Previously, CQs with the same name would be stored in the last run map
the same way. This caused only one of the CQs to run because after the
first one ran it would update the last run time for all CQs with the
same name.
Add the database name to the CQ ID in the last run map to differentiate
between CQs in different databases.
Fixes#5814.
Fixes#5612, #5573 and #5518.
Using the MetaExecuter, queries that need to run on both data nodes
and optionally the meta store will be executed across all data nodes
in the cluster.
This fixes a couple of issues with starting meta-only nodes.
1. We were always calling CreateDataNode regardless of whether the the
node is running data services. We only call that now when node is
data enabled.
2. The node.json was created along-side creating the data node. Since
we are not creatinga a data node, this didn't happen anymore. There
wasn't a simple way to do this in one place so it's actually handle
for when creating a meta or a data node now. Since the ID assigned
to the node is the same regardless of role this works in all combinations
of roles.
3. The JoinMetaServer didn't return the ID of the joining node which
created some races when multiple nodes were joining. The join call now
returns that information to the caller.
Fixes#5754
The cache had some incorrect logic for determine when a series needed
to be deduplicated. The logic was checking for unsorted points and
not considering duplicate points. This would manifest itself as many
points (duplicate) points being returned from the cache and after a
snapshot compaction run, the points would disappear because snapshot
compaction always deduplicates and sorts the points.
Added a test that reproduces the issue.
Fixes#5719
Fixes#5653 and #5394.
Previously dropping retention policies did not propogate to local TSDB
shards. Instead, the retention policiess would just be removed from the
Meta Store.
This PR adds ensures that data associated with retention policies is
removed, when the retention policy is dropped.
Also, it cleans up a couple of other methods in `tsdb`, including the
requirement to provide (redundant) shardIDs when deleting databases.
Previously, meta.Client would drop the default retention policy when
trying to create a database with a retention policy. The RPC has now
been modified to include the desired retention policy in the
CreateDatabase command and have it use that retention policy information
instead of the default configuration when provided.
This also lowers the number of RPC calls for
CreateDatabaseWithRetentionPolicy to only a single RPC call instead of
two.
Protections have also been included so creating a retention policy with
different parameters will return an error similar to if you tried to
modify the retention policy separately.
Fixes#5696.
This removes the MetaServers property from node.json to eliminate one
of the four places those addresses are stored on disk. We always use
the values that come through the config (via file, env var or -join arg).
Since we are pinned to go 1.4.3, we're using the same dependency
manager as telegraf to make builds more reproducible. We'll re-evaluate
vendoring when we can move off of 1.4.3.
Previously, the lease redirect was invalid causing anything relying
on a lease for execution (eg. continuous queries) to cease functioning.
The name/nodeid URL param parsing has been moved up to the top of the
handler so the options can be forwarded on to the real leader.
