func (CatalogHooks) AlterTableCloneBehavior ¶

func (CatalogHooks) AlterTableCloneBehavior() catalogplugin.AlterTableCloneBehavior

AlterTableCloneBehavior — fulltext's single hidden table is empty at CREATE-INDEX time (rows land via the populate step or CDC), so no DELETE before clone is needed. Async fulltext is skipped at the whole-index level via SyncDescriptor, not per table.

func (CatalogHooks) BuildSessionVars ¶

func (CatalogHooks) BuildSessionVars() []string

BuildSessionVars — fulltext's tokenizing build reads no algorithm-specific session vars and has no experimental flag; persist only the basic lower_case_table_names (table-name resolution in the rebuild SQL). BuildSessionVars returns nil — fulltext captures no session vars into algo_params, keeping its algo_params byte-compatible with pre-session_vars indexes.

func (CatalogHooks) DefaultOptions ¶

func (CatalogHooks) DefaultOptions() map[string]string

DefaultOptions — fulltext defaults are inferred at build time; no statement-level option JSON is required when the WITH(...) clause is omitted. Matches the legacy catalog.IndexParamsToJsonString path returning "" for an empty option map.

func (CatalogHooks) ExperimentalFlag ¶

func (CatalogHooks) ExperimentalFlag() string

ExperimentalFlag — `experimental_fulltext_index` exists at pkg/frontend/variables.go but is not enforced anywhere today. Returning "" preserves that behavior.

func (CatalogHooks) HiddenTableTypes ¶

func (CatalogHooks) HiddenTableTypes() []string

HiddenTableTypes — fulltext uses a single hidden table holding (doc_id, pos, word) rows clustered by word.

func (CatalogHooks) ParamsFromTree ¶

func (CatalogHooks) ParamsFromTree(_ *tree.Index) (map[string]string, error)

ParamsFromTree — fulltext parses to *tree.FullTextIndex, not *tree.Index, so this hook is never reached for fulltext in practice. The fulltext-specific parser lives at pkg/fulltext/plugin/plan/schema.go::buildFullTextParams and is invoked from BuildFullTextIndexDefs.

func (CatalogHooks) RestoreBehavior ¶

func (h CatalogHooks) RestoreBehavior() catalogplugin.RestoreBehavior

RestoreBehavior — CreateTable populates fulltext's inverted-index hidden table inline for a sync index (CROSS APPLY fulltext_index_tokenize), and the restore's block-level clone APPENDS, so it must be emptied with DELETE … WHERE TRUE before the clone re-supplies it — DeleteBeforeClone is the hidden table. (For an async index the table is empty at CreateTable, so the delete is a harmless no-op.) The compile hook's RestoreInitSQL returns "" — no reindex; clone + CDC catch-up rebuild it.

func (CatalogHooks) ShouldTruncateHiddenTable ¶

func (CatalogHooks) ShouldTruncateHiddenTable(_ string) bool

ShouldTruncateHiddenTable — fulltext has no preserved-across-truncate state; the single hidden table is rebuilt from source rows.

func (CatalogHooks) SupportedIncludeColumnTypes ¶

func (CatalogHooks) SupportedIncludeColumnTypes() []types.T

SupportedOpTypes — fulltext has no metric/op-type concept. SupportedIncludeColumnTypes: this index has no INCLUDE-column support.

func (CatalogHooks) SupportedOpTypes ¶

func (CatalogHooks) SupportedOpTypes() map[string]string

func (CatalogHooks) SupportedPrimaryKeyTypes ¶

func (CatalogHooks) SupportedPrimaryKeyTypes() []types.T

SupportedPrimaryKeyTypes: fulltext imposes no PK-type constraint.

func (CatalogHooks) SupportedVectorTypes ¶

func (CatalogHooks) SupportedVectorTypes() []types.T

SupportedVectorTypes: fulltext has no vector column.

func (CatalogHooks) SyncDescriptor ¶

func (CatalogHooks) SyncDescriptor() catalogplugin.SyncDescriptor

SyncDescriptor — fulltext participates in ISCP CDC when the index is async (per the Async param in IndexAlgoParams). No idxcron action today, matching the legacy inline behaviour.
