Memory Batch Ingestion Concurrency Limit
To prevent server overload, Hana caps the number of memory batch ingestions a single user can run at the same time. When you reach this threshold, new ingestion requests are rejected until one of the active ingestions completes. This ensures faster, more predictable ingestion for everyone.
The current limit is 3 concurrent memory batch ingestions per user. Plan your uploads accordingly to avoid errors.
Tips
- Queue large sources during off‑hours to finish sooner.
- Group related docs into a single batch where possible.
- Start with a small test batch to verify access and formatting before scaling up.
Example
If you try to start a fourth ingestion while three are running, the UI will display an error like Maximum concurrent ingestions reached. Wait for one batch to complete (status INGESTED) before launching the next. This avoids partial failures and gives clearer progress feedback to your team.
