ABORTED
Aborted due to cross-transaction contention. This occurs when multiple
transactions attempt to access the same data, requiring Datastore mode
to abort at least one in order to enforce serializability.

This occurs when multiple\ntransactions attempt to access the same data, requiring Datastore mode\nto abort at least one in order to enforce serializability.\n```\n\nTo resolve this issue:\n\n- For rapid traffic increases, Datastore mode attempts to automatically scale to meet the increased demand. When Datastore mode scales, latency begins to decrease.\n- Hot-spots limit the ability of Datastore mode to scale up, review [designing for scale](./best-practices#designing_for_scale) to identify hot-spots.\n- Review [data contention in transactions](/datastore/docs/concepts/transactions#isolation_and_consistency) and your usage of transactions.\n- Reduce the write rate to individual entities.\n\n### RESOURCE_EXHAUSTED\n\nThe following situations can lead to `RESOURCE_EXHAUSTED` errors:\n\nYou exceeded the [free tier quota](/datastore/pricing#free_quota) and billing is not enabled\nfor your project. \n\n```\nRESOURCE_EXHAUSTED\n\nSome resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.\n```\n\nTo resolve this issue:\n\n- Wait for the daily reset of your free tier quota or [enable billing for\n your project](/billing/docs/how-to/modify-project#enable_billing_for_a_project).\n\n### INVALID_ARGUMENT\n\nThe following situations can cause `INVALID_ARGUMENT` errors:\n\n- Attempting to commit an entity with an **indexed** property value greater than 1500 bytes. This limit applies to the UTF-8 encoding of the property value.\n- Attempting to commit an entity with **un-indexed** property values greater than 1,048,487 bytes (1 MiB - 89 bytes). This limit applies to the sum of the property values in an entity. For example, four properties of 256 KiB each exceed the limit.\n\n1,500 bytes (indexed) and 1,048,487 bytes (un-indexed) are\n[limits](/datastore/docs/concepts/limits) for property values. You cannot\nexceed these limits and they are not quotas that can be adjusted. \n\n```\nINVALID_ARGUMENT: The value of property property-name is longer than 1500 bytes\n```\n\nor \n\n```\nINVALID_ARGUMENT: The value of property property_name is longer than 1048487 bytes\n```\n\nTo resolve this issue:\n\n- For indexed property values, split the property into multiple properties. If possible, create an un-indexed property and move data that doesn't need to be indexed into the un-indexed property.\n- For un-indexed property values, split the property into multiple properties or implement compression for the property value."]]
