The kernel owns the retry loop on the SEA/use_kernel path, so forward the driver's existing ClientConfig retry knobs (the same ones the Thrift HttpRetryPolicy reads) onto the napi ConnectionOptions retry kwargs — keeping SEA and Thrift governed by one retry config. Mirrors Python connector #820. - buildSeaRetryOptions(config): ms -> whole seconds, clamped to napi u32. retryDelayMin->retryMinWaitSecs, retryDelayMax->retryMaxWaitSecs, retriesTimeout->retryOverallTimeoutSecs, retryMaxAttempts passes through as a TOTAL attempt count (the kernel converts to retries-after-first). - SeaBackend.connect() merges it into the native options from the client config. - Adds SeaSessionDefaults retry fields + unit tests (mapping, rounding, clamp). Requires kernel napi retry kwargs (databricks-sql-kernel #141). KERNEL_REV is pinned to #141's branch HEAD as a placeholder — MUST be re-pinned to #141's squash-merge SHA before this merges (orphan-SHA risk otherwise).

What
The kernel owns the retry loop on the SEA (
useSEA/use_kernel) path, so this forwards the driver's existingClientConfigretry knobs — the same ones the ThriftHttpRetryPolicyreads — onto the napiConnectionOptionsretry kwargs. SEA and Thrift are then governed by one retry config. This is the Node analogue of Python connector #820.Changes
buildSeaRetryOptions(config)(lib/sea/SeaAuth.ts) — converts the connector's milliseconds → the kernel's whole seconds, clamped into the napiu32range:ClientConfig(ms / count)retryDelayMinretryMinWaitSecsretryDelayMaxretryMaxWaitSecsretriesTimeoutretryOverallTimeoutSecsretryMaxAttemptsretryMaxAttempts(total attempts — kernel converts to retries-after-first)SeaBackend.connect()merges the retry options (read fromcontext.getConfig()) into the native options.SeaSessionDefaultsgains the four optional retry fields; unit tests cover the mapping, sub-second rounding, and the negative/garbage clamp.retryMaxAttemptspasses through directly because Node's policy (attempt >= retryMaxAttempts) already treats it as a total attempt count, matching the kernel semantics. The default knobs (1s/60s/900s) line up with the kernel defaults.Depends on the napi retry kwargs added in databricks-sql-kernel #141.
KERNEL_REVis pinned to #141's branch HEAD as a placeholder — must be re-pinned to #141's squash-merge SHA before this merges (orphan-SHA risk otherwise). Draft until #141 lands.This pull request and its description were written by Isaac.
