| Feature | Current status | Version of latest update | Description |
|---|---|---|---|
| Change event streaming | Preview | RTM | Stream changes from SQL Server to Azure Event Hubs. |
| Fuzzy string matching | Preview | RTM | Check if two strings are similar, and calculate the difference between two strings. |
| EDIT_DISTANCE | Preview | RTM | Calculate the number of insertions, deletions, substitutions, and transpositions needed to transform one string to another. |
| EDIT_DISTANCE_SIMILARITY | Preview | RTM | Calculate a similarity value ranging from 0 (indicating no match) to 100 (indicating full match). |
| Half-precision (2-byte) vectors | Preview | RTM | Store vectors using half-precision (2-byte) floating-point values, allowing up to 3996 dimensions in a single vector. |
| JARO_WINKLER_DISTANCE | Preview | RTM | Calculate the edit distance between two strings giving preference to strings that match from the beginning for a set prefix length. |
| JARO_WINKLER_SIMILARITY | Preview | RTM | Calculate a similarity value ranging from 0 (indicating no match) to 100 (indicating full match). |
| Vector index | Preview | RTM | Create and manage approximate vector indexes to find similar vectors to a given reference vector. |
| CREATE VECTOR INDEX | Preview | RTM | Create an approximate index on a vector column to improve performances of nearest neighbors search. |
| VECTOR_SEARCH. | Preview | RTM | Search for vectors similar to a given query vectors using an approximate nearest neighbors vector search algorithm. |
