Refactors the WKT and GeoJSON parsers from an utility class into an
instantiatable objects. This is a preliminary step in
preparation for moving out coordinate validators from Geometry
constructors. This should allow us to make validators plugable.
Allow querying of FROZEN indices both through dedicated SQL grammar
extension:
> SELECT field FROM FROZEN index
and also through driver configuration parameter, namely:
> index.include.frozen: true/false

(cherry picked from commit 2445a933915f420c7f51e8505afa0a7978ce6b0f)
Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2.
Queries that are supported as a result of this initial implementation
Metadata commands
- `DESCRIBE table` - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly.
Returning geoshapes and geopoints from elasticsearch
- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;
Using geopoints to elasticsearch
- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes.
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.
Limitations:
Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

Properly treat '%' as a wildcard for catalog filtering instead of doing
a straight string match.
Table filtering now considers aliases as well.
Add escaping char for LIKE queries with user defined params
Fix monotony of ORDINAL_POSITION
Add integration test for SYS COLUMNS - currently running only inside
single_node since the cluster name is test dependent.
Add pattern unescaping for index names
Fix#40582
(cherry picked from commit 8e61b77d3f849661b7175544f471119042fe9551)
Changed the JDBC metadata to return empty results sets instead of
throwing SQLFeatureNotSupported as it seems a more safer/compatible
approach for consumers.
Fix#40533
(cherry picked from commit ef2d2527c2b5140556fd477e7ff6ea36966684da)
TimeProcessor didn't implement `getWriteableName()` so the one from
the parent was used which returned the `NAME` of the parent. This
caused `TimeProcessor` objects to be deserialised into
DateTimeProcessor.
Moreover, added a restriction to run the TIME related integration tests
only in UTC timezone.

SYS TABLES meta command has been improved to better adhere to the ODBC
spec in particular with regards to the handling of enumerations (and
the differences between '%', null and ''(empty string))
Fix#40348
(cherry picked from commit e3070615000228c283d17ce8d182b44f1450a5d5)
Previously, `getTime(colIdx/colLabel)` and
`getObject(colIdx/colLabel, java.sql.Time.class)` methods were computing
the time from a `ZonedDateTime` by applying day in millis modulo on the epoch millis
of the `ZonedDateTime` object. This is wrong as we need to keep the time
related fields at the timezone of the `ZonedDateTime` object and just
set the date info to the epoch date (01/01/1970).
Additionally fixes a testing issue as the original timezone id is converted
to an offset string when parsing the response from the server.
Previously, `getDate(int columnIdx)/getDate(String columnLabel)` and
were using legacy`java.util.Calendar` instead of the the `java.time.*`
classes to reset to the start of day. This resulted in different results
for certain timestamps and timezones when calling
`getDate(col)` vs`getObject(col, java.sql.Date)`
Now only the methods (that must be implemented due to the JDBC spec)
`getDate(int columnIdx, Calendar cal)/getDate(String columnLabel, Calendar cal)`
are still using the `java.util.Calendar` for those conversion.
The same change was applied to
`getTime(int columnIdx)/getTime(String columnLabel)`
and
`getTimestamp(int columnIdx)/getTimestamp(String columnLabel)`
Fixes: #40289
(cherry picked from commit 44560671f18397e0c58e3647732880fcb73a5034)
Previously, calling getDate()/getTime()/getTimestamp() and getObject()
with the corresponding java.sql class on a column of SQL DATE type from
the JDBC result set would throw an Exception.
For cases where fields can have multi values, allow the behavior to be
customized through a dedicated configuration field.
By default this will be enabled on the drivers so that existing datasets
work instead of throwing an exception.
For regular SQL usage, the behavior is false so that the user is aware
of the underlying data.
Fix#39700
(cherry picked from commit 2b351571961f172fd59290ee079126bbd081ceaf)
Previously, JDBC's REST call to the server was always sending UTC
instead of the timezone passed through connection string/properties.
Moreover the conversion to java.sql.Date was problematic as a
calculation on the epoch millis was used to set the time to 00:00:00.000
and the timezone info was lost. This caused the resulting java.sql.Date
object which is always using the JVM's timezone (no matter what timezone
setting is used in the connection string/properties) to be wrongly created.
Fixes: #39915
* Add "columnar" option for REST requests (but be lenient for non-"plain"
modes) for json, yaml, smile and cbor formats.
* Updated documentation
(cherry picked from commit 5b7e0de237fb514d14a61a347bc669d4b4adbe56)
This defaults to "true" (current behavior) and will throw an exception
if there is a property that cannot be recognized. If "false", it will
ignore anything unrecognizable.
(cherry picked from commit 38fbf9792bcf4fe66bb3f17589e5fe6d29748d07)
* Added SSL configuration options tests
Removed the allow.self.signed option from the documentation since we allow
by default self signed certificates as well.
* Added more tests
* Add separate CLI Mode
* Use the correct Mode for cursor close requests
* Renamed CliFormatter and have different formatting behavior for CLI and "text" format.
* SQL: Rename SQL data type DATE to DATETIME
SQL data type DATE has only the date part (e.g.: 2019-01-14)
without any time information. Previously the SQL type DATE was
referring to the ES DATE which contains also the time part along
with TZ information. To conform with SQL data types the data type
`DATE` is renamed to `DATETIME`, since it includes also the time,
as a new runtime SQL `DATE` data type will be introduced down the road,
which only contains the date part and meets the SQL standard.
Closes: #36440
* Address comments
As the internals have moved to java.time, the usage of TimeZone itself
should be minimized as it creates issues when being converted to ZoneId
Protocol wise the two are mostly identical so consumer should not see
any difference.
Note that terminology wise, inside the docs, the public API and inside
the protocol timeZone will continue to be used as it's more widely
understood as oppose to zoneId which is an implementation detail
specific to the JVM
Fix#36535
Introduce Histogram grouping function for bucketing/grouping data based
on a given range. Both date and numeric histograms are supported using
the appropriate range declaration (numbers vs intervals).
SELECT HISTOGRAM(number, 50) AS h FROM index GROUP BY h
SELECT HISTOGRAM(date, INTERVAL 1 YEAR) AS h FROM index GROUP BY h
In addition add multiply operator for Intervals
Add docs for intervals and histogram
Fix#36509
Move classes under the same package to avoid internal classes being
exposed to the outside. Remove public visibility outside 3 classes:
EsDriver, EsDataSource and EsTypes.
The driver only has one package, namely org.elasticsearch.xpack.sql.jdbc
Use Es prefix for classes to ease name conflict and indicate their
destination
Fix#35437
This commit adds back bundling of all deps of the sql jdbc jar. This was
lost in a refactoring of how the shadow plugin is handled for the entire
elasticsearch project.
Introduce INTERVAL as a DataType
Add INTERVAL to the grammar which supports the standard SQL declaration
(without precision):
> INTERVAL '1 23:45:01.123456789' DAY TO SECOND
but also number for single unit intervals:
> INTERVAL 1 YEAR
as well as the plurals of the units:
> INTERVAL 2 YEARS
Interval are internally supported as just another Literal being backed
by java.time.Period and java.time.Duration
Move JDBC away from JDBCType enum to SQLType interface
Refactor DataType by moving it into server core and adding dedicated (and
much simpler) JDBC driver type
Improve internal JDBC conversion by normalizing on the DataType
Rename JDBC columnInfo to JdbcColumnInfo to differentiate between it and
the SQL ColumnInfo
Fix#29990
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
We're publishing jdbc into our maven repo as though its artifactId is
`x-pack-sql-jdbc` but the pom listed the artifactId as `jdbc`. This
fixes the pom to line up with where we're publishing the artifact.
Closes#34399
* New OCTET_LENGTH function
* Changed the way the FunctionRegistry stores functions, considering the alphabetic ordering by name
* Added documentation for the RANDOM function
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
* Added TRUNCATE function, modified ROUND to accept two parameters instead of one. Made the second parameter optional for both functions.
* Added documentation for both functions.
