It looks like you're encountering an issue related to the state messages during your sync process. Specifically, the error message indicates that the

getGlobal()

method is returning null, which means that the

AirbyteGlobalState

object is not being properly initialized or populated. Here are a few steps you can take to troubleshoot and potentially resolve this issue: 1. Check Source State Messages: Ensure that your MySQL source is correctly outputting state messages. If the source does not output any state messages, it can lead to issues during the sync process. From the forum post [here](https://discuss.airbyte.io/t/2148), a similar issue was reported:

2022-08-08 10:43:36 INFO i.a.w.g.DefaultReplicationWorker(run):269 - Source did not output any state messages    2022-08-08 10:43:36 WARN i.a.w.g.DefaultReplicationWorker(run):277 - State capture: No new state, falling back on input state: io.airbyte.config.State@3f32a2b3[state={}]

2. Review AirbyteStateMessage Structure: Ensure that the

AirbyteStateMessage

is correctly structured and includes the necessary properties. According to the documentation [here](https://docs.airbyte.com/understanding-airbyte/airbyte-protocol#airbytestatemessage), the

AirbyteStateMessage

should have properties like

shared_state

and

stream_states

. Example structure:

json    {      "shared_state": {        "$ref": "#/definitions/AirbyteStateBlob"      },      "stream_states": {        "type": "array",        "items": {          "$ref": "#/definitions/AirbyteStreamState"        }      }    }

3. Check for Sync Errors: Look for any other errors in the sync logs that might provide more context. For example, a similar issue was reported in a GitHub issue [here](https://github.com/airbytehq/airbyte/issues/28502) where the sync failed due to potentially too small block size: ``` io.airbyte.config.StandardSyncOutput@6802067a[standardSyncSummary=io.airbyte.config.StandardSyncSummary@3736c709[status=failed,recordsSynced=226812,bytesSynced=323572078,startTime=1689815910676,endTime=1689816620161,totalStats=io.airbyte.config.SyncStats@6e44b604[bytesCommitted=0,bytesEmitted=323572078,destinationStateMessagesEmitted=0,destinationWriteEndTime=1689816620160,destinationWriteStartTime=1689815910676,estimatedBytes=<null>,estimatedRecords=<null>,meanSecondsBeforeSourceStateMessageEmitted=0,maxSecondsBeforeSourceStateMessageEmitted=0,maxSecondsBetweenStateMessageEmittedandCommitted=0,meanSecondsBetweenStateMessageEmittedandCommitted=0,recordsEmitted=226812,recordsCommitted=0,replicationEndTime=0,replicationStartTime=1689815910676,sourceReadEndTime=1689816619411,sourceReadStartTime=1689815910717,sourceStateMessagesEmitted=0,additionalProperties={}],streamStats=[io.airbyte.config.StreamSyncStats@1c07c3a5[streamName=chicago_food_inspections,streamNamespace=<null>,stats=io.airbyte.config.SyncStats@64ce2789[bytesCommitted=<null>,bytesEmitted=323572078,destinationStateMessagesEmitted=<null>,destinationWriteEndTime=<null>,

@kapa.ai how can i see airbyte state message

To view the Airbyte state message, you can follow these steps: 1. Access the Airbyte Database: You need to access the internal Postgres database where Airbyte persists its state. You can do this using Docker if you are running Airbyte in a Docker environment. Run the following command to access the Airbyte database:

bash    docker exec -ti airbyte-db psql -U docker -d airbyte

2. Query the State Table: Once you are inside the Postgres database, you can query the

state

table to view the state messages. Use the following SQL command to query the state table:

sql    SELECT * FROM state;

This should return a table with the state information. Here is an example of what the response might look like (note that the response is abbreviated for conciseness):

sql                   id                  |            connection_id             |                                                                                                  state                                                                   |          created_at           |          updated_at           | stream_name | namespace |  type      --------------------------------------+--------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------------------------+-------------------------------+-------------+-----------+--------     884a10a7-1c58-4456-af44-c617eec0c1fb | 78cb42b9-e857-4f93-b159-e590ec31d287 | {"state": {"cdc": false, "streams": [{"cursor": "2022-09-02T07:55:58.324989", "stream_name": "table_one", "cursor_field": ["updated_at"], "stream_namespace": "public"}]}} | 2022-09-01 16:52:44.619871+00 | 2022-09-02 07:59:27.304753+00 |             |           | LEGACY

3. Check the State Message Structure: Ensure that the state message structure is correct. According to the [Airbyte Protocol documentation](https://docs.airbyte.com/understanding-airbyte/airbyte-protocol#airbytestatemessage), the

AirbyteStateMessage

should have properties like

state_type

,

stream

,

global

, and

data

. Example structure:

json    {      "state_type": "GLOBAL",      "global": {        "shared_state": { ... },        "stream_states": [ ... ]      },      "stream": { ... },      "data": { ... }    }

By following these steps, you should be able to view and verify the Airbyte state messages. If you encounter any issues or discrepancies, you may need to check the configuration of your source and destination connectors to ensure they are correctly emitting and handling state messages.

If the

state

table in the Airbyte database is empty, it indicates that no state messages have been recorded. This can happen for several reasons, such as issues with the source connector not emitting state messages or problems during the sync process. Here are some steps you can take to troubleshoot and resolve this issue: 1. Check Source Connector Configuration: Ensure that your MySQL source connector is correctly configured to emit state messages. Verify that the source connector is set up to use incremental syncs, which typically rely on state messages. 2. Review Sync Logs: Examine the sync logs for any errors or warnings that might indicate why state messages are not being emitted. You can access the logs from the Airbyte UI or by checking the log files directly. 3. Verify Source Data: Ensure that there is data in the source MySQL database that can be synced. If the source tables are empty, there may be no state to capture. 4. Run a Test Sync: Try running a test sync with a smaller dataset to see if state messages are emitted. This can help identify if the issue is related to the size or complexity of the data being synced. 5. Check for Known Issues: Review the Airbyte GitHub issues and forum posts for any known issues related to state messages. For example, a similar issue was reported in a GitHub issue [here](https://github.com/airbytehq/airbyte/issues/28502) where the sync failed due to potentially too small block size. 6. Update Connectors: Ensure that you are using the latest versions of the MySQL source and DuckDB destination connectors. Sometimes, updating to the latest version can resolve issues related to state messages. If you continue to experience issues, you may want to reach out to the Airbyte community for further assistance. You can open a new topic on the [Airbyte forum](https://discuss.airbyte.io/) or check for similar issues that have been resolved. By following these steps, you should be able to identify and resolve the issue with the empty

state

table.

@kapa.ai i am also getting warning like missing stats for job 6

It looks like you're encountering a warning related to missing job statistics during your sync process. This issue has been reported by other users as well. Here are some steps you can take to troubleshoot and resolve this issue: ### Steps to Troubleshoot 1. Review the JobHistoryHandler Code: The warning message "Missing stats for job" is generated by the

JobHistoryHandler

class. You can review the relevant code in the Airbyte Platform repository to understand where this is happening: [JobHistoryHandler.java#L144](https://github.com/airbytehq/airbyte-platform/blob/876139deba3d60dacc6d5e5511eb7637918f0e5e/airbyte-commons-server/src/main/java/io/airbyte/commons/server/handlers/JobHistoryHandler.java#L144) This piece of code retrieves job attempt statistics from a

JobPersistence

object and updates corresponding

AttemptRead

objects. The

stat

variable refers to a

JobPersistence.AttemptStats

object containing the statistics for a particular job attempt. 2. Check Environment Variables: Ensure that the environment variables related to state and log storage are correctly set. The original poster in the forum mentioned adding the following variables: -

STATE_STORAGE_GCS_APPLICATION_CREDENTIALS

-

STATE_STORAGE_GCS_BUCKET_NAME

-

WORKER_STATE_STORAGE_TYPE

-

WORKER_LOGS_STORAGE_TYPE

These variables were added to migrate from MinIO to GCS. Verify that these variables are correctly configured and accessible. 3. Verify Configuration Files: Check if any variables were deleted or incorrectly set in the configuration files. For example, you can review the

envMap.json

file to ensure that all necessary environment variables are correctly defined: [envMap.json](https://github.com/airbytehq/airbyte-platform/blob/8ddd99fa7225ba8062af9b3b9f3b274e0cb68464/airbyte-container-orchestrator/src/test/resources/files/envMap.json) ### Example Log Message Here is an example of the warning message you might see in the logs:

The

envMap.json

file is typically used to map environment variables for Airbyte's internal processes. This file is often found in the configuration directories of Airbyte's deployment, especially when using Kubernetes or Docker. ### Locating

envMap.json

in Kubernetes If you are running Airbyte on Kubernetes, the

envMap.json

file is usually uploaded to the pods during the initialization process. You can find references to this file in the logs when the pods are being set up. For example:

plaintext 2024-04-15 16:05:20 platform > Uploading file: envMap.json 2024-04-15 16:05:20 platform > kubectl cp /tmp/642fda08-fba5-45ef-bfeb-042280e4d20f/envMap.json airbyte/orchestrator-repl-job-1052-attempt-0:/config/envMap.json -c init --retries=3

### Locating

envMap.json

in Docker If you are running Airbyte using Docker, the

envMap.json

file might be part of the Docker container's configuration. You can check the container's file system or the directory where you have set up Airbyte. ### Example Path in Kubernetes In a Kubernetes setup, the file might be located in a temporary directory before being copied to the pod. For example:

plaintext /tmp/642fda08-fba5-45ef-bfeb-042280e4d20f/envMap.json

### Example Path in Docker In a Docker setup, you might find it in a similar temporary directory or within the container's configuration directory. ### Steps to Locate

envMap.json

1. Check Initialization Logs: Look at the initialization logs of your Airbyte deployment to see where the

envMap.json

file is being uploaded from and to. 2. Access Pod or Container: Use

kubectl exec

for Kubernetes or

docker exec

for Docker to access the running pod or container and navigate to the directory where the file is located. ### Example Commands For Kubernetes:
