Pavel Tupitsyn updated IGNITE-16462:
------------------------------------
Description:
TCP connections can enter [half-open
state|https://en.wikipedia.org/wiki/TCP_half-open]: seems to be alive, but any
attempt to send data will fail. Long-living and mostly idle connections are
especially susceptible to this behavior.
Retry mechanism ([IEP-82 Thin Client Retry
Policy|https://cwiki.apache.org/confluence/display/IGNITE/IEP-82+Thin+Client+Retry+Policy])
in thin client implementations partially mitigates the issue. However, not all
operations are safe to retry, and reconnect affects performance.
> Thin client: add keep-alive message to detect half-open connections
