timeout to :connection-ttl for clarity. Connection pool options: - :connection-ttl (default: 30000ms) - how long connections live in the pool - :validate-after-inactivity (default: 5000ms) - checks idle connections before reuse, preventing NoHttpResponseException from stale connections - :threads (default: 100) - max total connections in pool - :default-per-route (default: 100) - max connections per route - :insecure? (default: false) - allow self-signed SSL certificates Request timeout options (applied to every request): - :connection-timeout (default: 10000ms) - time to establish TCP connection - :socket-timeout (default: none) - time to wait for response data Also removes deprecated PoolingClientConnectionManager from schema.

Addresses socket timeout errors occurring at exactly 10 seconds for long-running ElasticSearch queries (e.g., queries with 1000+ sub-requests that take several minutes). Root cause: After ductile PR #45 was merged, the new connection management defaults include a 10-second connection-timeout that is being reused as socket-timeout when not explicitly set. This causes intermittent failures for requests that take longer than 10 seconds. Solution: Explicitly set timeout parameters when creating ES connections: - socket-timeout: 600000ms (10 minutes) - allows long-running queries - connection-timeout: 10000ms (10 seconds) - reasonable for establishing connection - validate-after-inactivity: 5000ms (5 seconds) - prevents NoHttpResponseException This is a temporary workaround until ctia's properties schema is updated to support these new ductile parameters (socket-timeout, connection-timeout, validate-after-inactivity) as configurable properties. Related: - ductile PR #45: threatgrid/ductile#45 - Symptom: Requests failing at exactly 10s with socket timeout errors - Evidence: Some requests succeed at 16s, 24s, 28s while others fail at 10s

Fix stale connections and add connection pool configuration
Problem: Production NoHttpResponseException errors caused by stale pooled
connections that the server had closed but the client was still trying to reuse.
Solution: Add validate-after-inactivity option (default: 5000ms) that checks idle
connections before reuse, preventing stale connection errors.
Additional improvements:
default, for long-running operations)
