2023.257

Added

  • New configuration option maxRealTimeGap and marginRealTimeGap. They allow to configure a dedicated backfilling stream and to prefer real-time data. The consequence is the reception of out of order records at clients.

Added

  • New config option timeWindowUpdateInterval. This option sets the interval in seconds at which the relative request time window defined by option days and/or daysBefore is updated. Use a value less or equal zero to disable the update. This feature is supported in archive mode only. A typical use case is when data has to be transmitted continuously with a time delay.

timeWindowUpdateInterval=86400

Added

2020-12-17

daysBefore=10

Changed

  • Increase default timeout for acknowledgement messages from 5s to 60s

  • Use microsecond precision in data requests

2020-02-12

Added

  • Backfilling buffer which is a tool to mitigate out-of-order data. Whenever a gap is detected, records will be held in a buffer and not sent out. Records are flushed from front to back if the buffer size is exceeded.

2020-02-10

Changed

  • Subscribe to streams even if the requested end time is before the last received timestamp. This is necessary to do not request data again in case of wildcard requests.

Added
