Add support for custom date formats and OpenSearch date formats for date fields as part of Lucene query #2762

manasvinibs · 2024-06-18T22:46:47Z

Description

This change adds support for OpenSearch Date formats and custom date formats to be part of SQL Lucene queries.
Without this change, we are supporting only list of selected formats which always gets formatted to ISO local string or epoch before submitting to opensearch dsl query.

Refactors ExprType to be OpenSearchDateType object instead of ExprCoretype enums passed as a param to the Lucene QueryBuilder.
Extract OpenSearchDateNamedFormatters and OpenSearchDateCustomFormatters from the OpenSearchDateType object which is set during IndexMapping field parsing for a field type.
Format information is passed to the ExprValue implementation constructor to parse the date string using the field specific formatters.
Adds unit tests for all the different formats use cases.
Adds OpenSearch package dependency to the core module to use OpenSearch provided DateFormatter and DateFormatters classes instead of java provided DateFormatter.

Follow-up PR - I'll add IT tests in a separate PR

  /** Constructor of ExprDateValue. */
  public ExprDateValue(String date) {
    try {
      this.date = LocalDate.parse(date, DATE_TIME_FORMATTER_VARIABLE_NANOS_OPTIONAL);
+      this.datePattern = determineDatePattern(date);


does parese execute 2 times, the reasons is LocalDate.parse already parse the date string

On line #44 here, yes we are already parsing the date string to Local date object. But I need to know the exact pattern that matched the input date string. So inside determineDatePattern function, using parse function (LocalDate/LocalDatetime) I'm determining the matching pattern and returning that to set this.datePattern. This date pattern is used to format the LocalDate date object instead of default ISO_LOCAL_DATE string inside value().

Seems you need to reformat the code using ./gradlew spotlessApply.

+    }


List<DateFormatter> dateFormatters = this.getAllNamedFormatters(); dateFormatters.addAll(this.getAllCustomFormatters());

this code will duplicate getAllCustomFormatters?

use Stream.concat to concat two list works?

formats is fetched from OpenSearch index mapping, if formats is null, does it means the OpenSearchDataType is a wrapper of CoreType. So in this case, should we use OPENSEARCH_DEFAULT_FORMATS to format to parse the data?

When format is null, it can still be OpenSearchDateType field as there can be date fields without formats (default ones) defined. So I have used OPENSEARCH_DEFAULT_FORMATS to format the date object in those cases.

Please double confirm on UT chagne. does all these date -> timestamp change necessary?

All these assertions directly comparing with legacyTypeName and hence need this update. I think these changes are necessary and only in UT to avoid any breaking changes with type change from ExprCoreType to OpenSearchDateType inside fieldMappings map.

I only find the legacy name change for Date in production code, why the DateNanos changed in test either? https://github.com/opensearch-project/sql/pull/2762/files/ea3e205184dda4e8e0d5ba55cd9cf18eac82c30e#r1683753172

I think this is because when we create OpenSearchDataType instance for every field mapping type, we are creating OpenSearchDateType instance for both Mappingtype.Date and MappingType.DateNanos- https://github.com/opensearch-project/sql/blob/main/opensearch/src/main/java/org/opensearch/sql/opensearch/data/type/OpenSearchDataType.java#L165
and set the mapping type to Date even for DateNanos (not sure why is it this way) - https://github.com/opensearch-project/sql/blob/main/opensearch/src/main/java/org/opensearch/sql/opensearch/data/type/OpenSearchDateType.java#L143
So I think here UT assertion still looking for Mapping type date even for date nanos I believe.
