Java time migration guide
editJava time migration guide
editWith 7.0, Elasticsearch switched from joda time to java time for date-related parsing, formatting, and calculations. This guide is designed to help you determine if your cluster is impacted and, if so, prepare for the upgrade.
Convert date formats
editTo upgrade to Elasticsearch 8, you’ll need to convert any joda-time date formats to their java-time equivalents.
Impacted features
editThe switch to java time only impacts custom date
and
date_nanos
formats.
These formats are commonly used in:
If you don’t use custom date formats, you can skip the rest of this guide. Most custom date formats are compatible. However, several require an update.
To see if your date format is impacted, use the deprecation info API or the Kibana Upgrade Assistant.
Incompatible date formats
editCustom date formats containing the following joda-time literals should be migrated.
-
Y
(Year of era) -
Replace with
y
.Example:
YYYY-MM-dd
should becomeyyyy-MM-dd
.In java time,
Y
is used for week-based year. UsingY
in place ofy
could result in off-by-one errors in year calculation.For pattern
YYYY-ww
and date2019-01-01T00:00:00.000Z
will give2019-01
For patternYYYY-ww
and date2018-12-31T00:00:00.000Z
will give2019-01
(counter-intuitive) because there is >4 days of that week in 2019 -
y
(Year) -
Replace with
u
.Example:
yyyy-MM-dd
should becomeuuuu-MM-dd
.In java time,
y
is used for year of era.u
can contain non-positive values whiley
cannot.y
can also be associated with an era field. -
C
(Century of era) -
Century of era is not supported in java time. There is no replacement. Instead, we recommend you preprocess your input.
-
x
(Week year) -
Replace with
Y
.In java time,
x
means zone-offset.Failure to properly convert
x
(Week year) toY
could result in data loss. -
Z
(Zone offset/id) -
Replace with multiple
X
's.Z
has a similar meaning in java time. However, java time expects different numbers of literals to parse different forms.Consider migrating to
X
, which gives you more control over how time is parsed. For example, the joda-time formatYYYY-MM-dd'T'hh:mm:ssZZ
accepts the following dates:2010-01-01T01:02:03Z 2010-01-01T01:02:03+01 2010-01-01T01:02:03+01:02 2010-01-01T01:02:03+01:02:03
In java time, you cannot parse all these dates using a single format Instead, you must specify 3 separate formats:
2010-01-01T01:02:03Z 2010-01-01T01:02:03+01 both parsed with yyyy-MM-dd'T'hh:mm:ssX 2010-01-01T01:02:03+01:02 yyyy-MM-dd'T'hh:mm:ssXXX 2010-01-01T01:02:03+01:02:03 yyyy-MM-dd'T'hh:mm:ssXXXXX
The formats must then be delimited using
||
:yyyy-MM-dd'T'hh:mm:ssX||yyyy-MM-dd'T'hh:mm:ssXXX||yyyy-MM-dd'T'hh:mm:ssXXXXX
The same applies if you expect your pattern to occur without a colon (
:
): For example, theYYYY-MM-dd'T'hh:mm:ssZ
format accepts the following date forms:2010-01-01T01:02:03Z 2010-01-01T01:02:03+01 2010-01-01T01:02:03+0102 2010-01-01T01:02:03+010203
To accept all these forms in java time, you must use the
||
delimiter:yyyy-MM-dd'T'hh:mm:ssX||yyyy-MM-dd'T'hh:mm:ssXX||yyyy-MM-dd'T'hh:mm:ssXXXX
-
d
(Day) -
In java time,
d
is still interpreted as "day" but is less flexible.For example, the joda-time date format
YYYY-MM-dd
accepts2010-01-01
or2010-01-1
.In java time, you must use the
||
delimiter to provide specify each format:yyyy-MM-dd||yyyy-MM-d
In java time,
d
also does not accept more than 2 digits. To accept days with more than two digits, you must include a text literal in your java-time date format. For example, to parse2010-01-00001
, you must use the following java-time date format:yyyy-MM-'000'dd
-
e
(Name of day) -
In java time,
e
is still interpreted as "name of day" but does not parse short- or full-text forms.For example, the joda-time date format
EEE YYYY-MM
accepts bothWed 2020-01
andWednesday 2020-01
.To accept both of these dates in java time, you must specify each format using the
||
delimiter:cccc yyyy-MM||ccc yyyy-MM
The joda-time literal
E
is interpreted as "day of week." The java-time literalc
is interpreted as "localized day of week."E
does not accept full-text day formats, such asWednesday
. -
EEEE
and similar text forms -
Support for full-text forms depends on the locale data provided with your Java Development Kit (JDK) and other implementation details. We recommend you test formats containing these patterns carefully before upgrading.
-
z
(Time zone text) -
In java time,
z
outputs Z for Zulu when given a UTC timezone.
Test with your data
editWe strongly recommend you test any date format changes using real data before deploying in production.
Update index mappings
editTo update joda-time date formats in index mappings, you must create a new index with an updated mapping and reindex your data to it.
The following my-index-000001
index contains a mapping for the datetime
field, a
date
field with a custom joda-time date format.
GET my-index-000001/_mapping
{ "my-index-000001" : { "mappings" : { "properties" : { "datetime": { "type": "date", "format": "yyyy/MM/dd HH:mm:ss||yyyy/MM/dd||epoch_millis" } } } } }
To change the date format for the datetime
field, create a separate index
containing an updated mapping and date format.
For example, the following my-index-000002
index changes the datetime
field’s
date format to uuuu/MM/dd HH:mm:ss||uuuu/MM/dd||epoch_millis
.
PUT my-index-000002 { "mappings": { "properties": { "datetime": { "type": "date", "format": "uuuu/MM/dd HH:mm:ss||uuuu/MM/dd||epoch_millis" } } } }
Next, reindex data from the old index to the new index.
The following reindex API request reindexes data from
my-index-000001
to my-index-000002
.
POST _reindex { "source": { "index": "my-index-000001" }, "dest": { "index": "my-index-000002" } }
If you use index aliases, update them to point to the new index.
POST /_aliases { "actions" : [ { "remove" : { "index" : "my-index-000001", "alias" : "my-index" } }, { "add" : { "index" : "my-index-000002", "alias" : "my-index" } } ] }
