The events API added in 0.25.0 had some reliability issues when a large volume
of events were being emitted. This release addresses that in two ways:
- The gRPC event stream now takes a parameter that sets a batch size. A client
will receive the events when the batch limit is hit. - GraphQL is now limited to one event type per subscription, and we also removed
the ALL event type as an option. This was due to the GraphQL gateway layer
taking too long to process the full event stream, leading to sporadic
disconnections.
These two fixes combined make both the gRPC and GraphQL streams much more
reliable under reasonably heavy load. Let us know if you see any other issues.
The release also adds some performance improvements to the way the core
processes Tendermint events, some documentation improvements, and some
additional debug tools.
