Pgloader hangs on copying rows when migrating from maria db.

[coreylarew]

I am currently trying to migrate my Apache Guacamole DB, which currently resides in MariaDB, to PostgresSQL. The schema and all tables are created. However when it starts the copy of rows process it just hangs there.

I deploy postgres, mariadb, and pgloader in kubernetes.

PGLOADER Deployment yml:

apiVersion: batch/v1 kind: Job metadata: name: pgloader namespace: paas-admin spec: template: metadata: annotations: sidecar.istio.io/inject: "false" spec: containers:

• name: pgloader image: ghrc.io/dimitri/pgloader command: ["pgloader", "--verbose", "--debug", "/tmp/myload/my.load"]

  command: ["/bin/bash", "-c", "--"]

  #        args: [ "while true; do sleep 30; done;"]
  volumeMounts:
  - name: config-volume
    mountPath: /tmp/myload

  volumes:

  • name: config-volume configMap: name: myload items:
    • key: my.load path: my.load restartPolicy: Never backoffLimit: 4

PGLOADER Load File

load database from mysql://user:pass@mariadb-svc:3306/guacamole_db into postgresql://user:pass@paas-pg-pgpool:5432/guacamole_db

WITH workers = 8, concurrency = 1, create no indexes, multiple readers per thread, rows per range = 10000

CAST type int when (= 11 precision) to "integer" drop typemod

ALTER SCHEMA 'guacamole_db' RENAME TO 'public';

I might think that this is because of scram-sha-256 which the tool not supports.
