With these changes we are now able to peak performances
for all Write() operations across disks HDD and NVMe.
Also adds readahead for disk reads, which also increases
performance for reads by 3x.
IsTruncated should not be set to true if there is no further
possible entries beyond maxKeys.
This commit will also move wide testing on object API from xl
to xl sets.
The problem in current code was we were removing
an entry from a lock lockerMap without considering
the fact that different entry for same resource is
a possibility due the nature of locks that can be
acquired in parallel before we decide if the lock
is considered stale
A sequence of events is as follows
- Lock("resource")
- lockMaintenance(finds a long lived lock in this "resource")
- Owner node rebooted which now retruns Expired() as true for
this "resource"
- Unlock("resource") which succeeded in quorum
- Now by this time application retried and acquired a new
Lock() on the same "resource"
- Now that we have Expired() true from the previous call,
we proceed to purge the entry from the local lockMap()
local lockMap reports a different entry for the expired
UID which results in a spurious log entry.
This PR removes this logging as this situation is an
expected scenario.
This will allow cache to consistently work for
server and gateways. Range GET requests will
be cached in the background after the request
is served from the backend.
Fixes: #7458, #7573, #6265, #6630
This is necessary to avoid connection build up between servers
unexpectedly for example in a situation where 16 servers are
talking to each other and one server now allows a maximum of
15*4096 = 61440 idle connections
Will be kept in pool. Such a large pool is perhaps inefficient for
many reasons and also affects overall system resources.
This PR also reduces idleConnection timeout from 120 secs to 60 secs.
errs was passed to many goroutines but they are all allowed
to update errs if any error happens during deletion, which
can cause a data race.
This commit will avoid issuing bulk delete operations in parallel
to avoid the warning race.
We broke into parts previously as we had checksum for the entire file
to tax less on memory and to have better TTFB. We dont need to now,
after the streaming-bitrot change.
Bulk delete at storage level in Multiple Delete Objects API
In order to accelerate bulk delete in Multiple Delete objects API,
a new bulk delete is introduced in storage layer, which will accept
a list of objects to delete rather than only one. Consequently,
a new API is also need to be added to Object API.
PR #7595 fixed part of the regression, but did not handle the
scenario, where in docker, the internal port is different from
the port on the host.
This PR modifies the regular expression such that all the
scenarios are handled.
Fixes#7619
After recent listing refactor, recursive list doesn't return empty
directories, this commit will fix the behavior and add unit tests
so it won't happen again.
When size is unknown and auto encryption is enabled,
and compression is set to true, putobject API is failing.
Moving adding the SSE-S3 header as part of the request to before
checking if compression can be done, otherwise the size is set to -1
and that seems to cause problems.
Currently we used to reload users every five minutes,
regardless of etcd is configured or not. But with etcd
configured we can do this more asynchronously to trigger
a refresh by using the watch API
Fixes#7515
One user has seen this following error log:
API: CompleteMultipartUpload(bucket=vertica, object=perf-dss-v03/cc2/02596813aecd4e476d810148586c2a3300d00000013557ef_0.gt)
Time: 15:44:07 UTC 04/11/2019
RequestID: 159475EFF4DEDFFB
RemoteHost: 172.26.87.184
UserAgent: vertica-v9.1.1-5
Error: open /data/.minio.sys/tmp/100bb3ec-6c0d-4a37-8b36-65241050eb02/xl.json: file exists
1: cmd/xl-v1-metadata.go:448:cmd.writeXLMetadata()
2: cmd/xl-v1-metadata.go:501:cmd.writeUniqueXLMetadata.func1()
This can happen when CompleteMultipartUpload fails with write quorum,
the S3 client will retry (since write quorum is 500 http response),
however the second call of CompleteMultipartUpload will fail because
this latter doesn't truly use a random uuid under .minio.sys/tmp/
directory but pick the upload id.
This commit fixes the behavior to choose a random uuid for generating
xl.json
Since AssumeRole API was introduced we have a wrong route
match which results in certain clients failing to upload objects
using multipart because, multipart POST conflicts with STS POST
AssumeRole API.
Write a proper matcher function which verifies the route more
appropriately such that both can co-exist.
Other listing optimizations include
- remove double sorting while filtering object entries
- improve error message when upload-id is not in quorum
- use jsoniter for full unmarshal json, instead of gjson
- remove unused code
Allow server to start if one of the local nodes in docker/kubernetes setup is successfully resolved
- The rule is that we need atleast one local node to work. We dont need to resolve the
rest at that point.
- In a non-orchestrational setup, we fail if we do not have atleast one local node up
and running.
- In an orchestrational setup (docker-swarm and kubernetes), We retry with a sleep of 5
seconds until any one local node shows up.
Fixes#6995
In distributed mode, use REST API to acquire and manage locks instead
of RPC.
RPC has been completely removed from MinIO source.
Since we are moving from RPC to REST, we cannot use rolling upgrades as the
nodes that have not yet been upgraded cannot talk to the ones that have
been upgraded.
We expect all minio processes on all nodes to be stopped and then the
upgrade process to be completed.
Also force http1.1 for inter-node communication
common prefixes in bucket name if already created
are disallowed when etcd is configured due to the
prefix matching issue. Make sure that when we look
for bucket we are only interested in exact bucket
name not the prefix.
- [x] Support bucket and regular object operations
- [x] Supports Select API on HDFS
- [x] Implement multipart API support
- [x] Completion of ListObjects support
