# pict-rs 0.4.5
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
pict-rs 0.4.5 contains a new commandline option for improving throughput when migrating storage, as
|
||
|
|
well as a change in behavior for the delete endpoint. Additionally there are a few dependency
|
||
|
|
upgrades.
|
||
|
|
|
||
|

## Upgrade Notes
|
||
|
|
|
||
|
|
There's no significant changes from 0.4.4, so upgrading should be as simple as pulling a new version
|
||
|
|
of pict-rs.

### Migration Concurrency
|
||
|
|
|
||
|
|
When migrating from filesystem storage to object storage, pict-rs initially migrated every file
|
||
|
|
sequentially. This was extremely slow, so in 0.4.1 this was made concurrent. Since then, the object
|
||
|
|
storage migration has moved 32 files at a time. This still might be too slow for some large
|
||
|
|
deployments, so pict-rs 0.4.5 is making this value configurable.
|
||
|
|
|
||
|
|
Thew new `--concurrency` flag can be passed to the `migrate-store` subcommand with any integer
|
||
|
|
value. By default, pict-rs sets this value to 32, but for large deployments, setting it to 128, 256,
|
||
|
|
or even 512 might be useful. Note that increasing the concurrency will increase the number of
|
||
|
|
connections to the object storage provider.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
```bash
|
||
|
|
$ pict-rs \
|
||
|
|
migrate-store \
|
||
|
|
--concurrency 32 \
|
||
|
|
filesystem \
|
||
|
|
-p /path/to/files \
|
||
|
|
object-storage \
|
||
|
|
-e https://object-storage-endpoint \
|
||
|
|
-b bucket-name \
|
||
|
|
-r region \
|
||
|
|
-a access-key \
|
||
|
|
-s secret-key \
|
||
|
|
sled \
|
||
|
|
-p /path/to/sled-repo
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
### Inline Delete
|
||
|
|
|
||
|
|
Previously, the endpoint for deleting images would always return an HTTP 204 status after queueing a
|
||
|
|
job to delete the image. This meant that if an invalid `delete token` was provided, or if the
|
||
|
|
deletion failed for some other reason, the client making the request would not be informed of this.
|
||
|
|
pict-rs 0.4.5 now performs this deletion inline to ensure the client is made aware of problems.
