### Write-ahead log (WAL) persistence
InfluxDB writes yet-to-be persisted data to multiple Write-Ahead-Log (WAL) files on local
storage on the [Ingester](/influxdb3/version/reference/internals/storage-engine/#ingester) node before acknowledging the write request.
The Ingester persists the contents of
the WAL to Parquet files in object storage and updates the [Catalog](/influxdb3/version/reference/internals/storage-engine/#catalog) to
reference the newly created Parquet files.
{{% hide-in "clustered" %}}
Parquet data files in object storage are redundantly stored on multiple devices
across a minimum of three availability zones in a cloud region.
{{% /hide-in %}}
The Ingester then writes the contents of
the WAL to Parquet files in object storage and updates the [Catalog](/influxdb3/version/reference/internals/storage-engine/#catalog) to
reference the newly created Parquet files.
If an Ingester node is gracefully shut down (for example, during a new software deployment), it flushes the contents of the WAL to the Parquet files before shutting down.
{{% product-name %}} retains WALs until the data is persisted to Parquet files in object storage.
