v1.12.2

Substreams

• Fix egress bytes calculation when running in noop or dev mode with specified output debug modules.
• Add support to foundation store v2 protocol.
• Reduced memory usage when loading large stores
• Added opt-in memory limits related to loading FullKV stores, gated by environment variables:
  • "SUBSTREAMS_STORE_SIZE_LIMIT_PER_REQUEST" (default allows 5GiB: 5368709120): limit size of all loaded stores for a single request, in bytes. Set to a numeric value in bytes.
  • "SUBSTREAMS_ENFORCE_STORE_SIZE_LIMIT_PER_REQUEST" (default false): if set to true, enforce the limit above instead of just logging a warning
  • "SUBSTREAMS_TOTAL_STORE_SIZE_LIMIT_PERCENT" (default: 75): limit the size in-memory of all loaded stores concurrently on the instance, in percentage of usable memory (cgroup or system total -- regardless of free or available)
  • "SUBSTREAMS_ENFORCE_TOTAL_STORE_SIZE_LIMIT" (default: false): if set to true, enforce the limit above instead of just logging a warning
• Fixed an edge case where substreams with modules depending on stores that start on the future would fail and incorrectly report an error about "tier2 version being incompatible"

Firehose

• Added firehose_session_denied_counter with reason label, increment each time a session is refused with the reason why it was refused.
