You can no longer specify a different ORDER BY clause in a subquery than
|
|
the one in the top level query. This functionality never worked properly,
|
|
but was not explicitly forbidden.
|
|
|
|
As part of the ongoing development of the tsi1 index,
|
|
the implementation of a Bloom Filter, used to efficiently determine
|
|
if series are not present in the index, was altered in #8857. While
|
|
this significantly increases the performance of the index and reduce
|
|
its memory consumption, the existing tsi1 indexes created while
|
|
running previous versions of the database are not compatible with 1.4.0.
|
|
|
|
Users with databases using the tsi1 inde
|
|
must go through the following process to upgrade to 1.4.0:
|
|
|
|
1. Stop influxd.
|
|
2. Remove all index directories on databases using the tsi1 index.
|
|
With default configuration these can be found in
|
|
/var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index
|
|
or ~/.influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index.
|
|
It's worth noting at this point how many different shard_ids you visit.
|
|
3. Run the influx_inspect inmem2tsi tool using the shard's
|
|
data and WAL directories for -datadir and -waldir, respectively.
|
|
Given the example in step (2) that would be influx_inspect
|
|
inmem2tsi -datadir /var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID
|
|
-waldir /path/to/influxdb/wal/DB_NAME/RP_NAME/SHARD_ID.
|
|
4. Repeat step (3) for each shard that needs to be converted.
|
|
5. Start influxd.
|
|
|
|
Users with existing tsi1 shards, who attempt to start version 1.4.0 without
|
|
following the above steps, will find the shards refuse to open,
|
|
and will most likely see the following error message:
|
|
|
|
incompatible tsi1 index MANIFEST
