Andrew Kyle Purtell commented on PHOENIX-7309:
----------------------------------------------
bq. While Phoenix can do something similar to what HBase shell does, I believe
rather than Phoenix having to read the whole split file (with potentially 10k
or 50k worth of split keys) and create split keys array, it would be great if
HBase can provide public Admin API with input as split file.
HBase is unlikely to agree to have the master read some file from a user
supplied (untrusted) location. My initial reaction is to veto it as
unnecessary, because the functionality already exists in the API, and changes
to public APIs involve some nontrivial work to avoid compatibility issues.
Also, accepting user supplied input from the filesystem means attacker file
level risks become possible.

> Key: PHOENIX-7309
> URL: https://issues.apache.org/jira/browse/PHOENIX-7309
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Rushabh Shah
> Priority: Major
>
> Currently phoenix grammar support specifying splits points while creating a
> table.
> See grammar [here|https://phoenix.apache.org/language/index.html#create_table]
> {noformat}
> CREATE TABLE IF NOT EXISTS "my_case_sensitive_table"
> ( "id" char(10) not null primary key, "value" integer)
> DATA_BLOCK_ENCODING='NONE',VERSIONS=5,MAX_FILESIZE=2000000 split on (?,
> ?, ?)
> {noformat}
> This works fine if you have few split points (less than 10-20).
> But if you want to specify 1000 (or in 10,000s) split points then this API
> becomes very cumbersome to use.
> HBase provides API to create a table with split points text file.
> {noformat}
> hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt', OWNER => 'johndoe'
> {noformat}
> We should also have support in Phoenix to provide split points in a text file.
